自1964年O＇Brien等报告恶性纤维黄色瘤之后,国外报告日益增多,但命名繁纷混乱。1978年Weiss~1以恶性纤维组织细胞瘤(下称MFH)的命名报告200例,认为是中老年人最常见的软组织肉瘤,引起广泛注意。MFH在国内也不少见~(2-4)。此瘤可发生于身体各部位,临床缺乏特异表现,形态多变。了解MFH的病理特征,可避免与其他肉瘤混淆。临床资料 40例中男性25,女性15,二者之比为1.6:1。发病年龄4～80岁(中位43岁)。自发现至就诊的间隔时间1～96月(平均19.3月)。肿瘤的分布情况见附表。体表肿瘤多为无痛性结节状肿物,约1/5病人有疼痛。部分肿瘤近期突然增大。24例发生于软组织,
Since 1964, O’Brien et al. reported a malignant fibrosarcoma, foreign reports have been increasing, but the name is confusing. In 1978, Weiss~1 reported 200 cases of malignant fibrous histiocytoma (hereinafter referred to as MFH), which is considered to be the most common soft tissue sarcoma in the elderly, which has caused extensive attention. MFH is also not uncommon in China (2-4). This tumor can occur in various parts of the body, the clinical lack of specific performance, shape change. Understanding the pathological features of MFH can avoid confusion with other sarcomas. Clinical data 40 out of 25 males and 15 females had a ratio of 1.6:1. The age of onset was 4 to 80 years (median 43 years old). The interval from discovery to visit was from 1 to 96 months (average 19.3 months). The distribution of tumors is shown in the attached table. Most of the body surface tumors are painless nodular masses, and about one-fifth of patients have pain. Some tumors suddenly increased recently. 24 cases occurred in soft tissues,
