Salivary duct carcinoma (SDC) is a recently described highly malignant tumor, seen most commonly in the parotid gland & occurs in the 6th and 7th decade of life. Rarely, it occurs in the minor salivary glands. The case is presented because of its rare occurrence and unusually presenting as a swelling predominantly involving the maxillary bone. The tumor bears histological homology with breast carcinoma, prostatic carcinoma and sweat duct carcinoma.
