ObjectiveTo formulate cytologic features for differential diagnosis of basal cell adenoma (BCA).Study DesignThe usefulness of 5 items for a cytologically definitive diagnosis of BCA was examined. The 5 items in 8 BCA and 22 non-BCA cases (adenoid cystic carcinoma [ADCC], basal cell adenocarcinoma, myoepithelioma, pleomorhic adenoma-P and polymorphous low-grade adenocarcinoma) that displayed mimicking cytology were examined cytologically.ResultsThe useful items were < 5.1 mu m in mean of epitbelial nuclear short diameter; mild atypia on definitive diagnosis; stromal cell cluster combining smooth margin surrounding the epithelial cell cluster or containing the epithelial cell cluster; epithelial clusters surrounded by or adhered to a thick, hyalinized smooth margin without stromal cluster; and closely fastened, tight clusters with denser cytoplasm, than ADCC, but an indistinct border, with oval nuclei and no hyaline cells.ConclusionFive items are useful criteria for BCA.
