Oncocytic Parathyroid Adenoma Associated with Primary Hyperparathyroidism: A Case Report

• Go JH

Abstract

A rare case of functioning oncocytic parathyroid adenoma associated with primary hyperparathyroidism was found in a 45-year-old woman. The preoperative serum calcium level was 13.1 mg/dL, the phosphate level was 2.44 mg/dL and the parathyroid hormone level was 153 pg/mL. Neck CT revealed a 2.5x1x1 cm, well enhanced mass behind the left thyroid gland, which was compatible with parathyroid adenoma. The removed parathyroid gland showed a well circumscribed, ovoid, brown colored, soft, solid mass. Histologically, this mass was composed of broad sheets of uniform cells having round dense nuclei and abundant eosinophilic granular cytoplasms. The adjacent rim of the normal parathyroid tissue was identified in the periphery of the mass. After operation, all hormone levels were normalized.
