• Pityriasis lichenoides et varioliformis acuta (PLEVA) is commonly thought of as a disease of young adults, yet we identified five cases, involving patients who were 3, 5, 6, 8, and 11 years of age, among 13 000 consecutive specimens submitted to a general dermatopathology laboratory during a 15-week period. The clinical and histologic features of PLEVA in our cases were similar to those reported for adults, except that no lesions were observed on the scalp or mucous membranes of children. A high index of suspicion and biopsy specimens of suspected lesions are often needed to differentiate PLEVA from other papular and crusted eruptions seen in the pediatric age group. These include reactions to arthropods, Gianotti-Crosti syndrome, varicella, and erythema multiforme. Histologically, papular eczema and pityriasis rosea may be misdiagnosed as PLEVA.
