Management and closure of multiple large cutaneous lesions in a juvenile cat with severe acquired skin fragility syndrome secondary to iatrogenic hyperadrenocorticism.

Abstract

CASE DESCRIPTION A 13-month-old castrated male cat was evaluated for a large, spontaneously developed cutaneous laceration over the left scapular region. The cat had a history of severe gingivostomatitis, conjunctivitis, giardiasis, and feline herpesvirus infection and had received systemic glucocorticoid treatment for 7 weeks prior to evaluation. CLINICAL FINDINGS Physical examination revealed a 10 × 7-cm full-thickness cutaneous laceration over the left scapular region, extremely thin skin, crusts over the dorsal aspect of the neck and base of the skull, medially curling pinnae, and moderate gingivostomatitis. TREATMENT AND OUTCOME Staged wound closure was performed with a combination of daily wound cleaning and debridement, tension and appositional sutures, and wet-to-dry and nonadherent dressings initially with a bacitracin, neomycin, and polymyxin B ointment and then with a 30:1 mixture of silver sulfadiazine and insulin. Multiple additional lesions developed and were treated in the same manner. Complete closure and resolution of all cutaneous lesions was achieved in 9 weeks. CLINICAL RELEVANCE Cats are fairly resistant to the adverse effects of glucocorticoid treatment, and iatrogenic hyperadrenocorticism is rarely reported. This case demonstrated that acquired skin fragility syndrome secondary to iatrogenic hyperadrenocorticism can develop following short-term systemic glucocorticoid administration and that large cutaneous wounds associated with this condition can be successfully managed and closed by means of the reported methods. The prognosis for skin recovery in cats with acquired skin fragility syndrome may be more favorable than previously reported.
