Numerous brownish-black pigment granules of an unknown nature are described for the first time in association with leg ulcers. These were observed in skin window studies done on the forearm of a patient with the remarkable history of recurrent ulcers of the ankles for the past 11 summers. Although the clinical and histologic findings were not distinctive, the recurrent nature of the ulceration coupled with the skin window pigment made this case unique. We propose the term "atrophie noir" to describe this condition. It stands in contrast with atrophie blanche in which no pigment is found in the lesion or in the skin window inflammatory exudate.
