Soft tissue sarcomas (STS) are very rare tumors, accounting for <1% of all malignancies. Leiomyosarcoma (LMS), accounts for 10-20% of STS. Gastric metastasis of LMS is extremely rare, and only a few cases have been reported. In the present report, two clinical cases of LMS with gastric metastasis. In the present cases, the metastases presented as a solitary lesion and was located in the upper body anterior wall in case 1, and body-greater curvature in case 2. It is debatable whether to perform any local treatment for gastric metastasis due to its poor prognosis. However, the progression of metastatic cancer in the stomach can lead to gastric bleeding, abdominal pain, and dysphagia, which may further shorten survival and decrease a patient's quality of life. Therefore, metastasectomy was performed in the present cases. This should be considered if digestive tract symptoms occur during the treatment of LMS.
Keywords: gastric metastasis; leiomyosarcoma; metastasectomy; prognosis; soft tissue sarcoma.
