[Adenomatoid tumors of the epididymis and testicle: report of 9 cases and bibliographic review].

BACKGROUND To report the cases of adenomatoid tumors seen at Hospital Universitario La Paz in the last 15 years. METHODS A clinical, pathological, and surgical study was conducted of males with testicular or paratesticular tumors with a histological report of adenomatoid tumor. RESULTS Among the nine cases studied, seven had paratesticular and two intratesticular adenomatoid tumors. Treatment of choice was mass removal for epididymal tumors and orchidectomy for intratesticular tumors. CONCLUSIONS Adenomatoid tumors are uncommon benign neoplasms of a possible mesothelial origin. Because of their benign nature, the treatment of choice is local excision (conservative surgery), but orchidectomy was performed in two cases due to tumor location.
