Cervicofacial lymphaden itis caused by nontuberculous mycobacteria (NTM) is an increasingly recogn ized condition in otherwise healthy children\, most commonly between 1 and 5 years of age. It typically presents as a firm\, painless cervical\, sub mandibular\, or parotid mass that slowly enlarges over weeks\, with progre ssive thinning and violaceous discoloration of the overlying skin and\, in advanced stages\, spontaneous fistulization. Although NTM lymphadenitis r emains rare in absolute terms\, several population-based series suggest a rising incidence\, including data from Québec indicating a marked increas e in hospital-based diagnoses over recent decades. This trend underscores the need to refine management strategies that balance cure\, complication risk\, and long-term cosmetic outcomes.
Definitive diagnosis relies on microbiologic confirmation by PCR or culture\, but clinicians frequently rely on a combi nation of clinical presentation\, tuberculin skin testing\, interferon-gam ma release assays\, and imaging to guide initial management. Available the rapeutic options include observation\, systemic antibiotic therapy\, non-e xcisional procedures (fine-needle aspiration\, incision and drainage\, cur ettage)\, and complete or partial surgical excision. Current literature ge nerally supports complete excision of affected lymph nodes as the modality with the highest cure and lowest recurrence rates\, with reported success exceeding 95%\, compared with lower cure rates for antibiotics alone\, ob servation\, or non-excisional interventions. However\, complete excision m ay require extensive dissection in anatomically sensitive regions\, exposi ng children to risks such as facial nerve palsy\, wound infection\, conspi cuous or widening scars\, and contour deformities—particularly concernin g in young children with elastic skin and a long lifetime of scar maturati on ahead.
E merging data suggest that partial excision can achieve comparable clinical resolution in some patients\, raising a critical question: are the periph eral lymph nodes and surrounding tissues routinely removed during “compl ete” excision truly involved by active NTM infection at histopathology\, or does an intact immune system clear residual disease without the need f or maximal surgery? To date\, this specific question has not been systemat ically examined.
This presentation will synthesize current evidence on the epidemiolo gy\, diagnostic pathways\, and comparative effectiveness of medical and su rgical management for pediatric cervicofacial NTM lymphadenitis. It will t hen introduce an ongoing project that correlates the histopathologic statu s (microabscesses\, caseating and non-caseating granulomas) of peripheral tissues with clinical outcomes following partial versus more extensive exc ision. By highlighting this knowledge gap\, the proposal aims to stimulate discussion on whether a de-escalation of surgery—tailored to disease ex tent—could maintain high cure rates while reducing complications and imp roving cosmetic results.
