A 45-year old human immunodeficiency virus-positive male; agricultural laborer presented with a swelling over right elbow, right hand deformity, generalized itching and recurrent vesicles overthe perinasal area. Clinical and investigational findings were consistent with mononeuritic type of Hansen's disease with right sided silent ulnar nerve abscess, partial claw hand. CD4+ count of the patientwas 430 cells/cmm. This patient also hadherpes simplex labialis, with HIV-associated pruritus. To the best of our knowledge such an atypical presentation has not been reported earlier.
