Primary hyperplasia of the parathyroids

Area of Science:

• Endocrinology
• Surgical Pathology
• Neurosurgery

Background:

• Primary hyperparathyroidism is a common endocrine disorder often caused by parathyroid adenoma or hyperplasia.
• Distinguishing between hyperplasia and adenoma is crucial for appropriate surgical management.
• Parathyroid hyperplasia presents a diagnostic challenge, sometimes mimicking adenoma.

Purpose of the Study:

• To report on the surgical outcomes of primary parathyroid hyperplasia.
• To evaluate the efficacy of total parathyroidectomy with parathyroid tissue autotransplantation (PTA).
• To emphasize the importance of thorough parathyroid gland assessment during surgery.

Main Methods:

• Retrospective analysis of eight cases of primary parathyroid hyperplasia among 322 hyperparathyroidism cases.
• Surgical intervention involved total parathyroidectomy with PTA in seven patients.
• Intraoperative frozen section biopsy for gland identification and diagnosis.

Main Results:

• All patients preoperatively presented with hypercalcemia.
• Six cases involved water-clear cell hyperplasia, one chief cell, and one mixed.
• Postoperative follow-up up to six years showed sustained normocalcemia and symptom resolution in surviving patients.
• Two patients required Vitamin D supplementation.

Conclusions:

• Total parathyroidectomy with PTA is a preferred surgical strategy for primary parathyroid hyperplasia over subtotal resection.
• This approach yields satisfactory primary results and facilitates reoperation if recurrence occurs.
• Accurate intraoperative identification and biopsy of all parathyroid glands are critical to avoid misdiagnosis and ensure complete treatment.
