A rare case of pleomorphic adenoma in the external nose is reported. As a result of studies on the correlation between the sites of occurrence of pleomorphic adenomas reported and the sites of secretory glands with myoepithelial cells, it is found that pleomorphic adenomas occur in all secretory glands with myoepithelial cells. There are distinctive differences in the incidence in each part of the body, and in the hollow organs in the digestive and respiratory tracts: it is high in the face and decreases as the sites become farther away from the face. In the integumentary system, it is also high in the face. However, pleomorphic adenomas occurring in secretory glands without myoepithelial cells, and in non-glandular tissue such as the middle ear, paranasal sinuses, mesangial sinuses, vagina and tests can be considered either as those where glandular tissue and myoepithelial cells mingled during development (and thus are ectopic) or as those when invasion into adjacent organs occurred as the pathologic lesion (pleomorphic adenoma) expanded.
本文报道了1例罕见的外鼻多形性腺瘤。通过对已报道的多形性腺瘤发生部位与含肌上皮细胞的分泌腺部位之间相关性的研究，发现多形性腺瘤发生于所有含肌上皮细胞的分泌腺。身体各部位及消化和呼吸道中空器官的发病率存在显著差异：面部发病率高，且随着部位离面部距离的增加而降低。在皮肤系统中，面部发病率也高。然而，发生在不含肌上皮细胞的分泌腺以及中耳、鼻窦、系膜窦、阴道和睾丸等非腺组织中的多形性腺瘤，可被认为要么是在发育过程中腺组织和肌上皮细胞混合（因此是异位的），要么是在病理病变（多形性腺瘤）扩大时侵入相邻器官所致。
