She had a history of two times parathyroidectomy. In recent hospitalization, she presented with the complaint of weakness, bone pain and a progressive swelling in her jaw. Laboratory analysis showed a hypercalcemia and plasma PTH of 398 pg\/ml. Dual energy X-ray (DXA) showed osteoporosis at the neck of hip and lumbar spine. The neck MRI revealed an 11 * 6 mm soft tissue nodule posterior to left thyroid lobe and a 20*18 mm T2 hypersignal, T1hyposignal nodule at right thyroid lobe. The SPECT-CT scintigraphy with 99mTc-MIBI was suggestive of bilateral parathyroid adenomas and\/or parathyroid hyperplasia and showed a MIBI- avid lytic lesion in the mandible. Surgical management was performed. After removing the adenoma the PTH marked a decrease from the initial value to 57 pg\/ml. The histological examination revealed the thyroid tissue with MNG and a left parathyroid adenoma. Follow-up after surgery revealed normal blood calcium and urine calcium levels with no increase. PTH levels also did not increase. The patient was treated with calcium and vitamin D supplements and the jaw mass decreased gradually.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Primary or secondary HPT may be recognized by the presence of an osteolytic lesion with giant cells, a condition referred as brown tumor. Consideration should be made that non-specificity of hypercalcemia symptoms can also be a bone tumor including jaw lesion as a manifestation of hyperparathyroidism.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2018.09.035","type":"journal-article","created":{"date-parts":[[2018,10,4]],"date-time":"2018-10-04T13:03:26Z","timestamp":1538658206000},"page":"54-58","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":5,"title":["Jaw tumor in recurrent primary hyperparathyroidism"],"prefix":"10.1097","volume":"52","author":[{"given":"Farzaneh","family":"Amini Nezhad","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moloud","family":"Payab","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Nayebandi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shirin","family":"Hasani-Ranjbar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-13-20260114","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1590\/S0004-27302012000600009","article-title":"Persistent primary hyperparathyroidism: an uncommon location for an ectopic gland-case report and review","volume":"56","author":"Gouveia","year":"2012","journal-title":"Arq.
