Acroma Cutis Postparasitaria. Presented by Dr. Throne.  J. K., a boy, aged 15, had had a brownish, scaly, rash on the trunk, shoulders and arms for some time, which had been diagnosed as tinea versicolor. During the past summer, while in camp, he had been exposed a great deal to sunlight, and he said that following this exposure depigmented spots had developed. When first seen, one month before presentation, he showed small, depigmented areas, resembling leukoderma. There was still some scaling on a few brown areas. The scales from one of these lesions showed Microsporon furfur. The depigmented spots were regaining their pigment and were not scaly.

DISCUSSION  Dr. Abramowitz: I saw a patient of Dr. MacKee's with similar lesions about two years ago. He found Microsporon furfur in the white spots. Dr. MacKee explained the anomalous appearance of the active lesions to the filtering of the radiation causing the normal skin to become tanned and the scaly areas to turn white.
