AU - Thoriya,Prashant J. AU - Bahri,Nandini U. AB - Neoplasms with histology and immunohistochemistry similar to gastrointestinal stromal tumors may occur primarily outside the gastrointestinal tract, usually in the omentum and mesentery. These are referred to as extragastrointestinal stromal tumors (EGISTs). Retroperitoneum is a very rare site for such neoplasms. We report a patient with EGIST in the retroperitoneum, elaborating the cross-sectional imaging and histopathologic findings. VL - 4 SP - 34 SN - 2156-7514 SN - 2156-5597 ER -
