Multiple Haemangiomas, Diaphragmatic Eventration and Beckwith-Wiedemann Syndrome: An Unusual Association

A 6-month-old girl with Beckwith-Wiedemann syndrome, multiple haemangiomas (axillary, laryngeal, pulmonary and hepatic) and diaphragmatic eventration was reported. All tumours responded to treatment with propranolol. The surgical correction of diaphragmatic eventration was crucial to a better outcome.

Non-invasive prenatal diagnosis of multiple endocrine neoplasia type 2A using COLD-PCR combined with HRM genotyping analysis from maternal serum.

The multiple endocrine neoplasia type 2A (MEN2A) is a monogenic disorder characterized by an autosomal dominant pattern of inheritance which is characterized by high risk of medullary thyroid carcinoma in all mutation carriers. Although this disorder is classified as a rare disease, the patients affected have a low life quality and a very expensive and continuous treatment. At present, MEN2A is diagnosed by gene sequencing after birth, thus trying to start an early treatment and by reduction of morbidity and mortality. We first evaluated the presence of MEN2A mutation (C634Y) in serum of 25 patients, previously diagnosed by sequencing in peripheral blood leucocytes, using HRM genotyping analysis. In a second step, we used a COLD-PCR approach followed by HRM genotyping analysis for non-invasive prenatal diagnosis of a pregnant woman carrying a fetus with a C634Y mutation. HRM analysis revealed differences in melting curve shapes that correlated with patients diagnosed for MEN2A by gene sequencing analysis with 100% accuracy. Moreover, the pregnant woman carrying the fetus with the C634Y mutation revealed a melting curve shape in agreement with the positive controls in the COLD-PCR study. The mutation was confirmed by sequencing of the COLD-PCR amplification product. In conclusion, we have established a HRM analysis in serum samples as a new primary diagnosis method suitable for the detection of C634Y mutations in MEN2A patients. Simultaneously, we have applied the increase of sensitivity of COLD-PCR assay approach combined with HRM analysis for the non-invasive prenatal diagnosis of C634Y fetal mutations using pregnant women serum.

Watermelon Stomach, Hemorrhagic Pericarditis, Small Cell Carcinoma of the Lung and Synchronous Squamous Cell Carcinoma of the Tongue Base

Based on a case of gastric antral vascular ectasia (watermelon stomach) that was associated with hemorrhagic pericarditis, small cell lung carcinoma with mediastinal lymph node metastases and a synchronous squamous cell carcinoma of the base of the tongue, the authors made a review of the clinical, endoscopic and histopathological aspects of this type of gastropathy, and its association with other diseases, and of the results of its endoscopic therapy. The causes of hemorrhagic pericarditis are considered, emphasizing the necessity to know if the effusion has a malignant etiology. To the best of our knowledge the association of watermelon stomach to small cell lung carcinoma and squamous cell carcinoma of the base of the tongue has not yet been described. Extensive metastases to mediastal lymph nodes are common to small cell lung carcinoma.

Carcinome basocellulaire associé à un papillome de l'angle interne de la paupière [Basal cell carcinoma associated with a squamous cell papilloma at the inner part of the eyelid].

There are numerous variants of cutaneous tumors involving the eyelids. Tumors of a different nature may at times be observed simultaneously in the same area of the eyelid. A clinicopathologic case of a 36-year-old male patient with 2 different cutaneous tumors at the nasal part of the left eyelid is reported. One was a nodular tumor on the inner canthus with a pearly appearance; the other had a papillomatous pattern. After surgical removal, the histopathological study of the tumors disclosed a typical basal cell carcinoma and a squamous cell papilloma. Both tumors can be commonly observed on the eyelids and surgical excision cured the patient.

Potential value of biliary CEA assay in early detection of colorectal adenocarcinoma liver metastases.

