支气管类癌(bronchial carcinoid)是起源于支气管上皮组织嗜银细胞的恶性肿瘤,变称肺类癌。近年经电镜和组织免疫化学研究认为类癌和未分化小细胞癌均来自支气管上皮的嗜银细胞(kultshitsky cell),故又有人称支气管嗜银细胞瘤(bronchial argentaffinoma),这些细胞浆内含有神经内分泌功能。属少见病,术前易误诊、漏诊,部分病例可诱发类癌综合征,该肿瘤应进一步引起广大医务工作者重视,本文仅将近年来有关支气管类癌的情况简要综述如下。
Bronchial carcinoid (bronchial carcinoid) is a malignant tumor originating from argyrophilic cells in bronchial epithelial tissue, which is called lung carcinoid. In recent years, by electron microscopy and immunohistochemical studies that carcinoid and undifferentiated small cell carcinoma are derived from the bronchial epithelial cells (kultshitsky cell), it is also called bronchial argentaffinoma (bronchial argentaffinoma), the cytoplasm contains nerve Endocrine function. Is a rare disease, preoperative misdiagnosis, missed diagnosis, in some cases can induce carcinoid syndrome, the tumor should further pay attention to the majority of medical workers, this article only in recent years, the case of bronchial carcinoid briefly summarized below.
