Giant cell arteritis with spontaneous remission.

BACKGROUND: Clinical manifestations of giant cell arteritis (GCA) are variable. Whether signs and symptoms present in an explosive fashion or insidiously, once manifest the course is usually progressive unless treatment is initiated. METHODS: A retrospective review of patients with GCA seen in an outpatient neuro-ophthalmology clinic. RESULTS: We report four patients with biopsy-proven GCA who experienced spontaneous remission. Clinical manifestations consisted of headache and diplopia in two patients, constitutional symptoms in one patient and facial pain in another. CONCLUSIONS: Clinicians should be aware of this aspect of the disease in order to avoid a delay in diagnosis and treatment.

The Rare Cancer Network: achievements from 1993 to 2012.

The Rare Cancer Network (RCN), founded in 1993, performs research involving rare tumors that are not common enough to be the focus of prospective study. Over 55 studies have either been completed or are in progress.The aim of the paper is to present an overview of the 30 studies done through the RCN to date, organized by disease site. Five studies focus on breast pathology, including sarcoma, lymphoma, phyllodes tumor, adenoid cystic carcinoma, and ductal carcinoma in situ in young women. Three studies on prostate cancer address prostatic small cell carcinoma and adenocarcinoma of young and elderly patients. Six studies on head and neck cancers include orbital and intraocular lymphoma, mucosal melanoma, pediatric nasopharyngeal carcinoma, olfactory neuroblastoma, and mucosa-associated lymphoid tissue lymphoma of the salivary glands. There were 4 central nervous system studies on patients with cerebellar glioblastoma multiforme, atypical and malignant meningioma, spinal epidural lymphoma and myxopapillary ependymoma. Outside of these disease sites, there is a wide variety of other studies on tumors ranging from uterine leiomyosarcoma to giant cell tumors of the bone. The studies done by the RCN represent a wide range of rare pathologies that were previously only studied in small series or case reports. With further growth of the RCN and collaboration between members our ability to analyze rare tumors will increase and result in better understanding of their behavior and ultimately help direct research that may improve patient outcomes.

Association between IL-18 gene polymorphisms and biopsy-proven giant cell

INTRODUCTION: The objective was to investigate the potential implication of the IL18 gene promoter polymorphisms in the susceptibility to giant-cell arteritis GCA). METHODS: In total, 212 patients diagnosed with biopsy-proven GCA were included in this study. DNA from patients and matched controls was obtained from peripheral blood. Samples were genotyped for the IL18-137 G>C (rs187238), the IL18-607 C>A (rs1946518), and the IL18-1297 T>C (rs360719) gene polymorphisms with polymerase chain reaction, by using a predesigned TaqMan allele discrimination assay. RESULTS: No significant association between the IL18-137 G>C polymorphism and GCA was found. However, the IL18 -607 allele A was significantly increased in GCA patients compared with controls (47.8% versus 40.9% in patients and controls respectively; P = 0.02; OR, 1.32; 95% CI, 1.04 to 1.69). It was due to an increased frequency of homozygosity for the IL18 -607 A/A genotype in patients with GCA (20.4%) compared with controls (13.4%) (IL18 -607 A/A versus IL18 -607 A/C plus IL18 -607 C/C genotypes: P = 0.04; OR, 1.59; 95% CI, 1.02 to 2.46). Also, the IL18-1297 allele C was significantly increased in GCA patients (30.7%) compared with controls (23.0%) (P = 0.003; OR, 1.48; 95% CI, 1.13 to 1.95). In this regard, an increased susceptibility to GCA was observed in individuals carrying the IL18-1297 C/C or the IL18-1297 C/T genotypes compared with those carrying the IL18-1297 T/T genotype (IL18-1297 C/C plus IL18-1297 T/C versus IL18-1297 T/T genotype in GCA patients compared with controls: P = 0.005; OR, 1.61; 95% CI, 1.15 to 2.25). We also found an additive effect of the IL18 -1297 and -607 polymorphisms with TLR4 Asp299Gly polymorphism. The OR for GCA was 1.95 for combinations of genotypes with one or two risk alleles, whereas carriers of three or more risk alleles have an OR of 3.7. CONCLUSIONS: Our results show for the first time an implication of IL18 gene-promoter polymorphisms in the susceptibility to biopsy-proven GCA. In addition, an additive effect between the associated IL18 and TLR4 genetic variants was observed.

