Laparoscopic treatment of a series of rare tumors, gastric schwannoma with chronic iron deficiency anemia: A case report

INTRODUCTION AND IMPORTANCE: Gastric schwannoma is a rare and slow-growing gastrointestinal mesenchymal tumor. Gastric neurilemmoma accounts for less than 1% of all gastric tumors. Without specific clinical manifestations, it is easy to be misdiagnosed before the operation, and rupture and bleeding will lead to persistent anemia in patients. The diagnosis can only be confirmed by pathological examination. CASE PRESENTATION: A 55-year-old woman was admitted to The Second Hospital of Lanzhou University due to abdominal distension, pain, acid regurgitation, and belching. The tumor was completely removed by laparoscopy. The postoperative specimens were diagnosed as gastric neurilemmoma by pathological examination. CLINICAL DISCUSSION: Schwannoma is a benign neurogenic tumor. Complete surgical resection with a negative cutting edge is an effective method for the treatment of gastric schwannoma. Because the lesion is benign, the prognosis of the patient is good. CONCLUSION: Laparoscopic tumor resection is a choice for the treatment of gastric schwannoma, and the therapeutic effect is good.
