Basal cell adenocarcinoma (BCAC) of salivary glands is uncommon low‐grade malignancy. Only 19 cases of preoperative cytology were reported up to date. We present here a new case of BCAC arising in the minor salivary gland. Tumor was composed of clustered or isolated roundish, dark cells with small and regular nuclei. Chromatin was dusty with small nucleoli. Cytoplasm was gray and scant. Clusters showed typical and characteristic basal architecture with peripheral palisading neighboring eosinophilic basal membranes. A false‐negative diagnosis of basal cell adenoma was rendered. In our knowledge it is the first cytological description of BCAC arising in the minor salivary gland.
