Plain-English summary
A horse was brought in because it was limping due to pain in its shoulder. X-rays and a special imaging test helped find a problem in the upper arm bone, but the horse later showed other signs of illness, which led to more tests. Blood tests, urine tests, and an ultrasound revealed that there was a mass near the kidneys causing kidney failure. Because the horse had a very poor outlook for recovery, it was euthanized. A thorough examination after death confirmed the diagnosis of an aggressive cancer that had spread to other organs.
Abstract
We present a case of aggressive metastatic carcinoma in a horse that was initially presented for shoulder lameness. Although radiography and scintigraphy were useful for localising a lesion in the proximal humerus, subsequent development of non-specific signs of systemic disease prompted further evaluation. Haematology and blood biochemistry, urinalysis and ultrasonography were all instrumental in identifying renal involvement. A diagnosis of a peri-renal mass causing secondary renal failure prompted euthanasia of the horse because of the poor prognosis. Antemortem findings were supported by necropsy, with secondary lesions also identified in the spleen, liver, 8th left rib and proximal humerus. Histological examination yielded a diagnosis of undifferentiated metastatic carcinoma.
