Masses and skin growths near a mare’s vulva are common, especially in older mares. In gray mares of any breed, hard black nodules here are presumed to be melanoma until proven otherwise. In mares with pink vulvar skin (Paints and Appaloosas), squamous cell carcinoma is common. Occasionally, other tumors appear here, as do growths and skin inflammatory disorders caused by certain viruses.

WHAT TO DO

Check this area regularly when you are examining your mare. This is especially important for mares with pink skin here (pinto, Appaloosa horses) and especially in high altitude locales. Problems are relatively common in this area and unless you move the tail and look for them, you may never see them. Cancerous masses and growths of any kind are best treated early. Some cancers spread rapidly and can become hard to control.

Share your findings and concerns with your vet.

WHAT YOUR VET DOES

Your vet may have an opinion as to the nature of a specific condition, but masses here usually require biopsy for confirmation. Successful treatment will depend on an accurate diagnosis.
