| |
− | * Non-endocrine tumours may be capable of secreting hormones, or hormone-like factors.
| |
− | ** A parathormone-like substance may be secreted in such a manner.
| |
− | ===Apocrine Gland Adenocarcinoma===
| |
− | * Malignant tumours of the anal sac apocrine glands can produce PTH-related peptide (PTHrp).
| |
− | ** This induces a pseudo-hyperparathyroidism and hypercalcaemia.

| |
− | * 10 to 40% of cases in dogs may cause a pseudo-hyperparathyroidism.
| |
− | ===Other Carcinomas===
| |
− | Some other carcinomas may also be capable of causing pseudo-hyperparathyroidism.

− | ==[[Hypoparathyroidism]]==
| |
− | * Hypoparathyroidism may result from primary gland hypofunction.
| |
− | ** Gland hypofunction occurs due to:
| |
− | **# Destruction of secretory cells by a disease process.
| |
− | **#* For example, this may be immune mediated, or another inflammatory cause.
| |
− | **# A biochemical defect in synthetic pathway of the hormone.
| |
− | **#* These are usually genetic aberrations.
| |
− | **#* Defects in synthesis are not commonly identified in the veterinary species.
