Onychodystrophy

Symmetric lupoid onychodystrophy is a form of lupus that involves the cells from which the nails grow.

Whether onychodystrophy is more common among patients with diabetes is not known.

Median canaliform onychodystrophy typically presents with the Heller's fir tree deformity and is often associated with severe arterial disease, severe malnutrition, and trauma.

There is no tissue crepitus but some scaliness of the surrounding plantar skin. There is onychodystrophy suggestive of onychomycosis affecting four of his nine toenails.

Again, it is important to include in this category only those dogs that developed onychodystrophy as the initial clinical manifestation of their disease, not as a result of onychomadesis, onycholysis, and so forth.