Ki-67 MIB1 labelling index and the prognosis of primary TaT1 urothelial cell carcinoma of the bladder.

Aims: To evaluate whether ki-67 labelling index (LI) has independent prognostic value for survival of patients with bladder urothelial tumours graded according to the 2004 World Health Organisation classification. Methods: Ki-67 LI was evaluated in 164 cases using the grid counting method. Non-invasive (stage Ta) tumours were: papilloma (n = 5), papillary urothelial neoplasia of low malignant potential (PUNLMP; n = 26), and low (LG; n = 34) or high grade (HG; n = 15) papillary urothelial carcinoma. Early invasive (stage T1) tumours were: LG (n = 58) and HG (n = 26) carcinoma. Statistical analysis included Fisher and x2 tests, and mean comparisons by ANOVA and t test. Univariate and multivariate survival analyses were performed according to the Kaplan–Meier method with log rank test and Cox’s proportional hazard method. Results: Mean ki-67 LI increased from papilloma to PUNLMP, LG, and HG in stage Ta (p,0.0001) and from LG to HG in stage T1 (p = 0.013) tumours. High tumour proliferation (.13%) was related to greater tumour size (p = 0.036), recurrence (p = 0.036), progression (p = 0.035), survival (p = 0.054), and high p53 accumulation (p = 0.015). Ki-67 LI and tumour size were independent predictors of disease free survival (DFS), but only ki-67 LI was related to progression free survival (PFS). Cancer specific overall survival (OS) was related to ki-67 LI, tumour size, and p27kip1 downregulation. Ki-67 LI was the main independent predictor of DFS (p = 0.0005), PFS (p = 0.0162), and cancer specific OS (p = 00195). Conclusion: Tumour proliferation measured by Ki-67 LI is related to tumour recurrence, stage progression, and is an independent predictor of DFS, PFS, and cancer specific OS in TaT1 bladder urothelial cell carcinoma.

Selective suppression of cytokine secretion in whole blood cell cultures of patients with colorectal cancer.

We have investigated the secretion of interferon alpha (IFN-alpha), IFN-gamma, interleukin-1alpha (IL-1alpha), IL-1beta, IL-2 and tumour necrosis factor alpha (TNF-alpha) in whole blood cell cultures (WBCCs) of colorectal cancer patients upon mitogen stimulation. Whereas the values for IL-1beta and TNF-alpha remained virtually unchanged in comparison with healthy control subjects, WBCCs of colorectal cancer patients secreted significantly lower amounts of IFN-alpha (P < 0.005), IFN-gamma (P < 0.0001), IL-1alpha (P < 0.0001) and IL-2 (P < 0.05). This reduction correlated with the progression of the disease. The total leucocyte and monocyte population were almost identical in both groups. In contrast, a dramatic depletion of lymphocytes was observed in colorectal cancer patients, which affected both lymphocyte counts (P < 0.0005) and their distribution (P < 0.0001). Our results suggest a selective suppression of cytokines in colorectal cancer patients that is related to tumour burden. Several mechanisms might account for this phenomenon, one of which might be lymphocyte depletion.

Artérite á cellules géantes et vitesse de sédimentation normale: plus qu'une exception [Giant cell arteritis and normal sedimentation rate: more than an exception!]

BACKGROUND: Giant cell arteritis (GCA) is a systemic segmental vasculitis of unknown etiology, typically affecting elderly patients. Elevated erythrocyte-sedimentation rate (ESR) is usually found in such patients. PATIENTS AND METHODS: One hundred and twenty three patients underwent temporal artery biopsy in our institution between 1977 and 1995. Among them, 66 (53.7%) biopsies were positive (i.e. histologic findings were very suggestive of GCA). The clinical charts from all patients with positive biopsies were retrieved and 47 were eligible for our study (inadequate data in 19 cases). RESULTS: Seven of the 47 patients with positive biopsies (15%) had a normal ESR and 70% (33/47 cases) had neuro-ophthalmic complications including anterior ischemic optic neuropathy, central retinal artery occlusion, choroidal ischemia and extraocular muscle and/or cranial nerve palsy (III, IV, VI). No differences were found between the groups with normal or elevated ESR as 87.5% (6/7 cases) of the group with normal ESR exhibited neuro-ophthalmic complications. CONCLUSIONS: ESR was normal in 15% of our GCA patients and these patients had the same frequency of neuro-ophthalmic complications as the GCA patients with elevated ESR. Thus, our study does not support the previous concept that patients with higher ESR are more at risk for neuro-ophthalmic complications. GCA with normal ESR is not rare and such patients should be investigated with other blood studies (C-reactive protein) and with fluorescein angiography.

