A 57-year-old woman was admitted because of vomits and weight loss. Gastroscopy revealed thickened gastric folds and poor distension on insufflation. CT-scan and EUS showed no additional abnormalities. Two repeat sets of biopsies, sampling by unroofing technique and EUS-FNA were inconclusive.

The patient was proposed for deep submucosal biopsies assisted by ESD tunneling technique aiming a histological diagnosis to guide treatment. A mucosal incision was made in the proximal body. Submucosal dissection was continued until an extremely fibrotic area was reached. Biopsies taken with a standard biopsy forceps showed poorly differentiated carcinoma. The patient underwent total gastrectomy confirming this diagnosis.
