Abstract:Ovarian malignant tumor of non genital tract origin refers to the malignant tumor transferred to ovary by other organ systems other than genital tract, which is similar to primary ovarian cancer in clinical manifestations. It is difficult to differentiate the two and easy to be misdiagnosed and mistreated. Correct diagnosis and treatment is of great significance to improve the quality of life and survival rate of these patients. In this paper, the main points of identification of ovarian malignant tumor from non genital tract were discussed from the aspects of primary lesion, discovery time, metastasis route and clinicopathological manifestations, and the selection of operation time and operation scope was reviewed based on the disease condition, so as to provide reference for clinical diagnosis and treatment.
