Background. The optimal treatment of nontuberculosis mycobacterial cervical lymphadenitis in children has not been established. Until recently, surgical excision was the standard treatment, but the number of reports of successful antibiotic treatment is increasing, which questions whether surgery is the preferred treatment. In this randomized, multicenter trial, we compared surgical excision with antibiotic treatment.

Background. Nontuberculous mycobacterial (NTM) lymphadenitis in children is most often caused by Mycobacterium avium. In a prospective, multicenter trial of the optimal treatment, 23.7% of the NTM cervicofacial lymphadenitis cases in children were caused by Mycobacterium haemophilum. In this article, we describe the epidemiological and clinical features of M. haemophilum cervicofacial lymphadenitis.
