Pathology Puzzles Project gives an opportunity to all the specialists to study interesting morphological cases. It is not only a good educational opportunity but also a chance to discuss the cases within the pathologists’ community. Every month three cases will be uploaded into the Digital Pathology system. Before uploading the cases minimum two specialists will validate them.

  1. Left ovary, fallopian tube, excision: Serous tumor of low malignant potential (LMP)/Atypically proliferating serous tumor. Hydrosalpinx. Focal endometriotic implant.

All submitted slides were reviewed in conjunction with recut slides (x3) prepared from blocks B4 B9, B10 B11. More
