Malignant mixed tumor of salivary origin. A clinicopathologic study of 146 cases

Abstract

A 30‐year Memorial Hospital experience with 146 patients with malignant mixed tumor is reviewed. These comprised 5% of 2,743 patients who were treated for salivary neoplasms from 1939 through 1968. The tumors arose in the parotid gland in 108 patients, submaxillary gland in 23 patients, mucus or so‐called minor salivary glands in 16 patients, and sublingual gland in one. In terms of our total experience, 11% of all submaxillary tumors proved to be of the malignant mixed variety as compared to 6% of parotid tumors and 3% of minor salivary tumors, respectively. Seventy‐one patients (48%) had previously received therapy elsewhere. Results of treatment are presented and the factors which influenced the results are discussed.
