What is a Squamous Cell Carcinoma?
It is a tumour of cells called squamous cells. Squamous cells are found lining the surface of the skin and the inside of the mouth (plus other areas).
Squamous Cell Tumours can be triggered by sun exposure.
Common areas we see them in horses are the eyelid margins or third eyelid, and on pink skin over the face.
Sun damage to the eyelids or third eyelid is seen as mucosal irritation or irregularity. We can treat the damaged tissue at this stage before it progresses into tumour cells.
Once a tumour has developed, we need to treat it with one of the following:
Surgical resection
Cryotherapy
Chemotherapy

The third eyelid tumour was treated with removal of the eyelid.
The tumour on the lower chin has had multiple rounds of cryotherapy and chemotherapy.
TOP TIP:
Look at all pink skin on the face and eyes regularly.
