Abstract

Pityriasis Lichenoides et Varioliformis Acuta (PLEVA) is a rare and benign dermatosis characterized by a generalized polymorphous eruption that begins as reddish-brown macules and papules that evolve to vesicular, necrotic, purpuric, and crusty lesions. We present a 10-year-old boy with a four-week history of a progressively worsening pruritic rash. Laboratory studies were unremarkable. Dermatology evaluation established the diagnosis clinically, and spontaneous resolution occurred within 2.5 months. This case highlights the importance of recognizing PLEVA in children to avoid unnecessary investigations and support accurate diagnosis and management.
