Molluscum contagiosum arising in a melanocytic congenital nevus.

Molluscum contagiosum within a congenital melanocytic nevus has rarely been reported. We report a 6-year-old child with molluscum contagiosum infection arising within an intermediate melanocytic congenital nevus of the thigh, associated with itching and occasional bleeding. Dermoscopy lead to the correct diagnosis, but histologic confirmation with shave biopsy was performed to reassure the parents and allow mechanical removal of the lesions using curettage.
