Abstract
We report a case of paratesticular leiomyosarcoma in an 84-year-old man. The tumor was firm and nodular, and attached to the upper pole of the left testis. Light microscopy showed a sarcoma with numerous mitoses. On electron microscopy tumor cells contained 7 nm. microfilaments, with regular dense bodies, micropinocytotic vesicles and the other hallmarks of smooth muscle differentiation, in addition to prominent pools of glycogen. This case illustrates the value of electron microscopy in the investigation of unusual urological tumors.Keywords
