We report a case of a 75-year old male with a gastric submucosal mass, who underwent gastroscopic/laparoscopic wedge resection. Histopathology and subsequent immunohistochemical staining with CD117 (CKIT) and DOG1 revealed diagnosis of gastrointestinal stromal tumor, spindle cell variant. On genotyping, the tumor harbored PDGFRA D842V mutation, a subtype resistant to Imatinib treatment. </p>}, number={1}, journal={PJP}, author={Arceño, Jenissa Amor and Chua, Kathleen and Cabral, Loraine Kay and Dumasis, Arlie Jean Grace and Andal, Jose Jasper and Lo, Raymundo and Pua, Glenda Lyn and Ang, Daphne}, year={2018}, month={Feb.}, pages={16} }
