Abstract

Idiopathic eruptive macular pigmentation is a relatively rare disease entity characterized by asymptomatic, pigmented macules involving the face, neck, trunk, and proximal limbs. We report a case of idiopathic eruptive macular pigmentation in a 19-year-old female patient, who presented with brown colored macular pigmentation which started appearing at the age of seven. The skin lesion gradually increased in numbers and in size over trunk, neck and face without any history of prior inflammation or drug intake. The lesion showed no improvement with chemical peeling or laser therapy. The histologic study revealed an increased epidermal basal layer pigmentation and many melanophages in the papillary dermis. The patient was treated with 2% hydroquinone for six months on the face to disclose satisfactory improvement.
