Objective: This report was to review how extragastrointestinal stromal tumor (EGIST) was similar to ovarian cancer, its differential diagnosis and treatment.
Methods: Three cases of EGIST were reported and discussed by reviewing literatures.
Results: The cases of EGIST were presented with peritoneal and pelvic mass, or ascites, diagnosed as ovarian cancer at first, and finally diagnosed as EGIST by pathological method and positive CD(117) and CD(34) expression. Surgery in combination with chemotherapy was an effective therapeutic method.
Conclusions: Clinical presentation of EGIST is similar to ovarian cancer in some aspects. Detection of CD(117) and CD(34) positive expression is helpful in the diagnosis of EGIST.
