Sinonasal Adenoid Cystic Carcinoma with Widespread Symptomatic Bony Metastasis

Adenoid cystic carcinoma is a fairly uncommon salivary neoplasm of the head and neck. These lesions often progress insidiously, and they have a propensity for early perineural spread and bony invasion. Distant metastasis to the lungs is fairly common and is usually fatal. We report a rare case of adenoid cystic carcinoma in a patient who on initial evaluation had widespread bony metastasis but no pulmonary involvement.
