juvenile pyoderma

a sterile, pustular skin disease on the face and head and sometimes ears, anus and prepuce, in one or more puppies of a litter, usually around weaning age. Dachshunds, Golden retrievers and Gordon setters appear to be predisposed. There is often fever, anorexia and lymphadenopathy, particularly of submandibular lymph nodes which may form abscesses and drain, hence the alternative name of puppy strangles. Staphylococcus spp. are frequently cultured from affected skin, but the etiology of the disease is unclear. Called also juvenile cellulitis, and juvenile sterile granulomatous dermatitis and lymphadenitis.

mucocutaneous pyoderma

occurs on the lip margins and perioral skin of dogs; German shepherd dogs are predisposed.

nasal pyoderma

a deep bacterial folliculitis and furunculosis on the dorsum of the nose in dogs, particularly German shepherd dogs, Bull terriers, Collies and Pointers. Trauma may be a factor in the etiology.

Dermatology A rare idiopathic condition characterized by skin ulceration; at least 50% of Pts have associated systemic disease, including infection, malignancy, vasculitis, collagen vascular diseases, DM, trauma Clinical An initial bite-like lesion, pain, arthralgias and malaise; the classic ulcers occur on the legs; a superficial variant, atypical PG, tends to occur on the hands; involvement of other organ systems manifests as sterile neutrophilic abscesses in the lungs, heart, CNS, GI tract, eyes, liver, spleen, bone, and lymph nodes Associated conditions IBD–either ulcerative colitis or Crohn's disease, a symmetric polyarthritis,  hematologic disorders–eg, leukemia or preleukemia, predominantly myelocytic, monoclonal gammopathies, especially IgA gammopathy; less common associations include arthritides–eg, psoriatic arthritis, osteoarthritis, or spondyloarthropathy; liver disease–eg, hepatitis and primary biliary cirrhosis; myeloma–especially IgA type and immunologic diseases–eg, SLE, Sjögren's DiffDx Acute febrile neutrophilic dermatosis, aphthous stomatitis, atrophie blanche, Behçet disease, chancroid, Churg-Strauss syndrome–allergic granulomatosis, ecthyma, ecthyma gangrenosum, herpes simplex, hypersensitivity vasculitis–leukocytoclastic vasculitis, impetigo, insect bites, sporotrichosis, SCC, venous insufficiency, verrucous carcinoma, Wegener's granulomatosis Management Anti-inflammatories–eg, corticosteroids, immunosuppressants
