涎腺上皮性肿瘤中,良性多形性腺瘤最多见,约占53％以上。正如多数良性肿瘤都具有相应的恶性肿瘤一样,良性多形性腺瘤的相应恶性肿瘤为恶性多形性腺瘤或恶性混合瘤。由于恶性多形性腺瘤少见,组织类型复杂和分类方法不一,因而造成诊断名称上的混乱,直接影响了对该肿瘤发生率的统计和临床上的防治。为此,现将我院口腔病理室收集的35例恶性多形性腺瘤的临床病理资料进行了分析,初步提出诊断标准和组织病理分型意见,以资讨论。
Among benign epithelial tumors, benign pleomorphic adenomas are the most common, accounting for more than 53%. Just as most benign tumors have corresponding malignant tumors, the corresponding malignant tumors of benign pleomorphic adenomas are malignant pleomorphic adenomas or malignant mixed tumors. Because the malignant pleomorphic adenomas are rare, the types of tissues are complex and the classification methods are different. As a result, confusion in the names of the diagnoses has a direct impact on the statistical and clinical prevention and treatment of the incidence of the tumor. To this end, the clinical pathological data of 35 cases of malignant pleomorphic adenomas collected in the Oral Pathology Department of our hospital were analyzed, and the diagnostic criteria and histopathological classification were initially proposed for discussion.
