Chardonnay has at least a two-year history of recurrent pruritus and pyoderma per the PDVM notes, but the owner’s main concern over the last 6 months is a worsening rash and sores that don’t seem to be responding to treatment. The owner is concerned that some of the lesions may be blisters. PDVM notes indicated a concern for a possible suture reaction post OHE (stainless steel sutures had been used), but a revision surgery to remove these sutures was performed and problems persist nevertheless. Chardonnay has been on multiple rounds of systemic antibiotics and steroids, as well as topical Betagen (betamethasone/gentamicin spray) twice daily for the last 4 months. Owner had also tried bathing with a 3% chlorhexidine shampoo (Douxo PYO) to no effect. A topical lidocaine spray (also containing hydrocortisone) seemed to help some per owner. The owner’s brother owns one of Chardonnay’s littermates who has no such issues. Current diet is Diamond Naturals Salmon and Potato with no digestive problems noted, and current flea and tick prevention is Bravecto. Puritus level was fairly high (7.5/10 per owner).
Physical Exam
There is marked dermal atrophy of the ventral abdomen, groin, and thighs, with TNTC comedones and milia present, and ulcerated sores present on the medial thighs bilaterally (see images below). The rest of the exam is WNL.
Diagnostics
Cytology of the ventral abdomen revealed TNTC streaming neutrophils with 0-5 cocci per oil immersion field.
Assessment
Severe dermal atrophy with erosion/ulceration secondary to Betagen Spray overuse, with mild secondary staphylococcal pyoderma
