Basal cell adenoma is a rare type of monomorphic salivary adenoma most commonly involving the parotid gland. Cytology of basal cell adenoma closely mimics many other benign and malignant basaloid neoplasms. Cytological features of membranous basal cell adenoma simulate adenoid cystic carcinoma in fine needle aspiration cytology (FNAC) smears. Here, we are presenting a rare case of cytodiagnosis of membranous basal cell adenoma of parotid gland in an elderly lady, which mimicked adenoid cystic carcinoma on FNAC. We discuss the cytomorphology of this rare case with an emphasis on cytological difference between membranous basal cell carcinoma and adenoid cystic carcinoma as well as other basaloid neoplasms.
基底细胞腺瘤是一种罕见的单形性腺样瘤，最常累及腮腺。基底细胞腺瘤的细胞学特征与许多其他良性和恶性基底样肿瘤极为相似。在细针穿刺细胞学（FNAC）涂片检查中，膜性基底细胞腺瘤的细胞学特征类似腺样囊性癌。在此，我们报告一例老年女性腮腺膜性基底细胞腺瘤的罕见细胞诊断病例，该病例在FNAC检查中酷似腺样囊性癌。我们讨论了这一罕见病例的细胞形态学，重点阐述了膜性基底细胞癌与腺样囊性癌以及其他基底样肿瘤在细胞学上的差异。
