The patient was a 36-year-old male with a chief complaint of painless mass in the perineum. An elastic and immobile mass with the tip of thumb finger size was palpable in the left perineum and magnetic resonance imaging (MRI) showed the tumor with high intensity on T2 weighted image from perineum through left scrotum. The tumor was surgically removed and a histopathological study revealed epidermoid cyst.
