title: [Testicular epidermoid cyst: orchiectomy or enucleation resection?].
abstract: Our experience with 18 patients with simple epidermoid cysts of the testis is reported. In each patient the tumour was enucleated completely and two biopsies of the adjacent parenchyma were obtained for exclusion of associated germ cell cancer, scars or carcinoma in situ. There was no evidence of malignancy in any of the biopsy specimens. Preoperative evaluation included physical examination, testicular sonography, and determination of AFP and hCG serum levels. Although epidermoid cyst can be strongly suspected on sonography the ultrasound appearance is not specific, and inguinal testicular exploration was required in these patients. In 1 patient multiple epidermoid cysts of the right testis were associated with an adult teratoma containing embryonal carcinoma and choriocarcinoma of the left testis; no similar case has been described in the literature. On the basis of our results and experience we consider tumour enucleation and biopsy of the adjacent parenchyma to be adequate treatment for benign epidermoid cyst. The world literature concerning organ-sparing surgery in testicular epidermoid cyst is reviewed.
