The diagnostic challenge of metastatic linitis plastica. Two cases and a consideration of the problem.
Linitis plastica of the stomach is usually difficult to diagnose preoperatively and can extend locally and metastasize widely before recognition. This insidious manner of spread may cause unusual presentations in organs distant from the stomach. The authors recently treated two patients who were initially found to have radiologic abnormalities of the colon and bladder, respectively. One patient was surgically explored with a view towards the resection of a primary colonic tumor, the other to determine the nature of a bladder tumor. Intraoperative histologic interpretation of frozen tissue samples from the gastric wall in each case radically altered the surgical approach and the prognosis. The clinical presentations illustrate that it may be difficult to obtain preoperative diagnostic tissue samples in such cases and that it is important for the surgeon to inspect and palpate the stomach wall during all abdominal explorations for cancer.
