Spleen

🩺 Before you name anything

Take a deep breath and let's start at low power. Look for the overall architecture: do you see a mix of darker and lighter areas? That's your first clue. The spleen is unique because of its white pulp and red pulp. The white pulp appears as circular or oval nodules, often with a central arteriole, contrasting with the surrounding red pulp. Students often rush to high power and get lost in the cellular details, missing the bigger picture. Focus on identifying these nodules first. Once you see them, you'll know you're looking at the spleen. Remember, it's the contrast between the white and red pulp that confirms it. In this field, the distinction may not be clear, so refer to a better slide if needed.
