Kératose précancéreuse palpébrale [Eyelid precancerous keratosis].

A 25-year-old-male patient had one keratinized tumor on the inferior right eyelid, first observed 5 months before. Its size had been increasing for the last three weeks. The visual function was normal. Clinical examination disclosed a papillomatous lesion on the cutaneous middle part of the eyelid. A surgical excision was performed under local anesthesia. The histopathological study found a papillomatous epidermal proliferation with both structural and cytological atypias, concluding with a precancerous keratosis of the eyelid.

Inflammation palpébrale pseudotumorale. A propos d'une observation anatomo-clinique [Pseudotumoral eyelid inflammation. Apropos of an anatomo-clinical case].

A clinicopathological case of a 76-year-old male patient with a chronic inflammatory change of the inferior left eyelid is reported. The inflammation appeared as a reddish area of the inner part of the eyelid, without sharp limits, but with loss of lashes. Numerous local treatments did not to cure this condition. As some true eyelid tumors may mimic an inflammation during growth and, for example, sebaceous carcinoma may clinically present as chronic unilateral blepharitis, a surgical excisional biopsy was performed on this left eyelid. Its histopathological study showed a granulomatous inflammation, which was typical of a simple chalazion. This case clearly illustrates that the chalazion may not always appear as a limited nodular inflammation of the eyelid, but may have a more diffuse clinical presentation.

Clinicopathological features of eyelid skin tumors. A retrospective study of 5504 cases and review of literature.

Eyelid tumors are the most common neoplasm in daily ophthalmology practice and encompass a wide variety of benign and malignant tumors. In this retrospective study, we report the clinical and histological features of 5504 eyelid skin tumors diagnosed at the Laboratory of Ophthalmopathology of the Hôpital Ophtalmique Jules Gonin, Lausanne, Switzerland, between January 1989 and December 2007. Benign tumors largely predominated over malignant ones, representing 84% of cases in this series, and the 5 most frequent subtypes were squamous cell papilloma (26%), seborrheic keratosis (21%), melanocytic nevus (20%), hidrocystoma (8%), and xanthoma/xanthelasma (6%). Basal cell carcinoma was the most frequent malignant tumor (86%), followed by squamous cell carcinoma (7%) and sebaceous carcinoma (3%). For several tumor subtypes, there was a poor correlation between clinical and histological diagnosis, stressing the numerous pitfalls in the diagnosis of eyelid tumors. We further discuss our results with reference to previously published series.

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.

Paracoccidioidomicose primária de pálpebra e conjuntiva

Paracoccidioidomycosis is the most frequent systemic mycosis in Brazil, but ocular involvement is rare and, if present, often secondary to another site. The authors report a case of paracoccidioidomycosis of eyelid and conjunctiva where no extraocular focus was found. A brief review of the literature is made discussing the importance of diagnostic suspecion in a population at risk and early treatment for a good visual prognosis.

Comparison of antibiotic drops placed in the conjunctival cul-de-sac to antibiotic ointment applied to the lid margin in reduction of bacterial colonization on the lid margin.

PURPOSE: To compare the efficacy of antibiotic drops placed in the conjunctival cul-de-sac to antibiotic ointment applied to the lid margin in reduction of bacterial colonization on the lid margin. METHODS: A randomized, prospective, single-masked study was conducted on 19 patients with culture-proven colonization of bacteria on the lid margins. Ophthalmic eligibility criteria included the presence of > or =50 colony-forming units/mL (CFU/mL) of bacteria on both right and left lids. Each patient received one drop of ofloxacin in one eye every night for one week, followed by one drop once a week for one month. In the same manner, each patient received bacitracin ointment (erythromycin or gentamicin ointment if lid margin bacteria were resistant to bacitracin) to the lid margin of the fellow eye. Quantitative lid cultures were taken at initial visit, one week, one month, and two months. Fifteen volunteers (30 lids) served as controls. Lid cultures were taken at initial visit, one week, and one month. RESULTS: Both antibiotic drop and ointment reduced average bacterial CFU/mL at one week and one month. Average bacterial CFU/mL reestablished to baseline values at two months. There was no statistically significant difference between antibiotic drop and ointment in reducing bacterial colonization on the lid margin. CONCLUSION: Antibiotic drops placed in the conjunctival cul-de-sac appear to be as effective as ointment applied to the lid margins in reducing bacterial colonization in patients with > or =50 CFU/mL of bacteria on the lid margins.

