EMERGENCE OF LEPROSY IN A PATIENT WITH MYCOSIS-FUNGOIDES

A patient with mycosis fungoides that had progressed to tumor stage re sponded to chemotherapy and electron beam treatment, but 6 years later a peripheral neuropathy, extensive plaques, erythroderma, and enlarge d pinnae containing acid-fast organisms developed while he was being t reated with photopheresis. The skin lesions cleared with administratio n of rifampin and dapsone, but a reversal reaction biopsy specimen sho wed features of both mycosis fungoides and leprosy. This case raises t he question of whether there may be an association between mycosis fun goides and leprosy.
