Gastric cancer with soft tissue metastasis of the abdominal wall: a case report

Abstract

Abstract Abdominal wall metastasis of gastric cancer (GC) is a very rare occurrence in the clinic setting. We recently diagnosed and treated a patient with abdominal wall metastasis of GC and we hope to provide some helpful guidance on the clinical diagnosis and treatment of this disease.A 49-year-old male patient with GC was admitted to our hospital (Dalian Municipal Central Hospital, Dalian, China) complaining of left upper abdominal wall mass. Physical examination and regular laboratory blood tests showed no obvious abnormalities. Ultrasound and CT of the abdomen showed a subcutaneous solid mass in the abdominal wall. Radical gastrectomy was performed on February 27, 2019, six months after it was first noticed by the patient. Pathological examination and immunohistochemistry showed GC with abdominal metastasis. Postoperative radiotherapy or chemotherapy was not pursued after the second operation and no recurrence or metastasis has been noted so far. GC with abdominal metastasis is very rare and can be easily missed or misdiagnosed. For metastasis to a single site in the abdominal wall, surgical resection, which is recommended, may improve patient outcomes.
