Chronic cheek lesions: an unusual manifestation of nontuberculous mycobacterial cevicofacial infection.

The characteristics of nontuberculous mycobacteria cheek lesions in 7 children were reviewed. The lesions usually presented as nontender erythematous nodules and were associated with a positive purified protein derivate tuberculin skin test. Mycobacterium haemophilum was isolated in 4 cases (57%) and Mycobacterium avium complex in 3 (43%). Cytology and imaging were noncontributory. Resolution was prolonged.
