15% of dogs with histiocytoma end with a tumor of bone tissue. Because histiocytomas have no identifiable cause, there is no way to prevent them from growing. They are not contagious, though, and cannot be spread through skin-to-skin contact. They do not pose any threat to any humans or any other animals that your dog may come into contact with.
Avoid bathing your dog or allowing vigorous activity until the incision heals, typically within 2 weeks. Remember not to give your dog any medication without the vet’s consultation. Canine histiocytoma has a few prominent characteristics for its diagnosis. Histiocytomas are usually small — less than 2.5 mm in diameter — and painless.
Histiocytoma Symptoms in Dogs
So long as the skin isn’t broken, inflamed, hot to the touch and/or weeping fluids then I personally wouldn’t be worried. If you do see any of those signs that would be cause for concern. The cells could be dying and drying out unevenly and that’s what’s causing the change in shape/appearance.
… It can form a big scab if it remains in a location with great deals of hair. There is no “root.” It’s just a clump of abnormal cells. It sounds like your vet in unnecessarily trying to scare you. Our elderly lab has a dime sized histocytoma that was growing rapidly, quite raised, looking like it was going to burst. We have an appointment to have it checked, but after reading this, I decided to try spraying it with vinegar twice daily.
Should a Histiocytoma be removed?
All that you’re describing is exactly what happened with my dog’s histiocytoma. The drying up and cracking is those abnormal cells drying up and dying. In my experience, most vets don’t like the idea of natural treatments because they just don’t know much about them, but still getting your vet’s input is important.
It is not uncommon for them to resolve on their own. Histiocytomas can occur in any breed of dog, but some breeds that they are more commonly seen in include boxers, bulldogs, and flat coated retrievers. Once your vet has definitively diagnosed your dog’s new lump as being a histiocytoma, they can then discuss with you removal options. Your vet may opt to wait and see what the growth does in the next few months. If after three months it is still there, your vet may recommend surgical removal.
Symptoms of Histiocytomas in Dogs
Because there is no cause of these tumors, there are no true preventative measures. Always do your best to keep your dog at its healthiest. Plenty of exercises, a proper diet, and annual trips to the veterinarian are some of the ways to keep your dog in its best shape.
Oral, laryngeal, and Conjunctival lesions may occur. The Dermatofibromas arise most frequently on the limbs and are usually asymptomatic but are pruritic occasionally. They are composed of histiocytes in varying proportions, young and mature collagen, fibroblasts, and capillaries, forming a nodule in the dermis that has poorly defined edges.
How to Treat Histiocytoma in Dogs
But what you may not realize is that you can use this healing oil topically too. It can help prevent cancer cells from multiplying and spreading. So it’s a great choice, whatever kind of skin cancer your dog has. You’ll want to add these important supplements to support your dog’s immune system. After all, your dog’s immune system is what will stop cancer cells from growing and spreading.
… Any growth believed to be a histiocytoma that is still present after 3 months should be removed. Any histiocytoma that is eroded or seems uncomfortable should be removed rather than waiting through the regression process. Though they’re considered ugly by most owners’ standards, these masses are benign. In fact, if left untreated they’ll spontaneously resolve within two to three months or less.

The majority of fix themselves in time without treatment, but surgical elimination is a choice if it is causing a problem for your dog. As with all growths, definitive diagnoses of the type of growth is done by looking at the cells microscopically. This is accomplished either by surgically removing the growth and biopsying it or performing something called a fine needle aspirate, or FNA. An FNA is performed by collecting cells from the growth on a needle and then transferring them to a slide to look at under the microscope.
Surgery usually requires full anesthesia, sutures, and an Elizabethan collar, and a recheck of the surgical site. If the histiocytoma is small enough, there is an option for cryosurgery, which uses liquid nitrogen to freeze abnormal cells and kill them, resulting in the tumor falling off. Canine Histiocytoma is a benign, pedunculated, or nodular neoplasm that arises from monocyte-macrophage cells in the skin. They are usually firm and well-circumscribed but sometimes, on palpation feel soft.
