Epidermoid Cyst of Forearm In A Young Male Showing Classical Pseudotesticular Pattern.

Abstract

Epidermoid cysts are benign, slow-growing lesions commonly seen in young adults. This case report describes a 21-year-old male with a painless, progressively enlarging nodule on his right forearm. USG showed Presence of an epidermoid cyst characterized by a pseudotesticular pattern. The lesion was well-defined with a homogeneous echotexture, resembling testicular tissue. There was no significant internal vascularity on color Doppler imaging, further supporting the benign nature of the cyst. The surrounding tissues appeared normal with no signs of inflammation or other abnormalities. Clinical examination revealed a firm, mobile nodule with a central punctum. The cyst was excised under local anesthesia, and histopathology confirmed the diagnosis of an epidermoid cyst. The patient had an uneventful recovery with no recurrence at follow-up. This case underscores the effective management of epidermoid cysts through complete surgical excision.
