Pityriasis Lichenoides et Varioliformis Acuta (PLEVA) is an uncommon, inflammatory skin illness typified by erythematous papules that can mimic various dermatological and systemic conditions, making diagnosis difficult. We describe a case of a young adult who presented with generalized erythematous macules and crusted patches across the trunk that progressed to the extremities and scalp. A provisional diagnosis of guttate psoriasis with PLEVA as the differential diagnosis was made after a thorough history and examination. Further evaluation and skin biopsy confirmed the diagnosis of PLEVA through histopathological examination. The lesions subsided after two months of treatment with oral and topical corticosteroids.
