Tuberculous lymphadenitis (scrofula)
Pediatric AIDS Pictoral Atlas, Baylor International Pediatric AIDS Initiative
An 8-year-old HIV-infected boy with tuberculous lymphadenitis (scrofula). Copious amounts of pus spontaneously drained from this lesion. In an immunocompromised child, other causes of lymphadenitis include infections with gram-positive bacteria, atypical Mycobacterium, and Bartonella henselae (catscratch disease); malignancies such as lymphoma; masses such as branchial cleft cysts or cystic hygromas masquerading as lymph nodes; and adenitis due to HIV itself.
