Abstract
Molecular genotyping of gastrointestinal stromal tumors is not yet available in the Philippines. 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.
