Abstract

Molluscum contagiosum (MC) is a viral infection of skin and mucous membrane commonly affecting the adolescents and young adults. Extensive lesions are usually common in immunocompromised patients. We herein report a rare case of MC in an epidermoid cyst (EC) in a 24-year-old immunocompetent male. The provisional clinical diagnosis was inflammed EC or lipoma. On histopathological examination the lesion displayed a unilocular EC in the deep dermis, the lining of which was infected by MC virus with characteristic inclusions.  The overlying epidermis was absolutely normal having no attachment with the cyst.
