You are correct. Histologic exam revealed a dense neutrophilic infiltrate of the eccrine cells consistent w/ palmoplantar eccrine hidradenitis. PEH is an uncommon dz, characterized by erythematous violaceous papules and nodules of abrupt onset on the soles of otherwise healthy children; palms may rarely be involved. The nodules usually appear after intense physical activity and are so painful that they lead to walking impairment. PEH has a self-limiting course; abstention from physical activity and bed rest alone are the best tx, leading to complete regression of lesions in about a week.
