[Ovarian sex cord tumor with annular tubules--report of 2 cases].
Ovarian sex cord tumor with annular tubules is exceedingly rare. Only 8 cases have been reported in the Chinese medical literature and the author adds two more cases. Patient 1, a 30-year-old woman, with her tumor discovered during health check-up, had subsequent profuse menses. Patient 2, a 19-year-old girl, presented with irregular uterine bleeding since menophania. The tumors in both cases were medium-sized in the right ovary, with typical histological pattern and benign characteristics. The first patient is living and well 2.5 years postoperatively and the second patient has fully rehabilitated 4 months after resection. The latter case, having hyperplastic endometrium with diffuse polypoid protrusion extruding through os cervix, was misdiagnosed as "botryoides sarcoma". To our knowledge, such presentation has not been reported previously.
