Cáncer gástrico: una presentación inusual / Stomach neoplasm: unusual presentation

We want to introduce the case of an 18 year old male patient who consulted us because of proctorrhage, straining and rectal tenesmus. Diagnosis was rectal tumor which pathological anatomy revealed an adenocarcinoma of cells in seal ring shape, suggesting a probable gastric origin. The high endoscopy evidenced multiple polyps, less than a centimeter wide found in the cardiac orifice, body and antrum, with the same histology. All these findings were confirmed during the exploratory laparotomy. We thought it was interesting to report this case because of the clinical presentation, unusual in this type of gastric cancer.
