Extraskeletal Ewing sarcoma of the abdominal wall.

Ewing sarcoma is most commonly a bone tumour which has usually extended into the soft tissues at the time of diagnosis. Exceptionally, this tumour can have an extraskeletal origin. Clinical or imaging findings are non-specific and diagnosis is based on histology. We report a case of an extraskeletal Ewing sarcoma developed in the soft tissues of the abdominal wall in a 35-year-old woman who presented a painful abdominal wall tumefaction. Ultrasongraphy and computed tomography showed a large, well-defined soft tissue mass developed in the left anterolateral muscle group of the abdominal wall. Surgical biopsy was performed and an extraskeletal Ewing sarcoma was identified histologically.

[Survival and prognostic factors of colorectal adenocarcinoma: analytic multifactor review of 150 cases]. / Survie et facteurs pronostiques des adénocarcinomes colorectaux: étude analytique uni- et multifactorielle de 150 cas.

INTRODUCTION: Prognostic factors have a pivotal role in clinical oncology. They are helpful in the selection of treatment; provide insights into the disease process and the therapic response. The number of possibility useful prognosis factors in the colorectal cancer is large. This study attempts to observe the survival of colorectal adenocarcinoma and to find prognostic factors and other variables potentially associated with outcome of colorectal adenocarcinoma. MATERIAL AND METHODS: It's a retrospective study based on 150 patients with colorectal adenocarcinoma from 1990 to 2002. There were 150 patients aged of 58 years (median 61 years) with 1.4 sex-ratio. 84 patients had colon adenocarcinoma and 66 patients had rectal adenocarcinoma. In histological exam the adenocarcinoma was well differenced in 69 cases (46%), and undifferentiated in 17 cases (18, 3%). RESULTS: Locoregional extension was found in 18 cases and metastatic extension in 45 cases with hepatic metastasis in 37 cases and pulmonary metastasis in 8 cases. There were 6 cases of peritoneal localized carcinosis and 6 cases of ovary metastasis. There were 6 patients (4%) Dukes stage I TNM, 61 stage II (40, 7%), 51 stage III TNM (34%) and 32 patients stage IV TNM (34%). All patients had surgical curative resection associated with adjuvant chemotherapy in 60 cases of colon adenocarcinoma and preoperative radiotherapy in 33 cases of rectal adenocarcinoma. After a follow up of 46 months, 52 patients was died (10 operative mortality), 35 patients were lost of view and 63 patients were still alive at the point date. Median survival was 20 months with 95% confidence interval: (4, 2-7, 8). Overall one year and 5 years survival were respectively 92,8% and 26,3%. Various prognostic factors had been identified through univariate (Kaplan-Meier) then multivariate (Cox) analyze. In addition to the clinical factors, we found of significant prognostic value undifferentiated adenocarcinoma and an elevated value of serum carcinoembryonic antigen>5 ng/ml.

Intrahepatic Osler's disease: report of two cases and review of the literature.

Osler-Weber-Rendu disease is a hereditary vascular disease with multiple manifestations. The liver is involved rarely. Vascular abnormalities include telangiectasis and arteriovenous fistulas, sometimes associated with fibrosis and cirrhosis. Hepatic arteriovenous shunting may include secondary portal hypertension, reduced liver function and high cardiac output. Two cases of Osler-Weber-Rendu disease with extensive hepatic arteriovenous fistulation were described in detail and we report on their clinical features. In the first patient, treatment was symptomatic since liver transplantation is not indicated because the patient was asymptomatic. Embolization treatment of hepatic arteries was indicated in the second patient because he had biliary disease and recurrent cholangitis secondary to vasculo-biliary shunts. Therapy with arterial embolization, banding, or ligature of hepatic arteries is still limited and provides unsatisfactory long-term results. Liver transplantation offers now another therapeutic option for patients with intrahepatic high shunting and secondary pulmonary hypertension.

[Intracerebral chondroma. Apropos of a case]. / Chondrome intra-cérébral. A propos d'un cas.

A rare case of intracerebral chondroma in a 45 years old man with a long history of headache and recent epilepsy is presented. Microscopic examination of the resected tumor revealed that it was chondroma.
