ABSTRACT
A 5 yr old female spayed pit bull terrier mix was evaluated for development of multiple dermal nodules over the previous 2 wk with concurrent weight loss and lethargy. A definitive diagnosis of cutaneous epitheliotropic T-cell lymphoma was obtained through histopathology and immunohistochemistry. Treatment was initiated with 32.9 mg/m2 (1.2 mg/kg) of oral verdinexor twice per week, according to label guidance. One week after treatment initiation, clinical remission was noted with complete resolution of the cutaneous nodules. The dog has continued twice-weekly treatments without any interruption and remains in complete remission 17 mo following initiation of verdinexor therapy. This case provides evidence for the utility of verdinexor in the treatment of canine cutaneous epitheliotropic T-cell lymphoma.
