[A horse with a badly-healing wound? A case report]. / Een paard met een slecht genezende wond? Een case report.

A 14-year-old Haflinger mare was presented with a wound on the right metatarsus which it had sustained 3 years earlier. The wound had never completely healed but had only recently become a problem. Over a period of several months, the wound became larger, produced a lot of exudate, and the horse became lame on the affected limb. Clinical examination and radiographs failed to reveal the cause of the deterioration. Histological evaluation of tissue removed during debridement of the wound revealed squamous cell carcinoma. Because the tumour had already invaded the bone, the prognosis was unfavourable and the horse was euthanised. Necropsy showed the tumour to have metastasised to the right inguinal area and the adjacent mammary gland.
