EQUINE CUTANEOUS LYMPHOMA - A CASE-REPORT

The history, clinical and histological features and response to treatm ent of a 15-year-old horse with cutaneous lymphoma are described. The mare had an 11 year history of multiple cutaneous nodules. A diagnosis of cutaneous lymphoma was made on histological examination of biopsy material taken on two separate occasions some 4 years apart. Subsequen t immunohistochemical staining identified the cell lineage as T-lympho cytes. This is the first report of immunophenotypic characterisation o f cutaneous lymphoma in the horse. The horse was treated with intrales ional glucocorticoids and oral progestins, and complete resolution of the nodules resulted.
