Adenoid cystic carcinoma of the submaxillary gland

A review of submaxillary gland neoplasms over a 21 year period revealed 15 malignancies and 7 benign tumors. All of the malignancies occurred in females, and 11 of these were adenoid cystic carcinoma. Two of the 11 were found to have infiltrating ductal carcinoma of the breast (1 pre and 1 postdiagnosis of the submaxillary carcinoma) and 3 had benign breast disease. While previous reports have suggested an association of parotid gland neoplasia and breast cancer, this is the first known report of an association between adenoid cystic carcinoma of the submaxillary gland and cancer of the breast. The discussion of adenoid cystic carcinoma of the submaxillary gland emphasizes the increased frequency of this disease in females, its association with breast disease, and also experimental submaxillary gland neoplasia.
