Megastomach caused by a pyloric schwannoma in a young woman

Schwannomas are mesenchymal tumors that are characteristically benign and slow growing, which originate from any nerve with schwann cell sheath. Here, we report the case of a 28-year-old woman patient who was diagnosed with stomach obstructive lesions causing severe gastric dilatation. She underwent distal gastrectomy and the histopathological examination of the tumor revealed one obstructive gastric schwannoma.
