Abstract
Neoplasms of the stomach are classified into two large categories on the basis of
the cell of origin: epithelial and nonepithelia. The vast majority of both benign
and malignant tumors of the stomach are of epithelial origin, with mesenchymal and
neuroendocrine tumors being much less common. The epithelial tumors arise from the
mucosa while the nonepithelial tumors arise from the submucosa, muscularis propria,
or serosa. The nonepithelial or intramural tumors of stomach include gastrointestinal
stromal tumors, leiomyomas, schwannoma, granular cell tumors, glomus tumor, leiomyosarcoma,
Kaposi sarcoma, lymphoma, and others. In this review, radiological appearance of mesenchymal
tumors and lymphoproliferative tumors are described.
