Erythema dyschromicum perstans. A case report.

Erythema dyschromicum perstans (EDP) is an acquired dermatosis characterized by ash gray (ashy dermatosis) or blue macules. It can appear at any ageö but is more common in young adults. Lesions may occur on the neck, chest arms and face, but most frequently on the back. It does not generally lead to subjective complaints, but may rarely cause itching. Diagnosis is made with clinical findings and can be corroborated by histopathological examination. This report describes the case of a 15-year-old female patient diagnosed with EDP and is intended to emphasize the need to include the condition at differential diagnosis.
