[Synovial lipoma arborescens].

The synovial lipoma are uncommon articular tumors of unknown origin. We report two cases of synovial lipoma arborescens arisen in a man and a woman respectively 41 and 27 years old. Both had already consulted for a tumefaction progressively increasing in volume. It was accompanied in the first case by a laxity in the knee joint. Radiography and arthroscopy showed an important hyperplasia of the articular synovia. A total synovectomy was performed in both cases. The synovia had a hairy aspect and was extremely thickened. It weighted 1.5 kg in the first case and its section had a fatty aspect. The histological examination confirmed the diagnosis of synovial lipoma arborescens. The observed aspect of the two tumors and particularly their volume, which was very important in the first case are arguments in favor of their tumoral nature.

[Tumors of the ceruminous glands].

Tumors of ceruminous glands, called "ceruminoma" are rare. They arise from the ceruminous glands of the external auditory canal. They realise a group of glandular tumors diversified in histologic pattern and prognosis. Three patients with ceruminous gland tumors are reported: one case of ceruminous adenoma, one case of adenocarcinoma and adenoid cystic carcinoma in the third one.

[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. This offers, further evidence in support of the theory implicating a chronic inflammatory reaction.

[Collagenous enterocolitis. Apropos of a case and review of the literature].

Collagenous enterocolitis is a recent entity of which only two cases have been published. The authors report the association of collagenous colitis and collagenous sprue in a 67-year-old woman. The diagnosis of collagenous enterocolitis is based on the presence of a duodenal collagen deposit with partial villous atrophy associated with collagenous colitis. The symptom appeared one month after non-steroidal antiinflammatory treatment. The authors discuss the role of drug toxicity in the pathogenesis of collagenous enterocolitis.

[Total septate uterus with hemi-vagina and homolateral renal dysplasia].

We report a rare case of uro-genital malformation in 18 years old girl. The malformation associate total septus uteri, hemivagina atretica dextra and homolateral dysplastic kidney. Dysmenorrhea, purulent discharges from cervix and vaginal tumor evocated the diagnosis, which was confirmed by ultrasonography, hysteroscopy and coelioscopy. Therapeutic attitude was total resection of vaginal septus and right nephrectomy. At today, seven cases were published in international literature. In all cases, renal aplasia was reported. Embryologic acknowlegements can't explain this malformation.

[Ileal perforation in 3 cases of Behçet disease].

Digestive manifestations are uncommon in Behçet's disease. The authors reported 3 male patients between 20 and 30 years with Behçet's disease who developed surgical abdomen. Emergency surgical intervention found perfored ileal ulceration. Histological study of resection piece showed mainly intestinal angitis with periphlebitis, venous thrombosis and obliterant endarteritis.

[Anatomo-clinical characteristics of ovarian fibrothecal tumors. 19 cases over 12 years: 1981-1992[].

The quasi-constantly benign nature of fibrithecomas of the ovary has been known for many years. However, there have been very few studies of their incidence and clinical characteristics. The aim of this study, based upon 19 cases of fibrothecal tumours of the ovary operated upon at the Rabta maternity unit during a 12 year period, is to give an idea as to epidemiological factors, diagnostic conditions and treatment methods used among the women studied.

[Malignant rhabdoid tumor of the central nervous system. Apropos of a case with immunohistochemical and ultrastructural studies, and review of the literature].

The authors report a new case of cerebral malignant rhabdoid tumour in an eight year old girl. The diagnosis was confirmed on immunohistochemical and ultrastructural examinations showing cytoplasmic perinuclear inclusions composed of whorled filaments of vimentin. Base on a review of six cases reported in the literature, they analyse the clinical, histological, immunohistochemical and ultrastructural features of this exceptional central nervous system neoplasm. Different histogenetic hypotheses are discussed.

[Colloid cyst of the fourth ventricle. Apropos of a case].

We report a case of a 29 year old patient with a colloid cyst of the fourth ventricule. Colloid cysts or epithelial cysts are exceptional in this site. A common neuroepithelial origin with third ventricule cysts could be explained by similar embryological developments of the prosencephalic and the rhombencephalic roofs. The diagnosis can only be made by histological examination.
