Gastric Pyloric Schwannoma: A Case Report and Review of the Literature
IntroductionSchwannomas are slow-growing, subclinical neoplasms rarely found in the gastrointestinal tract. This study reports a schwannoma in the pyloric region of the stomach.
Case presentationA 50-year-old female presented with a one-week history of epigastric pain, dark tarry stools, and nausea. Endoscopic examination and biopsy confirmed the diagnosis of gastric schwannoma. The patient underwent surgical resection of the tumor. Histopathological examination showed benign spindle cells with strong S100 positivity, confirming schwannoma. Post-operative follow-up included treatment for H. pylori infection and monitoring for recurrence or complications. No recurrence was reported after six months.
Literature ReviewGastric schwannoma is challenging to distinguish from other submucosal tumors preoperatively. Reviews of recent case reports indicate the importance of detailed imaging in diagnosis, and surgical resection remains the treatment of choice, with an excellent prognosis and low recurrence rates.
ConclusionSchwannoma is rare in the stomach, especially in the pyloric region. Definitive diagnosis may require immunohistochemical analysis. Appropriate follow-up after treatment can be essential to identify emerging complications and ensure timely intervention.
