ORGAN-PRESERVING SURGERY IN TESTICULAR EPIDERMOID CYSTS

Our experience with 18 patients with simple epidermoid cysts of the te stis (monodermal teratoma) is reported. In all patients the tumor was enucleated completely and 2 biopsies of the adjacent parenchyma were o btained for exclusion of associated germ cell cancer, scar or carcinom a in situ. There was no evidence of malignancy in any biopsy specimen. Preoperative evaluation included physical examination, testicular son ography, and determination of cu-fetoprotein and beta-human chorionic gonadotropin levels. Although epidermoid cyst was strongly suggested b y 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 conta ining embryonal carcinoma and choriocarcinoma of the left testicle. To our knowledge no similar case has been described in the literature. B ased on our results and our experience, we consider tumor enucleation and biopsy of the adjacent parenchyma as adequate treatment for the be nign epidermoid cyst. The literature concerning organ sparing surgery in testicular epidermoid cysts is reviewed.
