Cytomorphologic Patterns in Calmette Guerin Bacillus Lymphadenitis
Abstract
Objective To study the cytomorphologic patterns of Calmette Guerin bacillus (BCG) lymphadenitis and compare it to those of tuberculous lymphadenitis. Study design A retrospective cytomorphologic study of 136 cases of clinically diagnosed BCG adenitis. All fine needle aspiration smears of lymphadenitis in the age group 2 months to 2 years during a three-and-half-year period were analyzed. Results Three distinct cytomorphologic patterns were seen in 112 cases. They were acid-fast bacilli in a necrotic background (62), granulomas with necrosis (47) and granulomas in a reactive lymphoid background (3). Conclusion The cytomorphologic patterns in BCG lymphadenitis were similar to those seen in tuberculous lymphadenitis; however, an exudative response and high acid-fast bacillus positivity was seen more frequently in BCG lymphadenitis. Moreover, Ziehl-Neelsen staining helped to distinguish these cases from pyogenic abscesses.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
