Molluscum contagiosum occurring in an epidermoid cyst.
The histological picture of molluscum contagiosum (MC) is well known: the epidermis grows down into the dermis as multiple, closely packed pear-shaped lobules. The epithelial cells of the outermost layers and the horny layer display typical molluscum bodies. In this paper, we describe an unusual case of MC in a cystic lesion. This lesion was probably due to localisation of the MC virus in the ostium of the pilar infundibulum, followed by obstruction and formation of an inclusion cyst.
