Two unusual tumours in a ferret (Mustela putorius furo).

This case report describes the clinical history, diagnosis and treatment of a ferret with a tumour of the right adrenal gland and insulinomas of the pancreas. Histopathology of both lesions confirmed the diagnoses. Clinical signs of the adrenal gland tumour were a swollen vulva, overgrooming, sexual activity and pruritus. The clinical signs suggesting insulinomas were collapse of the ferret, disorientation and ptyalism. A low blood glucose level assisted the diagnosis of insulinomas. This is believed to be the first reported case of concurrent insulinomas and adrenal gland tumour in a ferret in the United Kingdom.
