Synchronous occurrence of colon adenocarcinoma and gastric schwannoma. Case report and review of the literature
Main Article Content
Abstract
MATERIAL OF STUDY: We report a case of a 66-year-old man with a gastric schwannoma incidentally discovered during the treatment of a colon cancer. At the pre-operative computed tomography performed for the stadiation of the colonic tumor was incidentally noted the presence of a nodular tumor between the liver and the gastric wall.
RESULT: A wedge resection of this gastic tumor and the surgical resection of the left colon were performed all at once. The pathological examination of the gastric neoplasia revealed a picture consistent with gastric schwannoma.
DISCUSSION: Gastrointestinal schwannomas are difficult but not impossible to diagnose preoperatively although they are often asymptomatic and radiologic findings are often nonspecific. Radiological features of Gastrointestinal schwannomas described in literature are reviewed.
CONCLUSIONS: The treatment of choice is complete surgical excision with free margins because of diagnostic uncertainty, and the long-term outcome is excellent as these lesions are uniformly benign.
