Intrascrotal epidermoid cyst: report of two cases

A 70-year-old man and a 52-year-old man each presented with a painless extratesticular, intrascrotal mass. Magnetic resonance imaging revealed a cystic mass and was the most useful modality for the diagnosis. Complete excisions were performed, and the lesions were histologically diagnosed as epidermoid cysts. Intrascrotal, extratesticular epidermoid cysts are uncommon lesions believed to be teratomas or the result of abnormal embryological closure of the median raphe. However, it is difficult to explain the etiology of some masses by either of these mechanisms.
