Rufus has a red pimple like bump on his lower eyelid near the tear duct that is 3 millimeters in size (sorry about the metric measurement). It first appeared a week ago as a raised area that was the same color as his eye lid that later became dry and slightly scaly (like a when your skin is really dry and it flakes off) and now red. About a year ago he had a similar bump on his muzzle where his whiskers grow that looked exactly the same. We figured it was an inflamed hair follicle and it disappeared on its own in a weeks time so we did not give it a second thought. This time the bump is so close to his tear duct and it has not decreased in size so we took him to the vet today to get it checked out.

Our vet is not sure what it is, he thinks it could be one of two things, either Hystiocytoma or a Mast Cell Tumor. He is optimistic that it is Hystiocytoma since the previous bump resolved itself. Hystiocytoma is common in younger dogs (Ruf is 2yrs old) and usual goes away on its own. We are supposed to keep a close eye on it and if it goes away on its own we are in the clear. Because of the location of the bump if it begins to grow we have to get it removed ASAP before it becomes too big to remove it only without compromising the eye. Also if it does not go away it needs to be removed as well because it probably is not Hystiocytoma. I looked both up on the net and I pary that it goes away on its own.
