Tumor de células de Sertoli maligno

Abstract

We report a new case of Sertoli cell testicular tumor with malignant characteristics. 77 year-old male patient, suffering a general wasting syndrome presenting with a left solid testicular mass with the diagnosis of malignant Sertoli cell tumor after orchyectomy, without local, regional or distant dissemination, and a benign outcome after 18 months of follow-up. Sertoli cell tumor or androblastoma is classified as non-germ cell tumor derived from the stroma of the sexual cords. There are three types depending on its cellular composition: calcified big cell, sclerotic cell, and the most frequent of all, the classic type. Being the Sertoli cell testicular tumor rare, its malignant type is even rarer, accounting for not more than 10% of all. Despite the pathological characteristics related to malignancy, its posterior behaviour is unpredictable and not much known, the some than follow-up and treatment, because it is not sensible to cytostatic drugs. The existence of metastases continues to be the only valid parameter with prognostic value.
