A case of solitary metastasis of gastric cancer to skeletal muscle

Abstract

A 61-year-old woman was admitted to our hospital for treatment of a left lower abdominal wall tumor. She had undergone total gastrectomy for stage IB gastric cancer 11 years earlier. Abdominal CT scan and ultrasonography showed a mass more than 30mm in size in the left abdominal wall. On aspiration cytology, metastasis to the abdominal wall from gastric cancer was suspected. Since no other metastatic site was revealed, she underwent tumorectomy. Pathologically, the resected specimen was a poorly differentiated adenocarcinoma similar to her primary gastric cancer, suggesting that this tumor was a metastatic lesion from the gastric cancer. Solitary metastasis of gastric cancer to skeletal muscle is rare, especially the presentation of a relapse after more than 10 years. Therefore, we describe this case together with a review of the literature.
