喉非上皮性良性肿瘤发病率较低,约占喉肿瘤的2％,其中恶性为0.32～0.5％。作者于1961～1980年观察治疗12例,其中软骨瘤1例,血管瘤6例,神经纤维瘤2例,纤维瘤3例。喉软骨瘤:多发生于中年女性,随年龄增长有恶变倾向。恶变时组织学特点:①细胞和细胞核大小明显不规则,②有许多多核细胞,③核染色质增多,④具有任何一种单核或多核,其染色质凝成粗块状巨形软骨细胞。本病诊断仍依据组织病理学,治疗以手术切除为 Malignant throat non-epithelial benign tumor incidence is low, accounting for about 2% of laryngeal tumors, of which malignant 0.32 ~ 0.5%. The authors observed and treated 12 cases from 1961 to 1980, including 1 chondroma, 6 hemangioma, 2 neurofibroma and 3 fibroma. Laryngeal chondroma: Occurred in middle-aged women, with malignant tendency of aging. Malignant histological features: ① cell and nucleus size was significantly irregular, ② There are many multinucleated cells, ③ increased nuclear chromatin, ④ have any kind of single or multiple nuclei, the chromatin coagulation into massive chondrocytes. The diagnosis of the disease is still based on histopathology, the treatment of surgical resection
