四肢横纹肌肉瘤临床少见,X 线片表现不一,组织形态多样,故较易误诊。我院自1974年以来,共收治8例,现报告如下。床资料本组8例临床资料见附表。讨论四肢横纹肌肉瘤系常被误诊的恶性肿瘤之一,文献报道其误诊率高达56.25～91.3%。本组8例术前均未确诊,现结合文献复习,谈点粗浅体会。一、凡四肢长骨中段部位无痛性、质(稍)硬,边界较清楚,仅能左右移动及生长缓慢的梭形肿块,应想到为本瘤之可能。应尽早活检,以明确诊断。若肿块穿刺抽出物含有暗褐色血性液体,则本瘤之可能性更大,应进一步活检证实。 Rhabdomyosarcoma of the limbs is rarely seen clinically. The X-ray films have different manifestations and are organized in various forms. Therefore, it is more likely to be misdiagnosed. In our hospital since 1974, a total of 8 cases have been treated. The report is as follows. Bed data The 8 cases of clinical data in this group are shown in the attached table. Discusses one of the malignant tumors that are often misdiagnosed as limb rhabdomyosarcoma. The misdiagnosis rate reported in the literature is as high as 56.25-91.3%. This group of 8 cases were not diagnosed before surgery, now combined with literature review, talk about the superficial experience. 1. Wherever the mid-length parts of long limbs are painless, qualitative (slightly) hard, and the boundaries are clear, only spindles that can move left and right and grow slowly can be thought of as possible tumors. Biopsy should be performed as soon as possible to confirm the diagnosis. If the puncture aspirate contains dark brown bloody fluid, the tumor is more likely to be confirmed by biopsy.
