Electrochemotherapy for the treatment of basal cell tumours of the nasal planum in three cats

Abstract

Case series summary Malignant basal cell tumours may be seen on or near the nasal planum in cats, and include basal cell carcinomas, which are common, and basosquamous carcinomas, which are rare. Reported treatments for these tumours include surgical excision, radiotherapy, photodynamic therapy and cryosurgery. This report describes the successful management of basal cell tumours with electrochemotherapy (ECT), including calcium electroporation, in three cats. Relevance and novel information All patients had a complete response lasting at least 9 months to 1 year. The adverse effects of this treatment were minimal and were limited to nasal discharge, sneezing and scabs at the treatment site. ECT and calcium electroporation are a safe, minimally invasive and effective option for the treatment of feline basal cell carcinoma and basosquamous carcinomas.
