In suspected hepatocutaneous syndrome take early, mild lesions (not chronic ulceration). If you cannot find a pustule, take a small crusted lesion that looks recent. If there are lesions on the face or trunk, find a lesion that looks like a small pustule.
If the animal has ONLY footpad lesions, try to obtain a specimen from the edge of a pad that looks like it is just starting to peel off. In pemphigus, it is difficult to obtain good samples from the footpads.

The key to obtaining a diagnostic skin biopsy is to take samples of early lesions. In hepatocutaneous syndrome, they may be normal or abnormal, depending on the nature of the liver disease. Radiographic or abdominal ultrasound examinations are normal in pemphigus.
In pemphigus, the results are generally quite normal in hepatocutaneous syndrome, liver enzymes are usually elevated, and there may be anemia, hyperglycemia, hypoalbuminemia, and increased serum bile acid levels. Laboratory and radiographic evaluations are useful in differentiating these syndromes. Metatarsal fistulation of German Shepherd Dogs involves the metatarsal pads, but typically not the digital pads. Zinc responsive dermatosis frequently produces hyperkeratosis of the footpads and face usually this is in younger dogs of the Arctic breeds. There is sometimes pain and difficulty walking.ĭifferential diagnoses for footpad diseases include other uncommon skin diseases such as canine distemper. The skin lesions consist of erosions, ulcerations, and fissuring of the skin of the muzzle, mucocutaneous areas of the face, distal limbs, and footpads. Many dogs with this syndrome are diabetic. ANY liver disease can be associated with hepatocutaneous syndrome. This syndrome is a metabolic disease of uncertain pathogenesis. Hepatocutaneous syndrome is a rare syndrome where distinctive skin lesions are present along with one of several types of liver disease. Many animals have affected footpads, with peeling, scaling, and crusting lesions in layers. The lesions typically are found on the bridge of the nose, face, ears, mucocutaneous junctions, and trunk. The primary lesions develop and burst rapidly, leaving behind circular areas of scaling, crusting, and hair loss. In pemphigus foliaceus, the primary lesion is a superficial pustule or bulla. Pemphigus is a group of autoimmune skin diseases in which autoantibodies are present, directed against intercellular "glue" between epidermal cells. PROBLEM: DISEASE INVOLVES MOSTLY THE FOOTPADS These conditions typically fall into four categories: (1) diseases mostly involving the footpads (2) diseases mostly involving the interdigital areas (3) diseases mostly involving the claw or nailbed and (4) diseases mostly involving pedal pruritus. Skin diseases prominently involving the feet, footpads, and nails are a challenge to diagnose and treat.
