Kl. Henson et al., REGRESSION OF SUBCUTANEOUS LYMPHOMA FOLLOWING REMOVAL OF AN OVARIAN GRANULOSA-THECA CELL TUMOR IN A HORSE, Journal of the American Veterinary Medical Association, 212(9), 1998, pp. 1419
Lymphoma is the most common hematopoietic tumor of horses, with the su
bcutaneous form developing fairly often. Subcutaneous lymphoma in hors
es is often T-cell rich B-cell lymphoma. In horses, subcutaneous lymph
omas often have a waxing and waning nature that may be related to cycl
ic changes in serum steroid hormone concentrations.
