I'm going to start a series of guess what's in the slide? It's exactly what it says.
Specimen: Ovary. Identify the structure seen here.
The Answer: Corpus albicans
It's the degenerate form after the corpus luteum has fulfilled its role. It got its name albicans (white) due to how lighter it is during grossing the specimen. The hyaline (pink)colors are just the stains.
The Winner: @demotry
Notes: I didn't expect the amount of participants within the first 24 hours given how small this community is. @smokrthou came second by a few minute different. Take my vote as consolation, and all the rest that gave it a shot.
I'll be starting with 1 HBD. The first one that guesses this right gets that HBD. The prize gradually increases when no one gets it right for each successive post on the series. At the very least, each post has a 1 HBD bounty on it. I'll prioritize adding more bounties on older questions compared to new questions in the series.
The mechanics of the guessing game:
I post the images and give a small detail about it with a corresponding question.
Comment the answer and whoever gets it right first wins the prize. There's a time stamp on the comment section so it's easy to determine the winner if multiple users got it right.
In the event that no one gets it right, the contest will still be open indefinitely. Feel free to ping me if you backread the previous posts in the series.
I'll add new conditions to the game as needed.
You are free to Google for answers or use whatever means you got at your disposal with a corresponding reason why you think it is so. It's easy to get it right by throwing words around so I want to see whether you studied the image.
Make as many attempts as you want. The only time an attempt isn't allowed is when the contest has been closed. There can only be one winner per post. You can multiple times.
Note:
I'll be copypasting the mechanics of the game including this line so that anyone who is new to the series wouldn't have to click more links just to backtrack what's going on. If anyone wants to cry I'm milking the reward pool by posting copy paste posts, understand the images here are from actual cases where I took the time to have them recorded.
I highly encourage you to research the answer in the hopes you can actually learn from the experience. Pathology is fun.
I'm also confident you can't find any image that match exactly as the ones I'm sharing because these are from my personal study slides. You can of course see similar images because they can show the same histomorphologic findings you'd expect from the specimen.
Good Luck!
If you made it this far reading, thank you for your time.
