【Abstract】 In this paper two cases of rare ovarian sex cord tumor with annular tubules are reported, and their clinical and pathological features discussed. Histologically, the simple and complex annular tubules formation is the most characteristic feature of this tumor, by means of which it can be differentiated from other forms of ovarian tumor.After the primary tumor of the ovary has been removed, it tends to recur and metastasize. nevertheless this tumor belongs to a low malignant type, that is, it grows more slowly and its influence on the whole body is not very serious. If the tumor is diagnosed and treated early, the prognosis will be better.更多还原
