• d. erythematosa — a disease of unknown etiology which occurs in pigs, mainly the white varieties; there is nonpruritic, acute erythema over large areas of the body and spontaneous recovery occurs in a matter of days.
• exfoliative d. — one involving severe desquamation; includes drug reaction, contact hypersensitivity, autoimmune diseases, cutaneous lymphomas and parapsoriasis.
• generic dog food d. — see generic pet food.
• growth hormone-responsive d. — see growth hormone-responsive dermatosis.
• hereditary lupoid d. — a scaling and crusting skin disease seen from a young age in German shorthaired pointers.
• infantile pustular d. — pustules, depression and anorexia in neonatal puppies; the etiology is unknown.
• invisible d. — skin diseases which are evident clinically, but the histopathology is consistent with normal skin.
• linear IgA d. — a rare, immune-mediated skin disease of Dachshunds in which immunoglobulin A is deposited at the basement membrane zone. There are pustules, with alopecia, hyperpigmentation, scaling and crusting.
• linear preputial d. — a narrow line of hyperpigmentation along the midline between the prepuce and scrotum is considered a marker for testicular neoplasia in dogs.
• psychogenic d. — one caused by self-trauma for which no cause is known; in dogs and cats, boredom, overcrowding or confinement are often associated. See idopathic hyperesthesia syndrome, acral lick dermatitis, flank sucking, tail sucking.
• seborrheic d. — see seborrheic dermatitis.
• subcorneal pustular d. — a very rare skin disorder of dogs in which short-lived, sterile, superficial pustules form, particularly on the head and trunk. Pruritus is variable. The cause is unknown.
• ulcerative d. — see ulcerative dermatosis.
• d. vegetans — an inherited skin disease of Landrace pigs. Young piglets may be affected at birth or develop at an early age an erythematous, papular dermatitis, mainly on the ventral abdomen and medial thighs. There is also erythema and edema of the coronary bands and subsequent deformities of the foot. Pneumonia develops before death.
• zinc-responsive d. — a breed-related form occurs in Siberian huskies and several other Artic breeds, and a dermatosis can occur in puppies of any breed if their diet is deficient in zinc or absorption is impaired by excessive supplementation of calcium. There is scaling and crusting, especially over pressure points and footpads. See also parakeratosis for a similar disease in pigs and a familial one in cattle.
