[Epidermolysis bullosa in a calf].

A four-week-old Simmental x Red Holstein calf had lesions of skin and oral mucosa since its first days of life. Where skin or mucosa was exposed to minimal trauma as in oral cavity or over joints, it broke off, forming blisters and erosions. The diagnosis of epidermolysis bullosa, a hereditary disease, was based on clinical and histological findings. Histology pointed to the epidermal form of epidermolysis bullosa, comparable to epidermolysis bullosa simplex in humans.
