pityriasis lichenoides

a rare, self-limited skin disease with discolored papular lesions, encompassing a spectrum from pityriasis lichenoides et varioliformis acuta to pityriasis lichenoides chronica.

pityriasis lichenoides

A rare idiopathic, self-limiting dermopathy with clinical presentations ranging from papular lesions of acute onset that rapidly evolve into pseudovesicles and central necrosis (pityriasis lichenoides et varioliformis acuta—PLEVA) to small, scaly, benign-appearing papules (pityriasis lichenoides chronica), to a rare febrile ulceronecrotic variant of PLEVA with high fever and marked constitutional symptoms. Lesions may self-involute and resolve completely over weeks, or new lesions may appear in crops, waxing and waning spontaneously for months to years thereafter.

Management
Antibiotics—tetracycline, erythromycin, corticosteroids.
