Gastric stromal tumors give diagnostic and therapeutic problems, especially with regard to histopathologic identification and biological behavior. These tumors are very rare in all case reports. These ones are the most frequent of all alimentary tract. They are often incidentally found; because of their potential transformation, they have to be treated by respecting oncologic eradication standards and observing prognostic criteria based on a correct histopathologic evaluation (neoplasm localization and dimension, its structure, presence of cytological atypisms, mitotic index, ploidia, surgical resection). Then there has to be a good follow-up program.
