Atypical mycobacterial infection of the head and neck in children: A 5-year retrospective review

Abstract

OBJECTIVE: We review the management of 31 cases of atypical mycobacterial lymphadenitis presenting to a tertiary referral pediatric otolaryngology department between February 2002 and February 2007. STUDY DESIGN: Retrospective case review. SUBJECTS AND METHODS: Cases were identified by using the hospital's correspondence and pathology databases. Demographic and clinical information was collected. Descriptive and nonparametric inferential statistics (SPSS; SPSS Inc, Chicago, IL) were calculated. RESULTS: Four patients were treated conservatively with triple-therapy antibiotics. Twenty-seven underwent surgical excision plus 3 months of clarithromycin postoperatively. Thirteen percent developed nodal recurrence; this appeared to be unrelated to the operation performed (χ8 2 = 5.8, P = 0.69) or the management modality used ( P = 0.35). Patients with previous surgery were more likely to have recurrent infection (χ2 2 = 9.3, P = 0.01). CONCLUSIONS: In our experience, nodal excision plus postoperative clarithromycin remains the best treatment option for most children, although those with limited disease may benefit from combination antibiotic therapy. Previous incision and drainage leads to high recurrence rates after later excision and therefore, heightened awareness of these infections is essential to ensure appropriate early management.
