A rare case of coexistence of ovarian cancer and gastrointestinal stromal tumor

Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors arising from the wall of the gastrointestinal tract with immunohistochemical reactivity for CD117 antibody, and usually prevalent in the fifth to seventh decade of life. The specific practical diagnostic criteria for GIST are c-kit expression (CD117), mitotic score, and the tumour size. The stomach is the most common site of localization. Surgery is the mainstay of the treatment and complete resection is achieved in most cases. Coexistence of malignant GIST and other malignancies from other germ layers have been reported in some unique cases. To the best of our knowledge the uncommon coexistence of GIST and ovarian cancer has not been reported in literature. We report the first case of a 63-year old female patient with two independent synchronous tumors, a GIST and an ovarian cancer.
