It has been extimated that melanomas represent 6 to 15% of skin tumours seen in horses. Melanomas are the most frequently dermoepidermal and subcutaneus tumors occurring in horses, particularly in gray-skinned horses. The incidence of these tumors increases with age, however, they can be found even at younger ages. More than 90% of these tumors are benign at initial presentation, but approximately two-thirds are thought to progress to malignancy and are capable of widespread metastasis. Althought these lesions are normally limited to the dermis, melanomas can metastatize.

Abstract
It has been extimated that melanomas represent 6 to 15% of skin tumours seen in horses. Melanomas are the most frequently dermoepidermal and subcutaneus tumors occurring in horses, particularly in gray-skinned horses. The incidence of these tumors increases with age, however, they can be found even at younger ages. More than 90% of these tumors are benign at initial presentation, but approximately two-thirds are thought to progress to malignancy and are capable of widespread metastasis. Althought these lesions are normally limited to the dermis, melanomas can metastatize. The current report describes a case of malignant melanoma in an aged grey riding pony, with extramedullary metastasis.Pubblicazioni consigliate
