To the Editor: The incidence of nontuberculous mycobacterium (NTM) lymphadenitis appears to be rising, likely because of improved diagnostic techniques. Mycobacterium avium-intracellulare is the most common etiologic agent of NTM lymphadenitis in children (1,2). Newer diagnostic methods, including DNA sequencing, have identified cervical adenitis secondary to other slow-growing species (M. lentiflavum, M. interjectum, and, most recently M. florentinum in 2005) (3–6). We report a case of acute cervical lymphadenitis caused by M. florentinum in a child and briefly describe 4 other patients, both children and adults, with positive culture growth. These results suggest that M. florentinum infection is more widespread than previously appreciated.

A previously healthy girl, 3 years of age, came to our outpatient clinic with 2 months of bilateral cervical lymph node enlargement preceded by low-grade fevers for a few days. She had previously received clindamycin for 10 day without improvement. A tuberculin skin test showed 10 mm of induration, and results of a chest radiograph were negative. Both parents were from El Salvador, but the child was born in the United States and had never traveled abroad.
