TUMORS OF THE SALIVARY GLANDS  MUCOEPIDERMOID tumors of the salivary glands were studied recently by Stewart, Foote and Becker.1 Forty-five tumors of this type were noted in a series of 700 patients with major and minor tumors of the salivary gland, examined at Memorial Hospital for Cancer and Allied Diseases between 1928 and 1943. None of the mucoepidermoid tumors had the structural characteristics of a mixed tumor or of a tumor of the salivary glands.Quattlebaum, Dockerty and Mayo2 observed that 10 per cent of a consecutive series of primary neoplasms of the parotid gland were adenocarcinomas of the cylindroma type. Surgically, these adenocarcinomas generally appeared infiltrative rather than encapsulated, and application of the principle of wide local excision prevented recurrences in 5 of the 21 cases. Pathologically, the appearance of dark-staining epithelial islands and strands, with central honeycombing in a hyaline stroma, was diagnostic. Epithelial mucus was
