Definition of Equine Lymphoma in Horses
Lymphoma is one of the most common cancers of the horse. It is a cancer originating from a white cell called a lymphocyte that is found in lymphoid tissue. Equine lymphoma is classified into the following clinical syndromes: multicentric or generalized, alimentary, mediastinal, cutaneous, and solitary tumours of extranodal sites.

Treatment of Equine Lymphoma in Horses
Treatment options are limited and often cost-prohibitive, and advanced disease progression at the time of diagnosis means that euthanasia is usually opted for, as treatment is very rarely curative. The form of lymphoma will dictate the options available for treatment. Treatment is only palliative (prolonging life) rather than curing the disease. However, in solitary and some cutaneous lymphomas where surgical removal is possible a cure may be achievable, assuming there is no other disease elsewhere. If end-stage/advanced lymphoma is present then there are limited options available.
Surgical excision of solitary tumours: The unusual form of lymphoma that occurs in the conjunctiva of the eye region is best treated with surgery.
Chemotherapy: Lymphoma can be treated with multi-drug protocols or with corticosteroids alone. Hormonal therapy: Some lymphomas are responsive to progesterone therapy (especially cutaneous forms of lymphoma).
Prevention of Equine Lymphoma in Horses
There is no way of preventing the development of Equine Lymphoma. An earlier diagnosis may improve prognosis if therapeutic options are viable to owners, so lymphoma should be considered as a differential diagnosis in many cases.
