This is the testicle of a 54 year old male with a cancerous germ cell tumor. I labeled the photo so you can see what is going on. The spermatic cord is where the testicle attaches to the inside of the body. When a patient has a testicle removed, that is where it is cut off the body. The testicle is almost completely taken over by this tumor. This is the testicle- it is cut in half. The middle of the tumor looks different because it is necrotic or dead. The outside of the spermatic cord is has been covered with green ink. We use ink in pathology so we can tell what we are looking at under the microscope. It is important to put ink on the outside of the testicle because if the tumor comes very close or invades the ink- this could change the stage of the cancer. The cord itself does not need to be inked, but sometimes it’s a mess and gets everywhere. Other times, people in pathology go by this theory: “don’t think, ink”. I personally disagree with anyone saying “don’t think“ in medicine. You get paid to think!
