Dystrophic calcinosis cutis secondary to intrauterine herpes simplex.

A neonate had numerous positive skin cultures for herpes simplex virus (HSV) as well as associated abnormalities strongly suggestive of a maternal intrauterine infection. In addition, he was noted to have dystrophic calcinosis cutis involving the back and buttocks. We believe the dystrophic calcinosis cutis occurred as a consequence of the HSV infection.
