Two hundred and one cases of intraoral salivary gland tumors were studied from the files of the School of Pathology, University of the Witwaterstrand and South African Institute for Medical Research. 145 cases (72.5%) were classified as benign, comprising 140 pleomorphic adenomas and 5 monomorphic adenomas. The other 56 cases were classified as malignant or potentially malignant tumors, represented by 21 adenoid cystic carcinomas, 15 adenocarcinomas, 13 mucoepidermoid tumors, 5 carcinoma in pleomorphic adenomas and 2 epidermoid carcinomas. The patients in the malignant/potentially malignant group were significantly older than those in the benign group and a smaller proportion of their tumors were palatal, the difference being statistically significant. The high frequency of pleomorphic adenoma might result from a relatively higher number of black than white patients in this sample.
从威特沃特斯兰德大学病理学院和南非医学研究协会的档案中，对201例口腔唾液腺肿瘤进行了研究。145例（72.5%）被归类为良性，包括140例多形性腺瘤和5例单形性腺瘤。另外56例被归类为恶性或潜在恶性肿瘤，包括21例腺样囊性癌、15例腺癌、13例黏液表皮样肿瘤、5例多形性腺瘤中的癌和2例表皮样癌。恶性/潜在恶性组的患者明显比良性组的患者年龄大，且其肿瘤发生于腭部的比例较小，差异具有统计学意义。多形性腺瘤的高发病率可能是由于该样本中黑人患者的数量相对多于白人患者。
