Three‐dimensional clusters were more prominent in the UEA group. Vacuolar and/or foamy cytoplasm was observed in 71.4% (10/14) of patients with GAS, whereas this finding was rare among those with UEA (2/18). Marked intracytoplasmic neutrophil entrapment was more common in the GAS group (7/14) than in the UEA group (2/18). Intracytoplasmic mucin was present in eight patients with GAS. Nuclei were vesicular in eight patients with GAS, but were homogenous and hyperchromatic in UEA patients. Conspicuous nucleoli were present in nine patients with GAS. Conversely, this finding was rarely observed in UEA patients.</p> </sec> <sec id="dc23304-sec-0004" sec-type="section"> <title>Conclusions</title> <p>The characteristic cytologic findings of GAS include (1) monolayered and honeycomb sheets, (2) vacuolar and/or foamy cytoplasm, (3) intracytoplasmic neutrophil entrapment, and (4) vesicular nuclei with prominent nucleoli.
