Sertoli cell tumor of the testis. Report of a case

OBJECTIVE: To describe an additional case of Sertoli cell testicular tumor. Although more cases have been reported in the world literature, only one case with bilateral involvement has been described in the Spanish literature over the last 18 years. METHODS: A 34-year-old male consulted for a testicular mass which he had detected a few weeks earlier. US and CT evaluation disclosed a tumor in the right testis and no evidence of metastasis. The patient underwent right radical orchidectomy via the inguinal approach and insertion of a testicular prosthesis. RESULTS: Histopathological analysis of the surgical specimen disclosed a Sertoli cell testicular tumor. Patient control follow-up at 3 and 9 months postoperatively showed no changes in tumor markers or CT findings. CONCLUSION: The benign or malignant nature of Sertoli cell testicular tumor is currently defined by the presence or absence of metastasis, although there are histopathological criteria that might indicate a certain degree of aggressiveness.
