An unusual case of colonic leiomyosarcoma presenting with fever--significant uptake of radioactivity of gallium-67 in the tumor.
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.
