目的 :为加深对皮肤粘膜罕见良性肿瘤的认识。方法 :结合有关文献分析了近年来作者所遇多形性脂肪瘤、疣状黄瘤和皮样瘤等三种皮肤粘膜罕见良性肿瘤的临床病理资料。结果 :它们各具临床病理特点 ,但多形性脂肪瘤易误诊为多形性脂肪肉瘤 ,疣状黄瘤易误诊为黄色肉芽肿。结论 :皮肤粘膜肿瘤虽然依据病理学检查较易诊断 ,但常误诊 。

Objective To get deeper understanding of benign tumors rarely seen at the skin and mucosa.Method This article analyzed the clinicopathological data of three benign tumours,pleomorphic lipoma,verruciform xanthoma and dermoid tumor,rarely seen at the skin and mucosa,and reviewed relational documents.Results They had their clinicopathological features,respectively,but the pleomorphic lipoma commonly was misdiagnosed as pleomorphic liposarcoma and the verruciform xanthoma was misdiagnosed as xanthogranuloma.Conclusion Although their diagnoses easily obtained according to their pathological examinations,misdiagnoses were commonly seen,therefor we must pay attention to their distinguishing diagnosis.
