[Mixed germ cell tumor of the ovary with rhabdomyosarcomatous component. A case report].

Malignant germ cell tumors of the ovary are rare representing 3% of all ovarian neoplasms. Hence, they are the most common ovarian malignancy in girls and young women and account for approximately two-thirds of the ovarian cancers that occur in the first two decades of life. Germ cell tumors constitute a heterogeneous group of tumors and are often mixed associating at least two different tumoral components.

[Primary peritoneal yolk sac tumour. A case report].

Yolk sac tumours are rare germinal neoplasms that often arise in ovary and testis. Extragonadal localisations such as mediastinum, retroperitoneum, brain and vagina are uncommon. Primary intraperitoneal tumours are exceedingly rare.

[Isolated primary gastric localization of a mantle cell lymphoma].

Primary mantle cell lymphoma of the digestive tract is uncommon; it rarely involves the stomach and generally manifests as a lymphomatous polyposis. Isolated gastric localization is exceedingly rare. We present a case of a 57-year-old man who presented with a six-month history of atypical epigastric pain.

[Nonalcoholic steatohepatitis: epidemiologic and pathologic study of 9 cases].

Background: Non alcohol steatohepatitis is an acquired chronic hepatopathy frequently of metabolic origin. Histopathologically, it is characterised by a steatosis associated with necrotic inflammatory lesions mimicking alcohol hepatitis. This disease is complicated by cirrhosis in 15 at 30% of cases and by hepatocellular carcinoma in 13% of cases.

[Digestive polyposis. Retrospective study of 20 cases].

Background: Three main polyposis syndromes are transmitted as an autosomal dominant disorder: familial adenomatous polyposis (FAP), juvenile polyposis syndrome (JPS) and Peutz-Jeghers syndrome.

Aim: Evaluate this management of digestive polyposis.

Methods: Our study included 20 patients which were collected in th departements of pathology surgery and garstroenterology of MT Maarmouri's Hospital, Nabeul city.

[Tubo-ovarian actinomycosis ruptured in the sigmoid colon].

Actinomyces is an anaerobic, gram-positive bacteria saprophyte of the oral cavity, lungs, genital and gastro-intestinal tracts. Tubo-ovarian infection is rare. The authors report a case of tubo-ovarian abscess, due to actinomyces ruptured in the sigmoid and diagnosed in a 30-year-old woman using an intra-uterine device for more than 5 years.

[Digital tuberculous revealed by trauma].

Tuberculous dactylitis is an uncommon condition which is particularly difficult to differentiate from other lesions, particularly tumors. Diagnosis must be confirmed by histology and/or bacteriology studies. We report the case of a 64-year-old diabetic woman who consulted for a painful tumefaction on her fourth finger of the left hand which had developed after minimal trauma.

[Sarcoid-like necrotizing granulomatosis. A case report].

Necrotizing sarcoid granulomatosis is a rare granulomatous pulmonary angeitis that was first described by Liebow in 1973. We report the case of a 36-year-old woman who was admitted for exploration of chest pain, cough and fever at 39 degrees which had progressed for more than 2 months. Chest X-ray showed several inconstant pulmonary opacities.

[Fibrous inflammatory polyp of the digestive tract. Apropos of 5 cases].

Inflammatory fibroid polyp is a rare benign tumor of the digestive tract. The authors report three cases: two intestinal and one gastric. These cases are of particular interest because of the association ill one case of an intestinal submucosal lipoma with the inflammatory fibroid polyp, and the existence in the gastric case of an inflammatory reaction caused by food debris.
