Primary Rifampicin Mono-Resistant Tuberculosis of the Cervical, Mediastinal, and Axillary Lymphadenopathy in an Indian Male: A First-of-Its-Type Case

Isolated mediastinal tuberculous lymphadenitis without a parenchymal lung lesion in adults is rare, with an incidence of 0.25-5.8%.…”

Isolated axillary tuberculous lymphadenitis in a Nigerian female: A case report with review of the literature

“…Tuberculous lymphadenitis is relatively common and is second most common extrapulmonary manifestation of TB with the most common location being cervical lymph nodes (5,6,7). Other documented sites of tuberculous lymphadenitis in decreasing order of frequency are supraclavicular, axillary, mesenteric, porta hepatis, perihepatic and inguinal regions (4,8,9). While TB lymphadenitis may be a local manifestation of systemic disease and therefore easy to diagnose, isolated TB lymphadenitis is relatively uncommon, and therefore presents with unique diagnostic challenges.…”
