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.

The clinical, follow up and diagnostic features of a case of chemodectoma (paraganglioma) of the orbit are reviewed. 30 cases are reported in the literature. Chemodectoma may arise in any area of the body where non chromaffin paraganglion structures are situated. These are localized in the orbit of the chimpanzee but not in the orbit of man. Malignant behavior of chemodectoma has been a controversial subject, with most authors considering them to be benign tumors. Some authors have diagnosed locally recurrent and infiltrative tumors as malignant. The authors report one case of chemodectoma of the orbit. A 5 year old child has had right exophthalmos. She was treated by tumorectomy. The follow-up is marked by recurrence of the tumor and infiltration of the right hemi-face.
