Not a disease — rather, a clinical presentation |
Common presentation in general practice and referral dermatology practice |
Underlying primary condition is present |
Allergic disease is a common primary cause |
May or may not be accompanied by other dermatologic symptoms |
May or may not be accompanied by systemic clinical symptoms |
Not every patient with predisposing factors is affected in the absence of primary disease |
Symptoms/visual lesions at the affected site may or may not indicate primary disease |
Inflammation and discomfort (including pruritus) are common |
Secondary infection is common |
Inflammation alone does not indicate infection |
Cytological testing helps confirm or rule out secondary infection (except in deeper infection or with presence of chronic changes) |
Secondary infection(s) complicate treatment and clinical picture |
Affects patient quality of life |
Frustrating condition for pet owners |
Frustrating condition for veterinarians |
Potential for chronicity, leading to further complications |
Chronic changes complicate treatment and clinical picture |
Ongoing maintenance therapy to control secondary and perpetuating factors may be required |
Perpetuating factors may prevent symptom resolution even with primary disease controlled |
Secondary unresolved infection may act as a perpetuating factor |
