🙏A question from a subscriber. Hello, dear colleagues. Please help identify an object in the stool of a 50-year-old woman. Stool, native stain, 20× objective. I have highlighted the dimensions of the found object in the photo. I will post the 40× magnification in a comment below this post.

Equipment: KEYU F40
