    This case highlights a rare posterior mediastinal tumor caused by an ectopic parathyroid adenoma. Managing such unusual cases of hyperparathyroidism can be challenging due to atypical adenoma location.

    Area of Science:

    • Endocrinology
    • Surgical Pathology
    • Nephrology

    Background:

    • Hyperparathyroidism is a condition characterized by excessive parathyroid hormone production, often leading to hypercalcemia.
    • Common causes include parathyroid adenomas, hyperplasia, or carcinoma, typically located in the neck.
    • Ectopic parathyroid adenomas, though rare, can occur in various locations, complicating diagnosis and treatment.

    Observation:

    • A patient with peptic ulcer disease and nephrolithiasis presented with persistent hypercalcemia despite initial neck exploration.
    • A two-year follow-up revealed a retroesophageal mass.
    • The mass was diagnosed as a parathyroid adenoma.

    Findings:

    • The parathyroid adenoma was located ectopically in the posterior mediastinum, presenting as a retroesophageal tumor.

  • Persistent hypercalcemia post-neck exploration indicated the presence of unaddressed or ectopic parathyroid tissue.
  • Diagnostic challenges were encountered due to the unusual location of the adenoma.

    • Implications:

    • This case underscores the importance of considering ectopic parathyroid tissue in persistent hypercalcemia, even after negative neck exploration.
    • It highlights the diagnostic and surgical difficulties associated with managing posterior mediastinal parathyroid adenomas.
    • Awareness of such rare presentations is crucial for effective patient management and improved outcomes in hyperparathyroidism.
