Definition

Tumors of parathyroid origin that arise within, extend into, or metastasize to involve the mediastinum.

Clinical Features

  • Incidence

    Ten percent of parathyroid adenomas are ectopic. Approximately, half of all ectopic parathyroid adenomas occur in the anterior mediastinum due to embryologic origin from the third and fourth branchial pouches. Mediastinal parathyroid carcinoma is rare.

  • Age

    Mediastinal parathyroid tumors can be seen in any age group. The peak incidence of symptomatic parathyroid adenoma is between 50 and 60 years of age. Parathyroid carcinoma can occur at any age.

  • Sex

    Parathyroid adenomas and cysts occur more often in women. Gender distribution is equal in parathyroid carcinoma.

  • Site

    Ectopic parathyroid tumors are more common in the anterior mediastinum; however, posterior mediastinal tumors are well documented.

  • Treatment
