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.
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.

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.
The authors report two cases of umbilical endometriosis. Clinical diagnosis is established on menstrual rhythmicity of pain, swelling and bloody discharge. The treatment of choice for umbilical endometriosis is the surgical removal.
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.
The authors report a case of undifferentiated embryonal sarcoma of the liver, observed in a 25 year old man, in whom the diagnosis, established by histological findings, was confirmed at immunohistochemical examinations. The clinical and pathological features of these conditions are discussed.

The authors report a case of liver cell carcinoma arising in Caroli's disease. A review of the literature shows that this association is quite rare. The etiology of the malignant transformation is discussed.
The authors report a case of aspergillus granuloma of the brain, in a 28 year old woman, simulating a meningioma. Preoperative diagnosis of aspergilloma is difficult. However, it may be suspected in a patient who has associated pulmonary and paranasal sinus fungal infection. Peroperatively it may be confused with a brain tumour. The lesions usually are in the frontal lobes. Diagnosis can be made only by surgical biopsy with identification of fungal elements. Granuloma induce a good host response, and a high capacity to elaborate antibodies.
The authors report a case of thyrolipoma in a 50 year old woman, presenting with nodular goitre and tracheal compression. Microscopically, the coexistence of adipocytes and thyroid vesicles within the thyroid nodule is characteristic of this rare tumor. The relationship between this tumor and diffuse thyroid lipomatosis and amyloid goitre are discussed.
The authors report a case of Scrotal subcutaneous dirofilariasis in man for the first time in Tunisia. The diagnosis was established by pathological examination of a biopsy but the identification of the species was not possible. Surgical exeresis of the node was followed by a complete recovery.
