Concurrent parathyroid carcinoma and adenoma: A rare presentation of a rarer disease entity

Parathyroid carcinoma is a rare disease. But multiglandular parathyroid neoplasm is even rarer. A high level of suspicion, on the basis of clinical, hematological tests and intraoperative findings is necessary to treat this disease entity, particularly in the absence of palpable neck masses. Preoperative localization is important. Bilateral neck exploration should be done routinely and all 4 glands seen to avoid missing out other pathological glands.