Melanose da margem palpebral com suspeita de malignidade: relato de caso

Apresenta-se relato de caso de paciente parda, com 47 anos de idade, havendo lesão pigmentada na margem palpebral inferior do olho direito, de aspecto irregular e heterogêneo, suspeitando-se clinicamente de lesão maligna. A paciente foi tratada com base no resultado da citologia de impressão e diagnosticada pelo exame histológico. Demonstra-se a importância da citologia para o planejamento da ressecção de lesões suspeitas como um método seguro e efetivo para assim se evitar cirurgias em áreas extensas da superfície ocular e de anexos.

Alterações da margem palpebral associadas ao ectrópio

OBJETIVO: Investigar alterações da margem palpebral em portadores de ectrópio. MÉTODOS: Foi feito estudo observacional, do qual participaram 53 portadores de ectrópio palpebral e 25 portadores de dermatocálase (grupo controle), estudando-se, a partir de imagens digitais, a posição dos cílios e a presença de inflamações na margem palpebral. Os dados foram submetidos a análise estatística. RESULTADOS: Os portadores de ectrópio apresentaram com maior freqüência diminuição do número de cílios, perda da convexidade, triquíase e distiquíase quando comparados aos indivíduos do grupo controle. CONCLUSÃO: O portador de ectrópio possui alterações da margem palpebral provavelmente decorrentes do processo inflamatório crônico que ocorre na região.

Avaliação quantitativa das dimensões óculo-palpebrais em portadores de cavidade anoftálmica em uso de prótese ocular externa

OBJETIVOS: Avaliar o posicionamento palpebral em portadores de cavidade anoftálmica com e sem prótese ocular externa, utilizando o processamento de imagem digital. MÉTODOS: Dezoito pacientes foram avaliados qualitativa e quantitativamente na Faculdade de Medicina de Botucatu - Universidade Estadual Paulista - UNESP, com e sem a prótese externa. Usando imagens obtidas por filmadora e processadas usando o programa Scion Image, mediu-se a altura do sulco palpebral superior, a altura da fenda palpebral e os ângulos palpebrais dos cantos interno e externo. RESULTADOS: Pseudo-estrabismo e sulco palpebral superior profundo foram as alterações mais freqüentes ao exame externo. Houve diferença significativa em todas as variáveis estudadas, com diminuição da altura do sulco palpebral superior, aumento da área da fenda palpebral e aumento dos ângulos palpebrais interno e externo quando o paciente estava usando a prótese externa. CONCLUSÃO: Todos os pacientes avaliados apresentaram algum tipo de anormalidade órbito-palpebral, o que reflete a dificuldade em se proporcionar ao portador de cavidade anoftálmica um aspecto idêntico ao que existe na órbita normal. O processamento de imagens digitais permitiu avaliação objetiva das dimensões óculo-palpebrais, o que poderá contribuir nas avaliações seqüenciais dos portadores de cavidade anoftálmica.

Paracoccidioidomycosis: study of six cases with ocular involvement

We present 6 patients with ocular involvement due to paracoccidioidomycosis. All cases were confirmed by the finding of Paracoccidioides brasiliensis in histopathological or direct mycologic examination of material from the lesion in the eyelid or conjunctiva. In two cases the bulbar conjunctiva was also involved, in another the cornea, and still another patient developed endophthalmitis. The presence of this mutilating disease which may lead to blindness should be suspected when chronic blepharitis or palpebral ulcerated papular lesions are detected in patients from endemic areas of paracoccidioidomycosis. This etiology should also be suspected in patients with anterior and posterior uveitis after discarding the most frequent causes of this condition. © 1988 Kluwer Academic Publishers.

Ectrópio palpebral: Características e relação com alterações óculo-palpebrais

Objective: To evaluate the gender and the characteristics of the ectropion carriers in our region. Methods: A retrospective study was done evolving 112 ectropion carriers. The sex, race, eyelashes alterations (trichiasis and distichiasis), anterior and posterior blepharitis, conjunctival redness, íris color and pterygium presence were evaluated. Gender data were correlated to ectropion classification (involutional, cicatricial, mechanic or paralytic) and submitted to statiscal analysis. Results: The eyelid ectropion occurred more between 71 and 80 years old.The involutional ectropion was the most frequently observed (66,07%), followed by the cicatricial, mechanic, associated types and paralytic. The majority of the patients were male (70,53%), with White skin. Trichiasis (21,42%) and distichiasis (4,46%) were associated to the ectropion eyelid and mainly in the involutional ectropion carriers. Half of the sample had blepharitis and the majority of the patients had red eye (60%) and brown iris (63,39%). Perygium was absent in the majority of the patients. Conclusion: The involutional ectropium is the most frequently observed in our region, mainly in elderly, male, White skin, brown iris and associated to trichiasis, blepharitis and red eyes.

