Phytophotodermatitis in 19 children admitted to hospital and their differential diagnoses: Child abuse and herpes simplex virus infection.

Abstract

Phytophotodermatitis is a non-immunologic cutaneous reaction that can be provoked after contact with plants containing psoralens followed by sun exposure. The purpose of this study is to describe the clinical features of phytophotodermatitis and its differential diagnoses, especially child abuse and herpes virus infection. Nineteen children seen in two county hospitals are described. The 19 children had various cutaneous manifestations, which were mistaken in one patient for child abuse and in one child for herpes simplex virus infection. The doctors' perception is based on the doctors' education. Children are susceptible to contact with psoralen-containing plants followed by sun exposure. Phytophotodermatitis is a difficult diagnosis, which can sometimes lead to the inappropriate investigation of child abuse or herpes simplex virus infection.
