Leiomyosarcoma of Colon

Leiomyosarcoma of Colon •The white rubbery cut surface is typical of a GIST tumor (Gastrointestinal Stromal Tumor) •The large size of this tumor suggests malignant potential, but is not as accurate as mitotic counts as an aid in classifying these tumors as benign or malignant •Necrosis and hemorrhage are found in malignant tumors, but in GIST tumors are related to the size of the tumor and are not an independant predictor of malgnanant potential (Description By:Martin Nadel, M.D. ) (Image Contrib. by: Hartford Hospital )
