A 8 kg, 3-year-old male West Highland white terrier dog with a 1.5-year history of chronic, severely pruritic, seborrheic skin disorder was referred to the Veterinary Medical Teaching Hospital of the Tokyo University of Agriculture and Technology. On physical examination, lesions were observed on entire cutaneous surface, except for face, dorsum of body, and footpads. Skin lesions were characterized by diffuse erythema, erythematous papules, severe alopecia, hyperpigmentation, and lichenification. Tape strip tests of skin lesions revealed cocci and Malassezia infections. The intradermal allergy tests revealed positive reactions to Japanese cedar pollen, but the non-seasonal clinical signs were not compatible with atopic dermatitis caused by this pollen. Results of hematological examination, serum chemistry and thyroid gland profile were normal. Examination of skin biopsy exhibited hyperplastic superficial perivascular dermatosis with severe acanthosis, excessive keratinocyte mitoses, patchy or diffuse mild spongiosis, and lymphocytic exocytosis in epidermis. Perivascular to interstitial mononuclear cells infiltration was seen in the superficial dermis. Based on the results of examination described above, epidermal dysplasia was diagnosed. Treatments with administration of antibiotics, etretinate, and prednisolone orally combined with topical ketoconazole cream and antiseborreic shampoos had no good results. Following treatment with long-term oral itraconazole at 10 mg/kg daily and chlorhexidine shampoos was successful. However, when itraconazole therapy was stopped, the condition worsened twice within 2 or 3 months. Readministration of itraconazole produced improvement within 4 weeks. This dog has now been controlled periodical itraconazole therapy.

A 9-month-old, 11.3 kg, intact, male, mixed-breed dog was referred for treatment of cor triatriatum dexter (CTD); a 5-month-old, 1.9 kg, intact, male Maltese for pulmonic stenosis (PS); and a 3-year-old, 6.62 kg, intact, female West Highland white terrier for esophageal stricture with regurgitation. A balloon catheter intervention was performed in the dog with CTD, and subsequent color Doppler ultrasound and abdominal ultrasound showed normal blood flow across the perforated membrane dividing the right atrium and the disappearance of the severe ascites present before treatment. Balloon catheter intervention in the dog with PS reduced the blood flow through the stenosis from 5.82 m/s to 3.97 m/s. In the dog with esophageal stricture, balloon catheter intervention widened the esophagus and no subsequent regurgitation was observed. Balloon catheter intervention is an interventional radiology procedure that represents a definitive treatment option for various stenotic lesions in dogs, including CTD, PS, and esophageal stricture. Although interventional radiology procedures for these diseases have already been reported, details of procedures and successful outcome have not been reported in Korea.
