title: CT or US-guided fine needle aspiration biopsy in gastric neoplasms.
abstract: Gastric carcinoma of the linitis plastica type is occasionally difficult to diagnose endoscopically because of the large inflammatory response and the sparsity of tumor cells. Five patients who presented with signs and symptoms of gastric carcinoma underwent upper gastrointestinal endoscopy to confirm the diagnosis of carcinoma. In each case the gross appearance of the stomach was felt to represent gastric carcinoma but the biopsy and/or brushing specimens were unable to make the diagnosis. Ultrasound or CT in each of these five patients demonstrated thickening of the gastric wall and, in one instance, evidence of extensive metastatic disease. Fine needle aspiration biopsy was performed and a diagnosis of adenocarcinoma was made cytologically. Four were primary gastric adenocarcinoma of the linitis plastica type and one was metastatic adenocarcinoma from the breast. It is suggested that guided aspiration biopsy be performed when the diagnosis of gastric carcinoma cannot be confirmed endoscopically.
