Intrascrotal Extratesticular Epidermal Cyst / 대한비뇨기과학회지

ABSTRACT

An epidermal cyst, presenting as an intrascrotal tumor, with no relation to the testicles or cord structures, is a rare benign tumor. Their etiology is unknown, but the most widely accepted theory on the histogenesis of testicular epidermal cysts is that they are the end result of a monolayer teratoma arising from germ cells; however, an extratesticular epidermoid cyst is believed to be an abnormal closure of the median raphe and urethral groove. An extratesticular epidermal cyst is normally subcutaneous, and can be localized anywhere along the median raphe, from the distal penis to the anus. To our knowledge, there has been no case reported in the Korean literature. A case of an intrascrotal epidermal cyst is reported in a 44-year-old man.