Giant cell arteritis: an updated review.

Giant cell arteritis (GCA) is the most common primary vasculitis of adults. The incidence of this disease is practically nil in the population under the age of 50 years, then rises dramatically with each passing decade. The median age of onset of the disease is about 75 years. As the ageing population expands, it is increasingly important for ophthalmologists to be familiar with GCA and its various manifestations, ophthalmic and non-ophthalmic. A heightened awareness of this condition can avoid delays in diagnosis and treatment. It is well known that prompt initiation of steroids remains the most effective means for preventing potentially devastating ischaemic complications. This review summarizes the current concepts regarding the immunopathogenetic pathways that lead to arteritis and the major phenotypic subtypes of GCA with emphasis on large vessel vasculitis, novel modalities for disease detection and investigative trials using alternative, non-steroid therapies.

Riesenzellarteriitis : Ätiologische Erkenntnisse und diagnostische Herausforderung für den Pathologen [Giant cell arteritis : Etiological knowledge and diagnostic challenge for pathologists].

Giant cell arteritis is a potentially systemic disease of medium-sized and large caliber arteries, showing a preferential manifestation in the extracranial branches of the carotid artery. The diagnosis is oriented to clinical and histomorphological criteria which will be critically reviewed. Particular emphasis is placed on the differentiation from normal aging processes and from healing stages under steroid therapy. In addition, the advances in our understanding of the disease pathomechanism during the last 10 years will be briefly presented as the basis for the hitherto empiric steroid treatment.

