Gastric lymphoma vs adenocarcinoma. A diagnostic problem.
The prevalence of gastric lymphoma is increasing relative to gastric carcinoma. The differentiation between these two diagnoses can be difficult, but it is important from the standpoint of treatment and prognosis. These case reports illustrate that the results of gastroscopy, biopsy, and cytology may be misleading. If there is any question at the time of exploration, a biopsy and frozen section should be obtained before proceeding further or before closing the abdomen without resection. The pathologic diagnosis will determine the operation and postoperative treatment to be carried out.
