Idiopathic Eruptive Macular Pigmentation Involving the Distal Extremities: A Case Report

Abstract

Idiopathic eruptive macular pigmentation is a disorder of pigmentation found in children and adolescents. It typically manifests as nonconfluent tan to brown macules involving the neck, trunk, and proximal extremities. We report the case of a 6-year-old girl with an atypical presentation involving the distal extremities. Histopathology confirmed the subtle increase in pigmentation of the basal layer of the epidermis. Treatments are largely ineffective. The condition is generally self-limited over months to years, thus treatment is unnecessary.

Progression of Idiopathic Eruptive Macular Pigmentation in a Girl from Childhood to Adolescence: Case Report and Literature Review

“…Neodymium‐yttrium‐aluminum‐garnet (1,064 nm) and Q‐switched ruby (694 nm) lasers used in a single case were ineffective . Topical steroids, hydroquinone, and tretinoin were also not beneficial except in one case . In our case, we tried oral transamic acid and topical triple‐combination cream without an apparent response.…”

Idiopathic eruptive macular pigmentation in a pediatric patient and a review of the literature

“…Morphology included tan to dark brown as a descriptor in 33 cases, macules in 33 cases, and patches in 6 cases. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Biopsy 15 The underlying pathogenesis for IEMP remains unclear and several theories have been proposed. There may be a hormonal influence as it tends to present in children and adolescents most commonly during puberty.…”