Nuclear receptor PPARS function in stem cell differentiation and bone physiology

In adult, bone remodeling is a permanent process, reaching an annual turnover of about 10% of the skeleton. Bone remodeling requires the sequential and coordinated actions of the hematopoietic origin osteoclasts, to remove bone and the mesenchymal origin osteoblasts to replace it. An increased level of bone resorption is the primary cause of age-related bone loss often resulting in osteopenia, and is the major cause of osteoporosis.¦Peroxisome proliferator-activated receptors (PPARs), which are expressed in three isotypes, PPARa, PPARp and PPARy, are ligand-activated transcription factors that control many cellular and metabolic processes, more particularly linked to lipid metabolism. In bone, previous works has shown that PPARy inhibits osteogenesis by favoring adipogenesis from common mesenchymal progenitors. In addition, the pro-osteoclastogenesis activity of PPARy results in an increased bone resorption. Accordingly, treatment with PPARy agonist such as the anti-diabetic drug TZD causes bone loss and accumulation of marrow adiposity in mice as well as in postmenopausal women. The aim of the present thesis work was to elucidate the PPARs functions in bone physiology.¦The initial characterization of the PPARP" bone phenotype mainly revealed a decreased BMD. In vitro studies exploring the potency of mesenchymal stem cells to differentiate in osteoblast showed no differences depending on the genotype. However, we could demonstrate an effect of PPARp in partially inhibiting osteoclastogenesis. These results are further sustained by a study made in collaboration with the group of Dr Kronke, which showed an impressive protection against ovariectomy-generated bone loss when the females are treated with a PPARp agonist.¦Observations in PPARy null mice are more complex. The lab has recently been able to generate mice carrying a total deletion of PPARy. Intriguingly, the exploration of the bone phenotype of these mice revealed paradoxical findings. Whereas short bones such as vertebrae exhibit an elevated BMD as expected, long bones (tibia and femur) are clearly osteoporotic. According to their activity when set in culture, osteoblast differentiation normally occurs. Indeed the phenotype can be mainly attributed to a high density of osteoclasts in the cortical bone of PPARy null mice, associated to large bone resorption areas.¦Our explorations suggest a mechanism that involves regulatory processes linking osteoclastogenesis to adipogenesis, the latter being totally absent in PPARy null mice. Indeed, the lack of adipose tissue creates a favorable niche for osteoclastogenesis since conditioned medium made from differentiated adipocyte 3T3L1 inhibited osteoclastogenesis from both PPARy-/- and WT cells. Thus, adipokines deficiency in PPARy-/- mice contributes to de- repress osteoclastogenesis. Using specific blocking antibody, we further identified adiponectin as the major player among dozens of adipokines. Using flow cytometry assay, we explored the levels at which the osteoclastic commitment was perturbed in the bone marrow of PPARy-/- mice. Intriguingly, we observe a general decrease for hematopoietic stem cell and lineage progenitors but increased proportion of osteoclast progenitor in PPARy-/- bone marrow. The general decrease of HSC in the bone marrow is however largely compensated by an important extra-medullary hematopoeisis, taking place in the liver and in the spleen.¦These specific characteristics emphasize the key role of PPARy on a cross road of osteogenesis, adipogenesis and hematopoiesis/osteoclastogenesis. They underline the complexity of the bone marrow niche, and demonstrate the inter-dependance of different cell types in defining bone homeostasis, that may be overseen when experimental design single out pure cell populations.¦Chez l'adulte, même après la fin de la croissance, le renouvellement des os se poursuit et porte sur environ 10% de l'ensemble du squelette adulte, par année. Ce renouvellement implique à la fois des mécanismes séquentiels et coordonnés des ostéoclastes d'origine hématopoïetique, qui dégradent l'os, et des ostéoblastes d'origine mésenchymale, qui permettent la régénération de l'os. La perte en densité osseuse due à l'âge entraîne un fort niveau de résorption, conduisant souvent à une ostéopénie, elle-même cause de l'ostéoporose.¦Les trois isotypes PPAR (Peroxisome proliferator-activated receptor, PPARa, PPARp, et PPARy) sont des récepteurs nucléaires qui contrôlent de nombreux mécanismes cellulaires et métaboliques, plus particulièrement liés au métabolisme lipidique. Au niveau osseux, des travaux précédents ont montré que PPARy inhibe l'ostéoblastogenèse en favorisant la formation d'adipocytes à partir de la cellule progénitrice commune. De plus, l'activité pro- ostéoclastogénique de PPARy induit une résorption osseuse accrue. Condormément à ces observations, les patients diabétiques traités par les thiazolidinediones qui agissent sur PPARy, ont un risque accrue d'ostéoporose liée à une perte osseuse accrue et un accroissement de l'adiposité au niveau de la moelle osseuse. Dans ce contexte, l'objectif de mon travail de thèse a été d'élucider le rôle des PPAR dans la physiologie osseuse, en s'appuyant sur le phénotype des souris porteuses de mutation pour PPAR.¦La caractérisation initiale des os des souris porteuses d'une délétion de ΡΡΑΕφ a principalement révélé une diminution de la densité minérale osseuse (DMO). Alors que l'ostéogenèse n'est pas significativement altérée chez ces souris, l'ostéoclastogenèse est elle augmentée, suggérant un rôle modérateur de ce processus par ΡΡΑΕΙβ. Ces résultats sont par ailleurs soutenus par une étude menée par le groupe du Dr Krônke en collaboration avec notre groupe, et qui monte une protection très importante des souris traitées par un activateur de PPARP contre l'ostéoporose provoquée par l'ovariectomie.¦Les observations concernant PPARy donnent des résultats plus complexes. Le laboratoire a en effet été capable récemment de générer des souris portant une délétion totale de PPARy. Alors que les os courts chez ces souris présentent une augmentation de la DMO, comme attendu, les os longs sont clairement ostéoporotiques. Ce phénotype corrèle avec une densité élevée d'ostéoclastes dans l'os cortical de ces os longs. Deux processus semblent contribuer à ce phénotype. En premier lieu, nous démontrons qu'un milieu conditionné provenant de cultures de cellules 3T3-L1 différenciées en adipocytes contiennent une forte activité inhibitrice d'osteoclastogenesis. L'utilisation d'anticorps neutralisant permet d'identifier l'adiponectine comme l'un des facteurs principaux de cette inhibition. Les souris PPARy étant totalement dépourvues d'adipocytes et donc de tissu adipeux, la sécrétion locale d'adiponectine dans la moelle osseuse est donc également absente, entraînant une désinhibition de l'ostéoclastogenèse. En second lieu, des analyses par FACS révèle une proportion accrue des cellules progénitrices d'ostéoclastes dans la moelle osseuse. Cela s'accompagne par une diminution globale des cellules souches hématopoïétiques, qui est cependant largement compensée par une importante hématopoëise extra-médullaire, dans le foie comme dans la rate.¦L'ensemble de notre travail montre toute l'importance de PPARy au carrefour de l'ostéogenèse, adipogenèse, et hématopoëise/osteoclastogenèse. Il souligne la complexité de la niche que représente la moelle osseuse et démontre l'inter-dépendance des différents types cellulaires définissant l'homéostasie osseuse, complexité qui peut facilement être masqué lorsque le travail expérimental se concentre sur le comportement d'un type cellulaire donné.

