Parathyroid adenoma in submucosa of esophagus.

We recently excised and examined a parathyroid adenoma that was located in the submucosa of the esophagus. It was discovered when an elevated calcium level was found on a screening chemistry profile. Subsequently, the patient was found to have renal stones. At operation two other small parathyroid glands were identified. A fourth one was not found. Following removal of the adenoma, the patient's calcium level returned to normal and has remained normal for several months.
