Glucagon‐producingneuroendocrine tumour associated with hypoaminoacidaemia and skin lesions

A nine‐year‐old neutered female crossbred Bernese mountain dog was diagnosed with superficial necrolytic dermatitis and a glucagon‐producing islet cell tumour. Laboratory findings included hyperglucagonaemia and hypoaminoacidaemia. The dog was euthanased because of progression of the disease, and necropsy revealed liver metastases of a neuroendocrine carcinoma with immunohistochemical expression of glucagon and somatostatin. This report represents a case of canine glucagonoma syndrome; the previously reported cases in dogs are also briefly described.
