title: Fine needle aspiration cytology of basal cell adenoma of the salivary gland.
abstract: OBJECTIVE
  To formulate cytologic features for differential diagnosis of basal cell adenoma (BCA).
  
  
  METHODS
  The 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, pleomorphic adenoma and polymorphous low-grade adenocarcinoma) that displayed mimicking cytology were examined cytologically.
  
  
  RESULTS
  The useful items were < 5.1 microm in mean of epithelial 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.
  
  
  CONCLUSIONS
  Five items are useful criteria for BCA.
