Septal perforation secondary to Mycobacterium kansasii infection.

We report the first recorded case of a septal perforation caused by Mycobacterium kansasii. This atypical mycobacterium is finding increasing prevalence with the increasing incidence and longevity of human immunodeficiency (HIV) infections. Cases of chest infection, sinusitis, septic arthritis, osteomyelitis, pericarditis, brain abscess, cutaneous and oral lesions have all now been reported. This discovery represents a rare but important differential in the aetiology of septal perforation.
