[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.
