title: Periorbital hyperpigmentation and erythema dyschromicum perstans.
abstract: Erythema dyschromicum perstans is a rare idiopathic dermatosis characterized by ash-grey, well-demarcated skin lesions, which may involve the face. We describe an 8-year-old girl with erythema dyschromicum perstans presenting as bilateral acquired periorbital hyperpigmentation. The changes seen on histologic study of a skin biopsy specimen were consistent with the clinical diagnosis. The various causes of periorbital hyperpigmentation and characteristics of erythema dyschromicum perstans are reviewed.
