title: Extensive cutaneous hyperpigmentation caused by minocycline.
abstract: A 65-year-old man had cutaneous hyperpigmentation that had occurred over the previous 2 1/2 years. The hyperpigmentation was extensive and involved the sclerae, nail beds, and total body; the palms and buttocks were spared. Clinical diagnosis was suggestive of hemochromatosis or heavy metal deposition. Histologic and electron microscopic findings were consistent with lysosomal iron deposition. A careful history showed that minocycline was the cause. Its use was discontinued, and after several years the patient's pigmentation is gradually returning to normal.
