- HPC:154 : Atypical mycobacterium cervical adenitis

Definition: Nontuberculosis mycobacterial cervical lymphadenitis is a relatively common disease in immunocompetent children but a rare disease in immunocompetent adults.

Evaluation of immune competence, including gamma interferon (IFN-gamma) and interleukin-12 (IL-12) signaling, finds no evidence of deficiency in these cases.

Nontuberculous mycobacteria can cause a chronic localized cervicofacial lymphadenitis in immunocompetent children. The recommended treatment is total excision of the affected lymph node.

Mycobacterium avium complex and Mycobacterium hemophilum are isolated in 90% of the cultures (#18787500#).

In most cases, the affected lymph nodes underwent violaceous changes with discharge of purulent material for 3-8 weeks.

Nontuberculous mycobacterium (NTM) is one of the well-known causes of cervicofacial lymphadenopathy in children under 5 years of age.

Children often present with a painless cervical mass that fails to respond to conventional antibiotics.

They are often referred under the suspicion of a neoplasm or bacterial adenitis rather than NTM cervical lymphadenitis.

The lack of systemic symptoms, modest or negative purified protein derivative test and absence of exposure to active tuberculosis are characteristics of NTM lymphadenitis.

The diagnosis usually requires the isolation of pathogen or pathologic proof. Complete excision is the choice of treatment by the majority of authors in the literature.

This not only enables rapid diagnosis but ensures the lowest recurrence rate.

Medical management is sometimes successful when complete resection is impossible or refused.

Atypical (nontuberculous) mycobacterium is an uncommon cause of cervical lymphadenitis in immunocompetent children.

Rarely, this disease progresses to locoregional destruction of the deep structures of the neck including salivary glands.

Types

- Mycobacterium avium intracellulare (Mycobacterium avium complex)
- Mycobacterium haemophilum

Management

Total resolution after surgery alone can be achieved within 6 months in 71% of patients and within 9-12 months in the remainder. At the 2-year follow-up, a skin-colored, flat scar in the region of the drainage is noted. (#18787500#)

Recent reports suggest medical monotherapy as an effective treatment of this disease.
