What they are: Squamous cell carcinomas typically occur in warm, sunny climates (like ours!) and often show up on non-pigmented skin like white eyelids or sheaths. They are the most common malignant skin tumours in horses, and 18% of them will spread throughout the body. These lumps often appear innocuous at first and it is easy…
What they are: These are big, commonly dark-coloured masses that occur around the tail, genitals, mouth and throat-latch of mature grey horses. These tumours are usually benign and grow slowly, although in a small number of animals they will continue to be a problem and may even prove fatal. Owners typically notice a small nodule beneath…
What they are: Scars can form lumps and bumps anywhere on your horse's body. A scar forms when an injury heals but some disorganised tissue remains. Scars that occur across bones are especially noticeable. Scars typically feel somewhat hard, and perhaps stringy. In most cases, they are not sensitive to touch or pressure. Treatment: It is important that…

What they are: Abscesses are an accumulation of pus under the skin or in the deeper tissues. Abscesses can occur anywhere on a horse's body and are caused when a foreign body or infection stimulates white blood cells to congregate in one place. The white blood cells form pus and then the body starts to seal…
What they are: Nodules are referred to as simply nodules or as pressure bumps or sweat bumps. In medical terms they are referred to as eosinophilic granulomas with collagen degeneration, nodular collagenolytic granulomas or nodular necrobiosis. They are distinct, firm nodules about the size of a R2 coin, usually found on the neck, withers or back.…
What they are Seromas are fluid-filled sacs that occur secondary to direct trauma, such as being kicked by another horse. They usually start out as haematomas (bruises) that become seromas over the course of a few days or weeks. These lesions can appear anywhere on your horse's body but the most common locations are on his…

The difficulty comes in differentiating between the two variants. Over the next few days we will be running through several of the common causes of lumps and bumps, and what…
