Leiomyosarcoma of an artery is very rare, and cases with hepatic metastasis are even rarer. We describe a case of a 70-year-old man who after follow up due to rectal cancer, presented with an intra-abdominal hypervascular mass and a hepatic mass. After surgical resection, it was diagnosed as a leiomyosarcoma of the right gastroepiploic artery with hepatic metastasis. Multiple metastases had recurred at the liver. He has survived more than 53 mo through multimodal treatments (three surgical resections, radiofrequency ablation, transarterial chemoembolization, chemotherapies, and targeted therapy). Multimodal treatments, including active surgical resection, may be helpful in the treatment of aggressive diseases such as arterial leiomyosarcoma with metastasis.
Core tip: An arterial leiomyosarcoma (aLMS) is a very rare and aggressive disease. The prognosis is also very poor. A 70-year-old man presented with an intra-abdominal aLMS with hepatic metastasis. He was treated with multimodal treatments that consisted of three surgeries, radiofrequency ablation, transarterial chemoembolization, and targeted therapy. He has survived for 53 mo after these treatments. Multimodal treatments could be helpful treating this kind of disease.
