[Carcinoma of Bellini's collecting tubules. Apropos of a case].

Carcinoma of the papillary ducts of Bellini is a rare malignant tumour of the kidney, with a generally unfavourable prognosis because of late diagnosis, often at the state of metastases. The diagnosis is based on pathological examination of the nephrectomy specimen with immunohistochemical study. The role of adjuvant chemotherapy needs to be evaluated.
