OBJECTIVE
To test the validity of the reported high incidence (50%) of malignancy in neoplasms of the submandibular salivary gland, and to compare it with that of the parotid gland.
METHODS
This is a retrospective analysis of major salivary gland neoplasms in 127 patients who were treated between August 1988 and December 2004 (15 1/2 years) at Kalafong Hospital, Pretoria.
RESULTS
All but 1 of the patients were black. There were 100 benign and 27 malignant tumours. Thirty tumours were in the submandibular gland, including 3 malignant tumours, i.e. 10%. Of 97 parotid gland tumours, 24 (24.7%) were malignant.
CONCLUSION
The 10% incidence of malignancy in neoplasms of the submandibular gland in our series is much lower than the 50% reported in the literature. We postulate that race (black ethnicity) is probably a factor in this low incidence.
目的
检验所报道的下颌下唾液腺肿瘤中恶性肿瘤高发病率（50%）的真实性，并将其与腮腺肿瘤的发病率进行比较。
方法
这是一项对1988年8月至2004年12月（15年半）期间在比勒陀利亚卡拉方医院接受治疗的127例主要唾液腺肿瘤患者进行的回顾性分析。
结果
除1例患者外，所有患者均为黑人。有100例良性肿瘤和27例恶性肿瘤。30例肿瘤位于下颌下腺，其中3例为恶性肿瘤，即10%。在97例腮腺肿瘤中，24例（24.7%）为恶性。
结论
我们研究系列中下颌下腺肿瘤10%的恶性发病率远低于文献报道的50%。我们推测种族（黑人种族）可能是导致这一低发病率的一个因素。
