Fine‐needle aspiration cytology diagnosis of tuberculosis

Abstract

Fine-needle aspiration cytology of lymph nodes and extranodal swellings in 160 cases showed granulomatous reaction with or without caseation necrosis in 83%. The material was acellular or predominantly composed of necrotic material, polymorphs, and lymphocytes in 17%. The age of the patient ranged from 1.5 to 72 yr. The male to female ratio was 1:1.3. Acid-fast bacilli (AFB) could be demonstrated in 40.6% of cases. In cases associated with cellular reaction and necrosis, AFB positivity was 50.0%, while it was 66.7% in cases with acellular necrotic material. Diagn Cytopathol 1987;3:13–16.
