[Cutaneous calcinosis of the footpads in a cat]

Abstract

A case of cutaneous calcinosis of the footpads in a cat is described. The animal had developed lameness of one hindleg which was presumably due to infection by an abscess-like lesion of one pad. Histologically the lesion proved to be based on a cutaneous calcinosis. Shortly afterwards the animal died of uremia. Post mortem examination revealed fine granular shrinkage of the kidneys and signs of demineralisation of the skeleton accompanied by calcifications in the pads of all four paws, major arteries, hear, kidneys, lung and gastric mucosa. The clinical and morphological findings suggest a cutaneous calcinosis of the footpads as an additional localisation of extraosseous calcification in osteorenal syndrome.