Carcinomes épidermoïdes de l'hypopharynx et du larynx : prise en charge fondée sur les preuves Squamous cell carcinoma of the hypopharynx and larynx: evidence-based care.

Les carcinomes épidermoïdes de l'hypopharynx et du larynx peuvent être traités par chirurgie et/ou radiothérapie en fonction de la taille tumorale. Pour les petites tumeurs, les résultats sont équivalents. Pour les tumeurs localement avancées, l'approche chirurgicale est mutilante et nécessite une (pharyngo)laryngectomie totale. La chimioradiothérapie exclusive a montré tout son intérêt mais au prix de séquelles tardives. Dans le but de diminuer ces séquelles et les mutilations, la chimiothérapie d'induction par cisplatine, docétaxel et 5FU à visée de préservation d'organe devient le standard de traitement mais il manque des études solides de comparaison de cette approche avec la chimioradiothérapie exclusive. Il n'est pas possible de conclure quant à la supériorité d'un schéma en survie globale. Quand la chimiothérapie d'induction est choisie, les modalités de potentialisation éventuelle de la radiothérapie ne sont pas établies. Squamous cell carcinomas of larynx and hypopharynx can be treated by surgery and/or radiotherapy according to tumor size. For small tumors, the results are similar. For locally advanced tumors, the surgical approach is mutilating and requires a total (pharyngo)laryngectomy. Exclusive chemoradiotherapy has shown its interest at the cost of late sequelae. In order to reduce these effects and mutilation, induction chemotherapy with cisplatin, docetaxel and 5FU for organ preservation becomes the standard treatment but there are no solid studies comparing this approach with the exclusive chemoradiotherapy. And it is not possible to conclude as to the superiority of a scheme in terms of overall survival. When chemotherapy is chosen, the modalities of any potentiation of radiation have not been yet established.

Immunohistochemical analysis of bone morphological protein signaling pathway in human myometrium.

We assessed by immunohistochemistry the expression of the phosphorylated (activated) form of Smad1 and 5 (P-SMAD1/5), of Noggin and of two smooth muscle cell markers (α-SMA and SM22) in a series of human myometrium samples and in a smooth muscle cell line derived from human myometrium (HUt-SMC, PromoCell, USA). Myometrium samples were removed from two cadavers (a fetus at 26weeks of gestation and a neonate) and from ten non-menopausal women who underwent hysterectomy for adenomyosis and leiomyoma. P-SMAD1/5 expression was never detected in myometrium (both normal and pathological specimens), but only as a nuclear positive staining in glandular and luminal epithelial cells in sections in which also the endometrial mucosa was present. Noggin was strongly expressed especially in myometrium and adenomyosis samples from non-menopausal patients in comparison to the neonatal and fetal myometrium specimens in which muscle cells were less positive. In more than 95% of HUt-SMCs, α-SMA and Desmin were co-expressed, indicating a pure smooth muscle phenotype. When progesterone was added to the culture medium, no P-SMAD1/5 expression was detected, whereas the expression Noggin and SM22, a marker of differentiated smooth muscle cells, increased by 3 fold (p=0.002) and 4.3 fold (p=0.001), respectively (p=0.002). Our results suggest that, in non-menopausal normal human myometrium, the BMP pathway might be inhibited and that this inhibition might be enhanced by progesterone, which increases the differentiation of smooth muscle cells (SM22 levels). These findings could help in the identification of new mechanisms that regulate uterine motility.

