Pityriasis rosea, is an acute self-limiting papulosquamous inflammatory disorder. It usually starts with a herald patch on the trunk and proximal extremities, followed by scaly oval patches that give them a “Christmas tree” appearance. The lesions may be associated with fever a rash. The disease can present as numerous morphologies such as papular, urticarial, lichenoid, and generalized that may be confused with other conditions such as secondary syphilis, seborrheic dermatitis, nummular eczema, pityriasis lichenoides chronica, tinea corporis, viral exanthems, lichen planus, and PR like eruption linked to particular drugs. We report a rare case of polymorphic pityriasis rosea in paediatric age group.
