Three cases of melanoma in small ruminants: Clinical symptoms and pathological results

This paper reports the pathological findings of three melanocytic tumours in small rumi-nants located in the right external concha of the ear and at the base of the horn.Macroscopically the masses were dark brown-black in colour and showed necrotic surfacesand ulceration. Microscopically pleomorphic cells were observed in the dermis and at theepidermal–dermal junction. No metastasis were detected, but on the basis of morphologicalcriteria the reported cases were classified as malignant neoplasiae.
