Plain-English summary
Four mares were diagnosed with mammary gland adenocarcinoma, a type of cancer in the breast tissue. They showed signs like firm swelling of the mammary gland and a discharge that was bloody and watery coming from the teat. Two of the mares also had sores on their mammary glands, and touching the affected area caused them pain. To confirm the diagnosis, vets looked at the fluid from the discharge under a microscope and also examined tissue samples. The treatment involved surgically removing the affected mammary gland and nearby lymph nodes.
Abstract
Mammary gland adenocarcinoma in 4 horses was characterized by firm swelling of the gland and serosanguineous discharge from the teat orifice. Two of the mares had ulcerative lesions of the mammary gland. Palpation of the affected gland typically elicited signs of pain. Diagnosis was assisted by cytologic evaluation of the fluid discharge, but definitive diagnosis was based on histologic examination. Treatment included mastectomy and lymphadenectomy.
