Abstract

Idiopathic Eruptive Macular Pigmentation (IEMP) is a rare conditioncharacterized by asymptomatic macular pigmentation. We present a casereport of an 8-year-old white girl presenting with diffuse brown non-scalymacules on neck, chest, back, arms and legs with no other symptoms. Theonset was abrupt and no suspicious contact with similar rash is stated. Patienthas history of asthma; however, she had no recent dermal inflammatoryincident. Family history is negative. With clinical suspicion of Lichen Planus(LP), a 4-mm punch biopsy of skin lesion was performed. The histopathological examination revealed increased superficial dermal melanophages withpigment incontinence with no epidermal changes and no increased mast cellcount, consistent with IEMP. No definite features of LP, LP variant or LPPigmentosus were identified. Since IEMP is a self-limiting disease, shereceived no treatment; however, parents were advised to follow up in case ofthe eruption of new lesions. After one year of follow up, the pigments hasdecreased marginally; which is consistent with natural course of IEMP.
