title: A parathyroid myxoadenoma observed grossly.
abstract: We are reporting a case of a patient with primary hyperparathyroidism because of an unusual parathyroid adenoma. The tumor had an extensive myxofibrous stroma without an identifiable lipomatous component. Though moderate to extensive myxoid alteration of the stroma has been reported in lipoadenomas, to the best of our knowledge, this is the first parathyroid adenoma in which the myxomatous component was recognized grossly and which lacked a stromal adipose component.
