Clinical-Pathologic Studies on Salivary Gland Tumors
A statistical analysis was made on 40 cases of salivary gland tumors diagnosed at Seoul Paik Hospital, Inje Medical College from 1972-1980. 1) Histological classification revealed benign pleomorphic adenomas in 31 cases(77.5%), adenocarcinoma: 3 cases(75 1(2.5%), acinic cell adenocarcinoma; 1(2.5%), malignant pleomorphic adenoma : 1(2.51(2.5%), Iymphangioma, 1 (2.5%). 2) Mean age of patients with salivary tumor was 43.2 years and mean age for benign pleomorphic adenoma was 37.9 years. Mean age of carcinoma patients was 57.2 years. Overall sex distribution of salivary gland tumors was 25 cases for male and 15 cased for female. On benign pleomorphic adenoma, male/female was 18/13. 3) Distribution of the site is as follows: Parotid gland in 15 cases(37.5%), sublmandibular gland in 14 cases(35%), minor salivary gland in 10 cases(25%). Among benign pleomorphic adenoma, submandibular gland was the most favorite site with 13 cases(41.9%) out of 31. Among 7 cases of malignant lesions including 1 case of malignant pleomorphic adenoma, 4 cases occurred at the Parotid gland. 4) Mean size of the salivary gland tumors was 3.5 cm. Average size of benign pleomorphic adenoma was 3.4 cm including 1.7 cm for minor salivary gland and 4.0 cm for major salivary gland. Average size of carcinoma was 3.6 cm. 5) Mean value of time interval between onset of symptom and diagnosis was 5.3 years. For benign pleomorphic adenoma it was 5.4 years and carcinoma was 4.7 years. 6) Chief complaint was painless, slowly growing mass which is not filed, firm, nontender in almost every cases of both benign and malignant tumors of the salivary gland.
