Basal Cell Adenocarcinoma (BCAC) is a rare malignancy, only accounting for approximately 2% of all salivary neoplasms. Considered the malignant counterpart of basal cell adenoma, it most commonly presents at 60 years of age without gender predilection. Sites of involvement frequently includes the parotid gland, but sites in the minor salivary glands, nasopharynx, buccal mucosa, and tongue have also been reported. Often regarded as an indolent malignancy, BCAC can occasionally cause invasive disease and infrequently, metastatic disease. Among all solid tumors, endobronchial metastases is quite a rare occurrence, contributing to approximately 4% of endobronchial biopsies4. Most common sites of metastases in BCAC include cervical lymph nodes with sparse reports of pulmonary, hepatic and cutaneous involvement5. We present a case of endobronchial metastases from BCAC of the base of the tongue.
