The renal cell tumour supposes 1% of the adult's tumors, while the transitional carcinoma has an incidence of 7%. The simultaneous appearance of a carcinoma of renal cells, and a transitional tumour of pelvis in the same kidney, they suppose an exceptional fact not existing but of 30 cases published in the world, presenting an approximate incidence of 0.14% of the pathology renal tumoral. We present a new case of this unusual association that supposes the 4 case indexed in the literature in Spanish.

Primary lymphoma of the breast is a rare entity in the field of oncological medicine and represents <0.5% of all breast malignancies. A definitive diagnosis is obtained by excisional biopsy as the clinical and radiographical presentation is similar to the more common primary breast carcinoma. Unlike primary breast carcinoma, localized radiation therapy is the mainstay of treatment. We report on a case of primary follicular lymphoma of the breast in a 67-year-old Caucasian woman treated with localized radiation as well as coinciding literature review regarding outcomes of different treatment modalities.

El tumor de células renales supone el 1% de los tumores del adulto, mientras que el carcinoma transicional tiene una incidencia del 7%. La aparición simultánea de un carcinoma de células renales, y un tumor transicional de pelvis en el mismo riñón, suponen un hecho excepcional no existiendo más de 30 casos publicados en el mundo, presentando una incidencia aproximada del 0,14% de la patología tumoral renal. Presentamos un nuevo caso de esta inusual asociación que supone el 4 caso referenciado en la literatura en español.

Weekly docetaxel with a short course of estramustine and enoxaparine is active and tolerable in HRPC patients. The observed incidence of thrombosis was lower than previously reported but the association of enoxaparine was not enough to completely prevent the thromboembolic events.
