Digital trichoblastoma treated with electrochemotherapy in a dog

Abstract

Canine trichoblastoma is a benign tumour derived from the trichoblastic epithelium, commonly affecting the head and neck and, less commonly, the limbs and trunk. Herein, the authors report a case of a dog with digital trichoblastoma successfully treated with electrochemotherapy (ECT). The dog received three sessions of ECT with systemic bleomycin. The tumour volume decreased throughout the ECT sessions, with a complete response after 81 days. The patient presented a disease-free survival of 700 days. ECT may be a better approach than surgery for digital trichoblastomas because it avoids amputating the digit and provides a good cosmetic result.
