TUESDAY TRIVIA ANSWER

This is an example of a cancer called squamous cell carcinoma [SCC].  We will see this in white areas (areas where there is no pigment) around the eyes, nose, and on the penis of male horses.  Prevention is key in horses with predisposing white areas; there are even special fly masks available that block UV rays (a predisposing cause of SCC).  Having questionable areas checked out by your veterinarian is also a good idea as most SCC growths are easier to treat when they are diagnosed early.
