The Old Endoscopy Quiz (and Answer) of the Month - November 2015

Question:

This old gentleman came to an upper endoscopy as he suddenly had become quite anaemic. He had not experienced any gastrointestinal symptoms but felt a bit weak. These images shows the finding in the lower part of the gastric body. What is this?

Answer:

    An Ulcerated Gastric GIST


A gastric Gastrointestinal Stromal Tumour (GIST)

A GIST-tumour in the distal small bowel
Gastrointestinal Stromal Tumour (GIST), a sarcoma (a tumour arising from the connective tissue) of the gastrointestinal tract. GIST is rare, only about 1-3% of all malignant tumours in the gastrointestinal canal are of this kind. About two thirds of these tumours occur in the stomach, one fifth in the small intestine and one tenth in the oesophagus. GISTs are often benign, but larger tumours can cause liver and peritoneal metastases. Bleeding causing anaemia is the main symptom. Nausea, vomiting and weight loss are other common symptoms. Diagnose is most often made by endoscopy and biopsies taken during this examination. Surgical therapy is curative if the disease is not disseminated. These tumours have recently been found to respond very favourably to treatment with Imatinib (Glivec). Tumours formerly called leiomyomas and leiomyosarcomas are considered to be GISTs.
