Parathyromatosis is characterized by multiple lesions of benign hyperfunctioning parathyroid tissue in the neck or mediastinum. Parathyromatosis is caused by proliferation of embryonic remnant or seeding of parathyroid tissue after parathyroidectomy. Parathyromatosis is rare but is the common cause of recurrent hyperparathyroidism. https://www.fitnessgravesyardes.shop/product-category/brake-wire/
