Les tumeurs des glandes salivaires : étude anatomopathologique à propos de 105 cas

Abstract: Introduction Les tumeurs des glandes salivaires sont rares et tres variees. Elles representent 3 % de toutes les tumeurs du corps et 6 % de celles de la tete et du cou. Elles sont dominees du point de vue morphologique par leur polymorphisme lesionnel. Ce polymorphisme est encore accru, notamment sur le plan clinique, par la diversite des sieges possibles.

Impact pronostique et thérapeutique de la différenciation neuroendocrine au sein de l’adénocarcinome prostatique: mise au point

Abstract: Le cancer neuroendocrine de la prostate est une variante histologique rare. La differenciation neuroendocrine au sein de l’adenocarcinome de la prostate a recu une attention croissante ces dernieres annees en raison de ses implications pronostiques et therapeutiques. Cette differenciation neuroendocrine est presente au moins dans 10 % de tous les adenocarcinomes prostatiques. Aujourd’hui encore, son impact sur le pronostic et le traitement du cancer de la prostate fait l’objet de controverse. Actuellement, elle est consideree comme un facteur de mauvais pronostic implique dans l’hormonoresistance. Les mecanismes de transition vers l’hormonoresistance sont complexes, et la tumeur evolue dans un microenvironnement. La differenciation neuroendocrine est actuellement consideree comme facteur de mauvais pronostic implique dans cette hormonoresistance. Le traitement de la maladie hormonoresistante associera vraisemblablement plusieurs approches. La comprehension de ces differents mecanismes est la cle du developpement de therapies plus efficaces sur les cancers de la prostate hormonoresistants.

Gliosarcome primitif du cervelet : à propos d’un cas

Abstract: Gliosarcoma is a rare tumor of astrocytic origin. It’s classified by theWorld Health Organization (WHO) as a variant of glioblastoma grade IV. It’s characterised by a gliomatous and a sarcomatous proliferation. Conventionally, this tumor is localized at the supratentorial floor.We report a case of a cerebellar gliosarcoma in a 60 years old man. The radiologic apparence was in favor of glioblastoma and the pathologic examination concluded a gliosarcoma. The evolution was marked by the death of the patient.

Psammocarcinome séreux agressif de l'ovaire : à propos d'un cas et revue de la littérature Serous aggressive psammocarcinoma of the ovary: a case report and review of literature

Abstract: Psammocarcinoma of ovary is a rare serous neo- plasm characterized by extensive formation of psammoma bodies with ovarian stromal invasion. Rarely aggressive with invasion of the peritoneum or intraperitoneal viscera, it is linked to a better prognosis than conventional serous adenocarcinoma. It is characterized by a tumor cells with little cytological atypia and a low nuclear grade. Extensive medlar search showed presence of only 29 cases of psammo- carcinoma of ovary reported till date. A new case of aggres- sive psammocarcinoma of ovary in 65 years old woman is reported.

Rôle du pathologiste dans l'évaluation histopathologique de la réponse à la chimiothérapie néoadjuvante dans le cancer du sein : mise au point Role of pathologists in the histopathological valuation of response to the neoadjuvant chemotherapy in breast cancer: update

Abstract: The neoadjuvant chemotherapy is more and more used in the therapeutic sequence of breast cancer. Several pathologists were interested in cytological and histological effects of chemotherapy on tumoral and nonneoplastic breast tissue and on lymphatic nodes. Histological classifications had been proposed and used in the valuation of these effects. The purpose of this study is to review these classifications and to enlighten the role of pathologists in the histopathological valuation of response to the neoadjuvant chemotherapy in breast cancer.

Tumours of salivary glands in the stomatology and maxillo-facial surgery unit at the university hospital centre —Yalgado Ouédraogo

Abstract: The aim of this study was to contribute to strengthening the efficiency in the treatment of the salivary gland tumours in the Stomatology and Maxillo-facial surgery service at the University Hospital Centre/Yalgado OUEDRAOGO of Ouagadougou. It has been a retrospective and descriptive study covering seven (7) years [January 2006-December 2012] on epidemiology and the treatment of 54 cases of the salivary glands tumours histologically confirmed. Benign tumours (non-malignant tumours were prevalent (61.11% of cases). The annual incidences were 4.71 cases for non malignant tumours and 3 cases for malignant tumours. The average age was 34-45 years for non malignant tumours and 44-33 years for malignant ones. In both groups, the tumour was discovered lately with an average 32-48 months before consulting in case of non malignant tumours and 18-29 months for malignant tumours. The location of non malignant tumours was very often the parotid (42.42%), under mandible gland (27.28%). Malignant tumours very often concerned the parotid (76.18%) and the under mandible gland (14.29%). The histology has revealed that pleomorphic adenoma was the leading type of non-malignant tumours (93.94% of cases) whereas carcinoma was predominant in malignant tumours (80.95% of cases). Long term track keeping was difficult and it has been complicated by the loss of contact with some patients. The low living standard, the time wasted before consulting, limited human resources and therapeutic means constitute handicaps to the treatment in our African context.
