Gastrointestinal stromal tumor(GIST) is the most common mesenchymal tumor of the gastrointestinal tract. Because The tumor is usually located in the stomach and proximal small intestine, If GIST is detected in pelvic cavity, it is easy to misdiagnose as gynecological mass such as ovarian cancer, uterine myoma, uterine sarcoma, etc. This case is here. A 78-year-old woman presented with abdominal discomfort with pelvic mass. We performed blood test including CA 125, CA 19-9 and pelvic ECT. Pelvic ECT revealed heterogenous density mass, measuring 9cm and possibility of uterine exophytic myoma or Lt. ovarian cancer was suggested. And then, we performed exploratory laparotomy operation. But the mass was found in jejunum and was finally diagnosed as GIST throughout histopathological examination. Although GIST is low incidence tumor and does not have specific appearance on radiological examination, Gynecologists need to be alert of extra gynecological pathology in patients presenting with an unusual pelvic mass.
