Non‐secreting parathyroid carcinoma in a dog. Issue 1 (23rd December 2021) - Tremolada, Giovanni
Abstract: Parathyroid carcinoma is a rare condition affecting dogs. These tumour types are most commonly not palpable on physical exam and cause hypercalcaemia. Patients with this tumour usually present for clinical signs related to their hypercalcaemic status. This case report describes the first case of a dog with a palpable ventral cervical mass diagnosed as a non‐secreting parathyroid carcinoma. After surgical excision and adjuvant chemotherapy, the dog was alive and presumed disease‐free 16 months after surgery. The prognosis in the dog presented here with non‐secreting parathyroid carcinoma seems to be favourable, but the role of adjunctive chemotherapy is still uncertain. A non‐secreting parathyroid carcinoma should be included as a differential diagnosis in dogs presenting with a ventral cervical mass and no evidence of hypercalcaemia.
