Two cases of retroperitoneal leiomyosarcoma are presented. The first case was in a 67-year-old female, whose chief complaint of right upper abdominal mass and dull pain. The tumor, 13 times 12 times 8 cm in size, developing in the retroperitoneum was removed with the right kidney and vena cava. The pathological diagnosis was reported as leiomyosarcoma. The second case was in a 62-year-old male, whose complaint was left abdominal swelling, also with general fatigue. A large tumor mass, invading over all of the left flank organs, was palpable by physical examinations, from which the mass was far beyond surgical approach. Needle biopsy revealed the pathological finding of leiomyosarcoma. One month later, the patient died of cachexia. Review of the literatures for the retroperitoneal leiomyosarcoma, revealed only a few cases; 1.7%, of all leiomyosarcoma to date.
