A typical picture of GIST (Gastrointestinal Stromal Tumor) from a patient that went through a subtotal gastrectomy. GISTs are pretty common mesenchymal neoplasms of the GI tract. They are tumors of the connective tissue, which means that they are non-epithelial in origin, and are associated with several genetic mutations such as c-KIT mutations in more than 80% of the cases. The patient might have GI bleeding, trouble swallowing, intestinal obstruction and metastases to the adjacent organs (mainly to the liver). Surgical resection is the primary treatment of choice when a resectable GIST is present, although medications can be useful as well. Photo by @3odaay
