Molluscum contagiosum, Sebaceous cyst, Immunocompetent


Molluscum contagiosum (MC) is a viral infection of the skin and mucous membrane that usually presents as umbilicated, flesh colored dome shaped papules and are mostly self-limiting in immune competent individuals, though extensive lesions and atypical presentations may be observed in the immune-compromised. Here we present an extremely rare incidence of MC presenting as a sebaceous cyst (SC) in the post auricular region, in a fourteen year old immune-competent male child. Though few incidences of MC within an epidermal cyst (EC) have been reported, this infection primarily presenting as a cystic lesion simulating a SC in an immune competent individual is extremely rare. Imaging findings were consistent with subcutaneous cyst in keeping with a SC, which was then treated by surgical excision. Histopathology of the surgically removed lesion revealed a cyst lined by stratified squamous epithelium containing numerous molluscum bodies. No further treatment was required since this was the only intact lesion present.