Elevation of the biliary CEA level in patients with liver metastases from colorectal carcinoma has been reported. The aim of this study is to determine the potential value of biliary CEA assay in the early detection of liver metastases. Biliary and serum CEA levels were determined in patients operated on for a colorectal cancer and in control groups. Among 13 patients with liver metastases from colorectal carcinomas, biliary CEA levels were markedly elevated (> 40 ng/ml) in nine, moderately elevated (5-40 ng/ml) in two and normal (arbitrarily defined as < 5 ng/ml) in two. Of 28 patients with primary colorectal carcinoma without detectable hepatic secondaries, three had marked CEA elevation in the bile, 10 had moderate CEA elevation and 15 had normal levels. Among nine patients with non-malignant hepatobiliary pathology, there was one marked biliary CEA elevation, one moderate elevation and seven normal levels. None of the 13 individuals with no identified hepatobiliary pathology had elevated biliary CEA levels. The follow-up of patients with a primary colorectal tumour, no evidence of hepatic secondaries and a biliary CEA elevation is of particular interest. If subsequent appearance of liver metastases is found in such cases, intra-operative biliary CEA assay could be considered a valuable diagnostic test. Further studies will then have to prove the possible benefit of a specific treatment for this group of patients.

Ostéo-arthropathie hypertrophiante révélatrice d'un hémangio-endothéliome épithélioïde multifocal hépatique et pulmonaire [Hypertrophic osteoarthropathy disclosing hepatic and pulmonary multifocal epithelioid hemangioendothelioma]

Epithelioid hemangioendothelioma is a rare, low-grade vascular malignancy reported for the first time in 1982 by Weiss and Enzinger. It involves one or, more rarely, several organs. We report a case involving the lungs and liver, in which the first manifestation was symptomatic hypertrophic osteoarthropathy. Findings four years after the diagnosis included very slow tumor spread, resolution of symptoms, and stabilization of radiological changes.

Repeated surgical excision for an unusual variant of nephroblastoma: case report and review of the literature.

Bilateral fetal rhabdomyomatous nephroblastoma is a rare variant of Wilms' Tumor. The authors report the evolution over 48 months of a 10-month-old baby with bilateral nephroblastoma for which a left nephrectomy was initially performed. A right kidney tumor was enucleated preserving the kidney. The transformation of the primary tumor into a completely differentiated cystic nephroblastoma or nephromalike tumor and the appearance of a metachronous lesion was seen. This report emphasizes the role of nephron-sparing surgery in bilateral Wilms' Tumor when a benign transformation occurs under chemotherapy.

Etude épidémiologique inter-régionale suisse du risque de tumeur controlatérale du sein [Swiss interregional epidemiologic study of the risk of cancer in the contralateral breast].

This epidemiologic investigation in three Swiss regions (Geneva, St. Gall-Appenzell, Vaud) included 5,193 women diagnosed as having a first primary breast cancer. The patients were followed up for ten years (the observation totalled 24,994 women-years). Overall, these results confirmed that the relative risk of a second breast cancer was greatly increased during the first year following the primary diagnosis, but this was largely due to simultaneously discovered contralateral tumours. Beyond the first year of follow-up, the relative risk of a second tumour was lower but still significantly greater than unity. No significant diminution of the excess risk was observed in the first 10 years of follow-up. Relative risk of a second breast cancer was generally higher before age 50, independently of the latency. The relative risk of a second breast cancer differed significantly from one region to another, possibly due to specific techniques of registration.

Association naevus et papillome de la caroncule. A propos d'un cas observation anatomo-clinique [Papillomatous and nevus of the caruncle].

A 63-year-old male patient was operated of a single conjunctival papillomatous lesion located on the left caruncle. The curative tumoral excision was followed by its histological analysis. Histologically, the tumor associated an epithelial squamous papilloma with a subepithelial nevus, confirming a combination of two different lesions.

