Tuberculous granulomatous inflammation of parathyroid adenoma manifested as primary hyperparathyroidism: A case report and a review of the literature

Tuberculosis of the thyroid gland is rare, and tuberculous granulomatous inflammation of the parathyroid glands is even rarer. The present study reports a rare case of primary hyperparathyroidism caused by tuberculous granulomatous inflammation. A 58-year-old female patient presented with generalized body pain persisting for 1 year.
