This women had TAH-BSO for leiomyoma and her right ovary shows the above incidental findings, what's your diagnosis? What else should we do?

 Thank you for all the discussion. Dr. Zhao's comment is very good. This is the third case of SCTAT I have seen and the first two, both had gross mass lesions. This one only has microscopic foci. I showed the case to several of my fellow pathologists who are good at GYN path, someone suggested to call this "SCTAT tumorlet", and others suggested "microscopic SCTAT). I decided to go with the later terminology basically because I was worried that some clinicians would not understand what is exactly SCTAT tumorlet.

 I think abin's post is very good, I did call the gynecologist to discuss the possibility of PSJ, she checked her up completely and there is no evidence of PJS. In the mean time, I asked my resident to submit the whole cervix to make sure that there is no adenoma malignum, and that came back negative. So, I guess that this case was exciting at the beginning and it just turns out to be an incidental finding.

 Most of people get the diagnosis of Sex Cord tumor with Annular tubules (SCTAT). The questions I am asking are:

 1) How big has the tumor to be qualified as SCTAT? remember this is an incidental finding and the focus is <5 mm.

 2) What syndrome is SCTAT associated with (about 33%)? and what you need to inform the clinician to check on this patient?
