多形性腺瘤(pleomorphic adenoma,PA)是一种好发于涎腺的良性肿瘤,但具有很高的复发率和恶变率。乳腺PA在2012年WHO乳腺肿瘤分类中的定义为一种少见的、形态学类似涎腺PA(良性混合瘤)的病变~([1])。所谓多形性是指组织结构多形性而不是肿瘤细胞多形性,可有上皮、肌上皮、间叶或间质成分,上皮细胞可呈立方、基底样、鳞状、片巢状、条索状排列或呈管样结构~([2])。南昌大学第一附属医院收治乳
Pleomorphic adenoma (PA) is a benign tumor that is salivary gland, but has a high recurrence rate and malignant transformation rate. Breast PA is defined in the WHO classification of breast cancer in 2012 as a rare, morphologically similar lesion of salivary gland PA (benign mixed tumor) ~ ([1]). The so-called pleomorphic refers to the pleomorphic tissue structure rather than tumor cell pleomorphism, may have epithelial, myoepithelial, mesenchyme or interstitial components, epithelial cells can be cubic, basal-like, squamous, nested, Cable arrangement or tube-like structure ~ ([2]).
