To the Editor.—
This letter describes a patient who came to our clinic and whose condition posed an interesting gamut of differential diagnostic possibilities. This case again points out the importance of a good clinical history.
Report of a Case.—
In August 1976, a 13-year-old girl came to the Dermatology Clinic (Fort Sam Houston, Tex) complaining of large "spots" on her trunk. The eruption had begun approximately three months before and involved only the skin over the lumbosacral area. The lesions had progressed, spreading outward around the trunk, and were appearing on the lateral borders of her abdomen.There were multiple solitary and grouped macules 4 to 5 cm in diameter with neither a palpable nor scaly border that were limited to the nonsun exposed area (Fig 1).Initial differential diagnoses included erythema dyschromicum perstans, gyrate erythema, tinea versicolor, inactive fixed drug eruption, leprosy, pinta, and poikiloderma.
