An equine melanoma is a tumor that results from the abnormal growth of melanocytes in horses. Unlike in humans, melanomas in horses are not thought to be caused by exposure to ultraviolet light. [1] Melanomas are the third most common type of skin cancer in horses, with sarcoids being the first most prevalent and squamous-cell carcinoma being ...

Five more horses have died at a barn at Los Alamitos, bringing the total to 12 deaths as a result of an outbreak of equine infectious anemia.
The disease has a similar cause to Hirschsprung's disease in humans. A mutation in the middle of the endothelin receptor type B ( EDNRB ) gene causes lethal white syndrome when homozygous . Carriers, which are heterozygous —that is, have one copy of the mutated allele , but themselves are healthy—can now be reliably identified with a DNA test .
Treatment of Cushing's depends on the cause. It is possible to cure Cushing's if the tumour is small, benign, and located on the adrenal gland; however, this is not common. [2] [6] Hypophysectomy is an option for patients with good clinical signs and a high life expectancy. Inoperable pituitary tumours may be treated with radiation, this is ...
