摘要
唾液腺非侵袭性恶性多形性腺瘤(Ca-ex-PA)又称发生在多形性腺瘤中的原位癌,是较少见的病理类型,临床表现与良性多形性腺瘤相似,有条件完整切除肿瘤,复发或转移少见,预后良好。本文报告1例下颌下腺非侵袭性多形性腺瘤的临床病理学特征,认为鉴别非侵袭性Ca-ex-PA和侵袭性Ca-ex-PA对判断预后十分重要,并影响治疗方案的选择,WHO对唾液腺多形性腺瘤恶变的分型在肿瘤的生物学行为和预后方面具有实际意义。
A case suffering from non-invasive malignant pleomorphic adenoma of the submandibular gland was reported. The clinicopathologic characteristics of non-invasive malignant pleomorphic adenoma of the salivary gland were analyzed. Non-invasive malignant pleomorphic adenoma was rare in the salivary gland . Misdiagnosis of the tumors usually occurred clinically and pathologically. WHO histological typing is important in evaluating biological behavior and prognosis of malignant pleomorphic adenoma of the salivary glands.
