Invasive Cancer of the Colon with Gastric Metastasis

The stomach is a very rare location of metastatic deposits. We present a case of a gastric metastatic deposit from primary colon cancer. Computed tomography (CT) indicated primary colon cancer, but also revealed the presence of cancer in the region of the gastric greater curvature and gastric antrum. With the progression of primary cancer and the creation of an extraluminal tumor mass, the process progresses in the manner that the primary transversal colon tumor merges into the metastatic deposit located in the stomach. The patient underwent subtotal gastrectomy and D2 lymphadenectomy, as well as partial resection of the transversal colon, thus the tumor mass of the stomach and the one in the transversal colon being removed in a single act. Pathohistological analysis of the tumor mass and immunohistochemical tests revealed a primary neoplastic infiltrative process in the colon metastasizing into the stomach.
