Ii. Adenocarcinomas of the Mixed Tumor Type (Seventy-Four Cases)

Eggers1noted in the literature eighty-seven cases of adenocarcinoma, of the mixed tumor type, of the palate and pharynx. In the Mayo Clinic from 1917 to 1930, inclusive, seventy-four cases have been noted. A correct terminology for these growths has been widely discussed. Eggers and D'Aunoy2favor retaining the term mixed tumor, but since the tumors are adenocarcinomas of a specific type, it seems that they might better be designated as such rather than as mixed tumor, which is not so comprehensive. SITUATION Adenocarcinomas of the mixed tumor type are common in the salivary glands and comprise the typical neoplasm of the parotid and submaxillary region. They are less common in the palate, buccal mucosa, alveolar border, nares, base of the tongue, face, neck, lips, lacrimal gland and larynx.3Growths of the palate are the most common with the exception of those in the salivary glands.2
