NEYRO, Silvina E et al. Peripheral tuberculous lymphadenitis in pediatrics: 16 years of experience in a tertiary care pediatric hospital of Buenos Aires, Argentina. Arch. argent. pediatr. [online]. 2018, vol.116, n.6, pp.430-436. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2018.430.

Extrapulmonary tuberculosis accounts for 15-20 % of all clinical presentations of tuberculosis. Peripheral tuberculous lymphadenitis is the second most common presentation of extrapulmonary tuberculosis in children, after pleural tuberculosis, in Argentina. We analyzed 92 patients with peripheral tuberculous lymphadenitis seen at the Department of Tisiology of Hospital de Niños "Dr. Ricardo Gutiérrez" between August 2000 and September 2015. The patients' mean age was 8.7 ± 5 years. Nodal sites corresponded to single peripheral (31.5 %), multiple peripheral (20.6 %), and peripheral associated with deep nodes (47.8 %). Cervical lymph nodes were the most common site of involvement (80 %). In 80 % of patients previous antibiotic therapy had been administered, without response. The tuberculosis source was known in 56 %; 69 % had a positive tuberculin skin test; and 54 %, a pathological chest X-ray. Tuberculosis treatment was started on all patients based on clinical criteria, exposure and/or positive tuberculin skin test, prior to microbiological or histological confirmation. The clinical course was either healing (81.5 %), referral to a facility near home (8.7 %) or dropout (8.7 %). One patient died.
