Minocycline-induced hyperpigmentation in leprosy.

Abstract

A 36-year-old man was treated with dapsone, rifampicin and clofazimine for borderline lepromatous leprosy. After 9 months, his leprosy plaques became progressively more red and after 23 months, the clofazimine was stopped and he was given minocycline instead. Six weeks later, he developed blue-black pigmentation in his leprosy lesions. The histology was consistent with minocycline-induced hyperpigmentation. This is the first report of minocycline-induced pigmentation in leprosy. We suggest it is important to consider this side-effect before the administration of minocycline in leprosy, particularly if it is prescribed in place of clofazimine.
