Basal cell adenoma: A diagnostic dilemma on fine needle aspiration cytology
Abstract
Basal cell adenoma (BCA) is a rare neoplasm which is one of the basaloid tumors of salivary gland. Basaloid tumors are the most difficult problem in salivary gland fine needle aspiration cytology (FNAC). There are various benign and malignant tumors such as; cellular pleomorphic adenoma, basal cell adenocarcinoma, adenoid cystic carcinoma, metastatic basal cell carcinoma, metastatic basaloid squamous carcinoma and small cell carcinoma in differential diagnosis. We present a case of BCA, membranous type in a 39-year-old female with right submandibular swelling misinterpreted as adenoid cystic carcinoma (ACC) on FNAC. Diagn.
