Leiomyosarcoma of the large intestine, excluding the rectum, is a rare lesion and only 58 cases have been previously reported. Significant uptake of radioactivity of gallium-67 to the tumor has not been reported and this report may be the first case. Although preoperative diagnosis is considered to be difficult, barium enema study and colonofiberscopy disclosed the findings suggesting extracolic growth of the tumor in our case, which are thought to be characteristics of nonepithelial tumors. Gallium-67 citrate scanning may be useful for confirming the diagnosis.
大肠平滑肌肉瘤（不包括直肠）是一种罕见的病变，此前仅有58例报道。此前尚未有关于肿瘤对镓-67放射性摄取显著的报道，本报告可能是首例。尽管术前诊断被认为困难，但在我们的病例中，钡剂灌肠检查和结肠镜检查发现提示肿瘤有结肠外生长，这被认为是非上皮性肿瘤的特征。枸橼酸镓扫描可能有助于确诊。
