Symptoms & Treatment of Dog's Eosinophilic Granuloma Di

Diagnosis: A tissue biopsy from the affected area was subjected to histopathological examination. Under the microscope, a diffuse infiltration of eosinophils and collagen degeneration were observed within the dermal layer. There was also a significant presence of lymphocytes and a small number of columnar epithelial cells.

Treatment: The dog was prescribed oral prednisone, with a dosage of 50mg per day (equivalent to 2.2mg/kg based on its weight), to be taken continuously for three weeks. Following this, the dosage was reduced to 25mg daily, with an additional 25mg taken every other day, and then 15mg daily. Each of these regimens was maintained for a week.

When the skin is infected by fungi, distinct circular patches of alopecia, exudation, and crusting may appear. The infected skin shows clearly demarcated focal or multifocal plaques, with symptoms such as hair loss, hair breakage, dandruff, pustules, papules, fluid exudation, and crust formation. The degree of itching can vary significantly.

In cases of eosinophilic granuloma, a Woods lamp examination will yield negative results, and no hyphae or spores can be observed under microscopic examination. Topical antifungal treatments will be ineffective. When infected with mites, the presence of the mite or its eggs can be observed under the microscope. Despite the presence of a high number of eosinophils in tissue sections when the skin is infested with mites, no mites or eggs are visible in the skin scrapings of patients with eosinophilic granuloma.
