(a) Tuberculous lymphadenitis showing many well-formed epithelioid cell granulomas (Giemas ×100) with Caseating tuberculous lymphadenitis (left lower inset, Giemas ×400) and granuloma along with numerous neutrophils (right upper inset PAP, ×400). (b) Acid fast bacilli (arrows) in a case of tuberculous lymphadenitis (ZN ×1000). (c) Demonstration of bacilli through autofluorescence technique on Papanicolaou stained smears (Pap ×400).