Gelatinase expression and proteolytic activity in giant-cell arteritis

Objectives: Gelatinases (MMP2 and MMP9) are expressed in giant-cell arteritis (GCA) and are thought to play a role in vessel disruption. However, their activation status and enzymatic activity have not been evaluated. Our aim was to investigate the distribution and proteolytic activity of gelatinases in GCA lesions at different stages. Methods: Expression of MMP2, MMP9, MMP2-activator MMP14 and their natural inhibitors TIMP1 and TIMP2 was determined by real-time PCR and immunohistochemistry in temporal artery sections from 46 patients and 12 controls. MMP activation status and enzymatic activity were assessed by gelatin and film in situ zymography. Results: Vascular smooth muscle cells from normal specimens constitutively expressed pro-MMP2 and its inhibitor TIMP2 with no resulting proteolytic activity. In GCA MMP2, MMP9 and MMP14 were strongly expressed in their active form by infiltrating leucocytes. Inflamed arteries also expressed TIMP1 and TIMP2. However, the MMP9/TIMP1 and MMP2/TIMP2 ratios were higher in patients compared with controls, indicating an increased proteolytic balance in GCA which was confirmed by in situ zymography. Maximal gelatinase expression and activity occurred at the granulomatous areas surrounding the internal elastic lamina (IEL). Myointimal cells also expressed MMPs and exhibited proteolytic activity, suggesting a role for gelatinases in vascular remodelling and repair. Conclusions: GCA lesions show intense expression of gelatinases. Activators and inhibitors are regulated to yield enhanced gelatinase activation and proteolytic activity. Distribution of expression and proteolytic activity suggests that gelatinases have a major role not only in the progression of inflammatory infiltrates and vessel destruction but also in vessel repair.

Primary γδ T cell lymphoma of the lung: report of a case with features suggesting derivation from intraepithelial γδ T lymphocytes [Primary gammadelta T cell lymphoma of the lung: report of a case with features suggesting derivation from intraepithelial gammadelta T lymphocytes].

T cell lymphoma of γδ T cell origin is a rare disease that mainly involves extranodal sites and shows aggressive clinical behavior. Here, we report a case of primary γδ T cell lymphoma of the lungs with epitheliotropism in the respiratory epithelium, a feature somewhat reminiscent of what is observed in enteropathy-associated T cell lymphoma. A 63-year-old man presented with chest pain and dyspnea on exertion, weight loss, and general weakness. On a positron emission tomography (PET) scan, multiple hypermetabolic lesions were found in both lungs. Microscopic examination of the wedge lung biopsy revealed nodular infiltration of monomorphic, medium- to large-sized atypical lymphocytes with round nuclei, coarse chromatin, and a variable amount of clear to eosinophilic cytoplasm. Of note, intraepithelial lymphocytosis by atypical lymphoid cells was observed in the respiratory epithelium within and around the nodule. Immunohistochemically, the tumor cells were CD3+, TCRβF1-, TCRγ+, CD5-, CD7+, CD20-, CD79a-, CD30-, CD4-, CD8-, CD10-, BCL6-, CD21-, CD56+, CD57-, and CD138-, and expressed cytotoxic molecules. Epstein-Barr virus (EBV) was not detected by an in situ hybridization assay for EBV-encoded RNA. Interestingly, CD103 was expressed by a subset of tumor cells, especially those infiltrating the epithelium. T cell clonality was detected by multiplex PCR analysis of TRG and TRD gene rearrangements. After 2 months of systemic chemotherapy, PET scan showed regression of the size and metabolic activity of the lesions. This case represents a unique γδ T cell lymphoma of the lungs showing epitheliotropism by CD103+ γδ T cells that is suggestive of tissue-resident γδ T cells as the cell of origin.

Naevus naevocellulaire achrome palpébral prenant l'aspect d'un carcinome basocellulaire [Nevus mimicking a basal cell carcinoma of the eyelid].

A clinicopathologic case of a 41-year-old female patient exhibited a single cutaneous tumor at the inner part of the free margin of the inferior left eyelid. It was a pink, fleshy, and nodular well-circumscribed exophytic mass with thin vessels on its surface. Experienced already for 20 years, this lesion had been observed 6 years before and has not exhibited much change since then. However, its clinical appearance argued for a possible small basal cell carcinoma, which had grown over the inferior left lachrymal duct. After surgical removal, histopathology showed that the tumor was an amelanotic dermal nevus. No disturbance of lachrymal drainage was observed after surgery. This case shows that nodular amelanotic tumors of the eyelid, even when located on the inner segment of the eyelid, may be a nevus.
