Medical records of 30 dogs with histologically confirmed sebaceous adenitis that were treated with isotretinoin or etretinate were reviewed. Akitas and Standard Poodles were overrepresented, compared with the general hospital population. Thirteen dogs had concurrent pyoderma. The retinoids were administered for a minimum of 2 months. Dosage for the 13 dogs treated with isotretinoin only ranged from 0.8 to 3.5 mg/kg of body weight/d (mean, 1.4 mg/kg/d). Dosage for the 10 dogs treated with etretinate only ranged from 0.7 to 1.8 mg/kg/d (mean, 1.1 mg/kg/d). Two dogs were first given isotretinoin (mean dosage, 1.5 mg/kg/d) and, when they did not respond, were subsequently given etretinate (mean dosage, 0.85 mg/kg/d). Five dogs were first given etretinate (mean dosage, 1 mg/kg/d) and, when they did not respond, were subsequently given isotretinoin (mean dosage, 1.6 mg/kg/d. For the 20 dogs treated with isotretinoin, 1 was lost to follow-up; 9 of the remaining 19 had a successful outcome (> 50% reduction in severity of scaling and extent of alopecia, compared with pretreatment appearance). For the 17 dogs treated with etretinate, 9 had a successful outcome. Outcome could not be predicted on the basis of clinical signs or histologic findings, and a prognosis could not be determined on the basis of whether sebaceous glands were evident histologically.
