睾丸類表皮嚢腫の1例

Abstract

A 19-year-old male was seen with the chief con, plaint of painless induration of the left scrotal content. The nodule was located at the middle third of the left testis and the laboratory findings were within normal limits. Enucleation of the testicular cyst was done, since the operative diagnosis was benign testicular tumor. The cyst measured 2.0× 1.8×1.5cm. Histopathological diagnosis was epidermoid cyst of the testis. Twenty-three cases of epidermoid cyst of the testis were collected from the Japanese literature including our case, and some clinical and pathologic findings were presented. Epidermoid cyst of the testis is regarded as a benign lesion, but differential diagnosis of simple epidermoid cyst from other forms of testicular tumor can be accomplished only by careful pathologic examination of multiple sections from the tumor. It is difficult to accomplish at the time of frozen section. On these grounds, orchiectomy for testicular epidermoid cyst is generally accepted as a treatment of choice.
