Gastrointestinal Stromal Tumor - History

History

Until the 1990s, all nonepithelial tumors of the gastrointestinal tract were called "gastrointestinal stromal tumors" from smooth muscle origin.

Subsequently, CD34, and later CD117 were identified as markers that could distinguish the various types.