Unexpected bleeding following eyelid tumor resection leading to the rare diagnosis of acquired haemophilia.

BACKGROUND: Our goal is to report for the first time in the literature a case of uncontrolled bleeding after an oculoplastic surgical procedure leading to the diagnosis of acquired haemophilia. HISTORY AND SIGNS: An 82-year-old patient underwent tumor excision and reconstruction of his right lower eyelid. On the same day, uncontrolled bleeding occurred that resisted optimal blood pressure control, external compression, surgical haemostasis and wound revision. Usual coagulation screening tests were normal, except for a slightly prolonged activated partial thromboplastin time. THERAPY AND OUTCOME: Extensive coagulation check was performed, which showed a severely reduced factor VIII due to the presence of an inhibitor. The bleeding was immediately stopped after administration of recombinant factor VIIa. After healing of the wound, factor VIIa treatment was replaced by immunosuppressive therapy. The factor VIII inhibitor became unmeasurable and remained so for three months after stopping the immunosuppressive therapy. CONCLUSIONS: Ophthalmologists confronted with unexpected uncontrolled bleeding should think about the possibility of blood dyscrasia, in particular acquired haemophilia.

Occurrence and expression of p53 suppressor gene and c-Myc oncogene in dog eyelid tumors

Purpose: To detect the occurrence and expression of the suppressor gene p53 and of the oncogene c-Myc in eyelid tumors of dogs using the PCR, RT-PCR, PCR-ELISA and RT-PCR-ELISA techniques. These genes have not been described in dog eyelid tumors before. Methods: Nine samples of eyelid or third eyelid epithelial tumors were obtained from the archives of the Department of Veterinary Pathology. Tumor diagnosis was confirmed by evaluation of hematoxylin-eosin stained sections, and immunohistochemistry for cytokeratin AE1/AE3 and vimentin V9. A canine mammary tumor was used for positive control. Agarose gel electrophoresis, PCR-ELISA and RT-PCR-ELISA were used to detect p53 and c-Myc genes. Results: The occurrence of p53 was detected in most of the eyelid tumors and third eyelid tumors studied (88.8%, n = 8) and was expressed in 75% of the positive samples, as indicated by ELISA. The c-Myc gene was found in 77.7% (n = 7) of the samples and was expressed in eight samples. Conclusions: Eyelid and third eyelid tumors of dogs express both the p53 and the c-Myc genes as shown by PCR and RT-PCR. However, PCR ELISA and RT-PCR ELISA were more efficient in assessing occurrence and expression of these genes because they identified amplified products that were not detected by agarose gel electrophoresis. © 2010 American College of Veterinary Ophthalmologists.

Otorhinolaryngological Findings In A Group Of Patients With Rheumatic Diseases.

Otorhinolaryngological manifestations of rheumatologic diseases represent a great challenge not only to the generalistphysician but also to the ENT doctor andrheumatologist. They often represent early manifestations of an autoimmune disorder which requires prompt and aggressive immunosuppressive treatment. Auditory, nasal, laryngeal and eye symptoms can be the first manifestation of rheumatic diseases and their proper assessment helps the doctor to identify signs of disease activity. The objective of this study is to identify the ENT manifestations in patients with rheumatic diseases in a high complexity hospital, regarding facilitating an early diagnosis and treatment. We performed clinical and complete otorhinolaryngological evaluations in patients selected from the outpatient rheumatology in a standardized manner by the use of a standardized form filling during the secondhalf of 2010. In the study group, systemic lupus erythematosus (SLE) patients had predominantly laryngeal manifestations, while patients with Sjögren's syndrome showed a higher prevalence of otologic manifestations. Changes in audiometric tests were found in 53% of Wegener's granulomatosis (WG) patients, 80% of relapsing polychondritis (RP), 33% of systemic lupus erythematosus (SLE) and 50% of Churg-Strauss syndrome (SCS). Regarding nasal alterations, these were found so prevalent in all conditions, especially Churg-Strauss syndrome. This study demonstrated that most patients treated in our hospital has the ENT signs and symptoms commonly associated in previous studies on rheumatic diseases, but further studies with a larger number of patients must be made to establish such relations.
