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.
Eighty-nine women were examined using a flexible fiberscope and targeted biopsy was performed. Although the specimens were small (4 mm3 in maximum diameter), 80% reliability was obtained when specimens were compared with full curettage.
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 primary malignant melanoma of the rectum seen in an 84-year-old woman. This blackish tumour measuring 3 cm in diameter and situated 8 cm from the anal margin was treated by surgical excision. The patient died during the immediate postoperative period.
The authors report a new case of cerebral medulloepithelioma in a four year old boy. Based on review of twenty cases reported in the literature, they analyse the clinical, histological immunohistochemical, ultrastructural and therapeutic features of this rare nervous system tumour.

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.
