Clinical course of a patient with relapsed PB leprosy. An 89-year-old male relapsed PB patient, who was first treated for leprosy over 50 years prior with chaulmoogra oil, promin and dapsone (diaminodiphenyl sulfone, DDS), was examined. He was diagnosed with lung tuberculosis and treated with streptomycin (SM), isoniazid (INH) and para-aminosalicylic acid (PAS) from 1957 to 1962. In December 2004, he complained of facial numbness and received rifampicin (RFP, 600 mg) once per month and 75 mg of dapsone daily for 6 months. In April 2012, he had three skin lesions, annular erythemas, with loss of sensation in the thighs and again received rifampicin (600 mg) once per month and 75 mg of dapsone daily for 12 months
