Prostate tumors represent the most frequent malignancy in men. Epithelial lesions are frequent, whereas malignancies of mesenchymal origin represent only 1-2 % of all prostatic malignacies. They are little known, mostly those of stromal origin. A case of a 77 year- old man with prostatic stromal sarcoma is presented to whom partial exeresis is performed. The tumor practically occupies the totality of the pelvic abdominal cavity, and it had a diameter of 35 cm and a weight of 3 800 g. Histologically, it was recognized as prostatic sarcoma although an evident link with this organ was not found during the transoperatory. The clinical behavior of these tumors, based on the little cases described in the literature, is practically unknown and its preoperative diagnosis becomes difficult. The patient presented with weight loss, he had no pain, hematuria, or obstructive symptoms.

Palabras clave : sarcoma; prostatic stroma; prostate.
