Mesenchymal Neoplasms of the Gastrointestinal Tract and Liver—It’s All About Location

This lecture offers the following credit types: CME, P.A.C.E.®, Florida
 

This presentation covers several mesenchymal lesions with a focus on the anatomic site and the layer within the gastrointestinal tract (mucosa, submucosa, muscularis propria, serosa) that specific lesions are likely to arise. Mucosal nerve sheath tumors are addressed in some details as well as inflammatory myofibroblastic tumor, inflammatory fibroid polyp, fibromatosis, and a few comments on gastrointestinal stromal tumors.