Adenocarcinome au sein d'un adenome pleomorphe de la glande lacrymale. A propos d'un cas. [Adenocarcinoma in a pleomorphic adenoma of the lacrimal gland: a case study]

PURPOSE: To report a patient with an adenocarcinoma in a pleomorphic adenoma of the lacrimal gland. Adenocarcinoma constitutes a distinct group of epithelial malignancies of the lacrimal gland. METHODS: The clinical presentation, workup, surgical approach, and pathological findings were reviewed. RESULTS: A 56-year-old man presented with a 3-month history of a lacrimal fossa mass. This patient presented a painless mass in the upper outer eyelid with significant displacement of the globe. The tumor was localized to the lacrimal gland. Radiological investigations showed a round, well-defined lesion in the fossa of the lacrimal gland. We performed a lateral orbitotomy; en bloc resection was accomplished. The final specimen showed an adenocarcinoma in a pleomorphic adenoma. No recurrences were detected during follow-up. CONCLUSION: Although adenocarcinoma has rarely been reported in association with a pleomorphic adenoma of the lacrimal gland, this combination can exist. If the malignant tumor is limited in the pleomorphic adenoma, the prognosis appears to be better than in cases of local extension. Adjuvant therapy, radiation or others, are not useful.

Adenocarcinoma e tumor estromal (GIST) sincrônicos no estômago: uma rara ocorrência

A concomitant epithelial and stromal tumor in stomach is unusual in the literature. The purpose of this paper is to report the case and it's therapeutic management. A 72 year old black male patient , which upper digestive endoscopy showed a gastric neoplasm (Borrmann III) at incisura angularis and the biopsy revealed adenocarcinoma. A subtotal gastrectomy with D2 limphadenectomy and Roux-en-Y reconstruction was performed. The histopathology studies confirmed an adenocarcinoma and a gastric stromal tumor, whose immunohistochemical exam was compatible to GIST. Seventeen months after surgery, a computadorized tomography revealed a retrogastric tumor and laparotomy was indicated to remove the lesion.

Expression of betacatenin in carcinoma in pleomorphic adenoma, pleomorphic adenoma and normal salivary gland: an immunohistochemical study

OBJECTIVES: Pleomorphic adenomas are the most frequent type of epithelial salivary gland neoplasms, and their malignant counterpart, the carcinoma in pleomorphic adenomas, is much less common. Beta-catenin is a cell adhesion molecule associated with the invasion and metastasis of carcinomas of the head and neck, esophagus. The objective of this study was to detect the expression of beta-catenin in pleomorphic adenomas, carcinomas in pleomorphic adenomas and normal salivary glands to discuss its role in the development of these two lesions. STUDY DESIGN: The expression of beta-catenin (BD Transduction Laboratories) was analyzed by immunohistochemistry in formalin-fixed, paraffin embedded specimens by the avidin-biotin-peroxidase complex method in 16 pleomorphic adenomas (12 from minor salivary glands), 3 carcinomas in pleomorphic adenomas (all from palate) and 10 normal salivary glands as control group (5 from major and 5 from minor salivary glands). RESULTS: All cases of glands, adenomas and carcinomas in pleomorphic adenomas have membranous and cytoplasmic immunostaining. Nuclear beta-catenin immunostaining was not observed. The antibody presented a fine granular arrangement in the cytoplasm and cellular membrane of duct and acinic cells. Higher beta-catenin index rates were seen mainly in salivary gland ducts and in ductal structures in the adenomas and carcinomas in pleomorphic adenomas. There was protein loss in pleomorphic adenomas and cytoplasmic accumulation in carcinoma in pleomorphic adenomas. CONCLUSIONS: The present study showed participation of the loss of beta-catenin adhesion molecule in the development of pleomorphic adenoma, and that the cytoplasmic accumulation of the molecule takes part in the malignant transformation of the pleomorphic adenoma into carcinoma in pleomorphic adenoma.

Carcinoma basocelular múltiplo e metastático concomitante a sarcoma pleomórfico e metástatico em área de linfedema crônico - Relato de caso

Chronic lymphedema presents as interstitial fluid retention due to a failure in the lymphatic system drainage. The affected region becomes more vulnerable immunologically and predisposed to the onset of neoplasms. Basal Cell Carcinoma is the most common sort of neoplasm, nevertheless it rarely metastisizes. Sarcomas are malignant mesenchymal neoplasms, locally aggressive, which can spread. Here is reported an infrequent case of multiple basal cell carcinoma, synchronous to a poorly differentiated pleomorphic sarcoma, both spreading to lymph nodes and arising from tissue compromised by chronic lymphedema. © 2012 by Anais Brasileiros de Dermatologia.
