title: Organ preserving surgery in testicular epidermoid cysts.
abstract: Our experience with 18 patients with simple epidermoid cysts of the testis (monodermal teratoma) is reported. In all patients the tumor was enucleated completely and 2 biopsies of the adjacent parenchyma were obtained for exclusion of associated germ cell cancer, scar or carcinoma in situ. There was no evidence of malignancy in any biopsy specimen. Preoperative evaluation included physical examination, testicular sonography, and determination of alpha-fetoprotein and beta-human chorionic gonadotropin levels. Although epidermoid cyst was strongly suggested by sonography, the ultrasonic appearance was not specific and inguinal testicular exploration was required. In 1 patient multiple epidermoid cysts of the right testis were associated with an adult teratoma containing embryonal carcinoma and choriocarcinoma of the left testicle. To our knowledge no similar case has been described in the literature. Based on our results and our experience, we consider tumor enucleation and biopsy of the adjacent parenchyma as adequate treatment for the benign epidermoid cyst. The literature concerning organ sparing surgery in testicular epidermoid cysts is reviewed.
