  Schwannomas, also called neurilemomas, are neurogenic tumors derived from Schwann cells of nerve sheath. They are relatively common in head, neck, extremities, retroperitoneum, posterior spinal roots and cerebellopontine angle, and are generally benign and slow-growing with rare recurrence or malignant transformation. However, they are rare in the gastrointestinal (GI) tract and mostly located in the stomach. Gastric schwannomas represent about 2% of the gastric mesenchymal neoplasms, and are clinically and grossly nearly indistinguishable from gastrointestinal stromal tumors (GISTs). GISTs are the major primary mesenchymal tumors of the GI tract. They have a variable malignant potential and can be coexistent with renal cell carcinomas (RCCs). In contrast, gastric schwannomas are regarded as benign and no concurrent malignancies have been documented. Here, we report a 54-year-old woma.. Read More»
