Mature retroperitoneal teratoma in adult [Two cases report and litterature review]

ABSTRACT

Retroperitoneal teratomas are rare tumours in adults. We report two cases of primitif mature retroperitoneal teratoma. The first, a 60-year-old woman was with general fatigue and being treated for acute pyelonephritis. The second patient, 30-year-old woman, presented with 2 years history of right hypochondral pains. The clinical exam found a mass of right hypochondrium. In both cases, the initial diagnosis with sonography and computed tomography suspected a retroperitoneal teratoma. The treatment consisted of a total tumoral excision. The follow-up was simple and no recurrence after 60 and 24 months respectively. The anathomopathologic exam concluded with a teratoma without signs from malignity in both cases. We conclude that teratoma is a rare tumour, which need histological examination to confirm diagnosis and seek an immature composent, sign of malignancy
