上皮-肌上皮癌(epithelial-myoepithelial carcinoma,EMC)是一种低度恶性的涎腺肿瘤,好发于中老年女性,80%发生在腮腺,小涎腺少见[1]。发生于支气管的上皮-肌上皮癌是支气管恶性肿瘤中罕见的类型,组织学特征类似于涎腺的上皮-肌上皮癌。肿瘤由伴有梭形细胞、透明细胞或形态类似浆细胞样的肌上皮细胞和不等量的导管上皮组成。
Epithelial-myoepithelial carcinoma (EMC) is a low-grade salivary gland tumor that occurs in middle-aged and elderly women, with 80% occurring in the parotid gland and rare in the salivary glands [1]. Bronchial epithelial-myoepithelial carcinomas are a rare type of bronchial malignancy with histological features similar to epithelial-myoepithelial carcinomas of the salivary gland. The tumor consists of myeloid cells with myeloid cells, clear cells or plasmacytoid cells in similar morphology and an unequal amount of ductal epithelium.
