Submandibular Gland Basal Cell Adenoma.

Basal cell adenoma (BCA) is a rare benign epithelial tumour of the salivary gland majorly involving the parotid gland, and rarely the submandibular gland. We describe a rare case of BCA of the submandibular gland diagnosed preoperatively using fine needle aspiration cytology in a 60-year-old woman presenting with painless submandibular swelling. The surgery went uneventfully, and the histopathological examination confirmed the diagnosis. BCA can be accurately diagnosed only through histological observations due to its resemblance to various benign and malignant salivary and non-salivary gland tumours, which are difficult to biopsy.
