Parathyroid sarcoidosis is usually associated with parathyroid adenomas, and, therefore, hypercalcaemia is a common presentation of this entity. We present a case of parathyroid sarcoidosis and review the world literature regarding this rare condition. A woman with a history of diffuse large B cell lymphoma underwent a surveillance positron emission tomography scan that showed increased fluorodeoxyglucose uptake in multiple thoracic and abdominal lymph nodes and in a left upper extremity soft tissue mass. Biopsy of the soft tissue mass showed non-caseating granulomas consistent with sarcoidosis. Blood work showed a serum calcium of 11.1\u2009mg\/dL with an intact serum parathyroid hormone of 92\u2009pg\/dL. Primary hyperparathyroidism was suspected. A neck ultrasound and sestamibi parathyroid scintigraphy demonstrated a parathyroid nodule. She underwent surgical resection, and the histopathology revealed a parathyroid adenoma and non-caseating granulomata consistent with a diagnosis of sarcoidosis.<\/jats:p>","DOI":"10.1136\/bcr-2019-230598","type":"journal-article","created":{"date-parts":[[2019,7,15]],"date-time":"2019-07-15T08:29:26Z","timestamp":1563179366000},"page":"e230598","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":9,"title":["Rare case of parathyroid gland sarcoidosis presenting with hypercalcaemia"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3595-8804","authenticated-orcid":false,"given":"Biplab Kumar","family":"Saha","sequence":"first","affiliation":[{"name":"Pulmonary and Critical Care Medicine, Albany Medical Center Hospital, Albany, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stacey L","family":"Burns","sequence":"additional","affiliation":[{"name":"Anesthesiology, Brigham and Women\u2019s Hospital, Boston, Massachusetts, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Llewellyn A","family":"Foulke","sequence":"additional","affiliation":[{"name":"Department of Pathology, Albany Medical Center, Albany, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc A","family":"Judson","sequence":"additional","affiliation":[{"name":"Pulmonary and Critical Care Medicine, Albany Medical Center Hospital, Albany, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,7,15]]},"reference":[{"key":"2025082710231013000_12.7.e230598.1","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1980.00330220088035"},{"key":"2025082710231013000_12.7.e230598.2","doi-asserted-by":"crossref","first-page":"499","DOI":"10.1016\/0002-9610(81)90383-4","article-title":"Sarcoidosis, hypercalcemia and primary hyperparathyroidism.
