Giant gastrointestinal stromal tumor of the stomach in an elderly patient.
We report a case of giant gastrointestinal stromal tumor (GIST) of the stomach of 17 cm in diameter detected in an 88-year-old Caucasian female. An en-block resection of the mass requiring gastric and transverse colon resection was carried out. Pathological examination evidenced a smooth multicystic giant gastric GIST measuring 17 x 13 x 9 and weighing 1,630 g. At immunohistochemistry, the specimen was c-kit positive, CD34-positive, SMA-negative S100-negative, desmin-negative, CD31-negative, HMB45-negative, and calponin-negative. It was diagnosed as an uncommitted GIST at high risk for malignancy.
