Spontaneous resolution of hypercalcemia.

BACKGROUND

Primary hyperparathyroidism (PHPT) is a frequently encountered endocrine disorder due to benign neoplastic lesions or gland hyperplasia. It is often discovered incidentally when routine lab work reveals hypercalcemia.

METHODS

This case presents a 55-year-old male with a neck mass and electrolyte irregularities consistent with PHPT. However, his laboratory values suddenly normalized prior to surgery.

RESULTS

Post-operative pathologic analysis of the specimen demonstrated massive infarction of the affected gland, and explained the spontaneous resolution of the patient's electrolyte derangements.

CONCLUSIONS

The objective of this case study is to demonstrate the importance of further investigation in patients with fluctuating lab values and emphasize the potential dangers of gland infarction.
