It is a parathyroid tumor with atypical histological features different from an adenoma and not similar enough to be considered as a carcinoma. It has an uncertain malignant potential. We report the case of a 55\u2010year\u2010old woman, diagnosed with severe hypercalcemia during her follow\u2010up with the rheumatologist for osteoporosis. The laboratory testing led to the detection of a very important level of parathormone PTH 1325.62\u2009pg\/ml (20 fold the normal level), confirming the diagnosis of primary hyperparathyroidism. Investigations of the potential causes led to the presence of a large left inferior parathyroid adenoma. The patient was operated and on the examination of the removed tissue, the histopathological examination concluded to an atypical parathyroid adenoma, and the post\u2010operatory PTH level dropped significantly to 152\u2009pg\/ml. The atypical parathyroid adenoma is a very rare tumor, and the diagnosis is still a challenge, the outcome of patients is not well known yet, there for the surveillance is important and must be regularly.<\/jats:p>","DOI":"10.1002\/ccr3.6785","type":"journal-article","created":{"date-parts":[[2022,12,22]],"date-time":"2022-12-22T23:10:20Z","timestamp":1671750620000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Atypical parathyroid adenoma: A case report"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8990-680X","authenticated-orcid":false,"given":"Chayma","family":"Besrour","sequence":"first","affiliation":[{"name":"Department of Endocrinology Charles Nicolle Hospital  Tunis Tunisia"},{"name":"Faculty of Medicine of Tunis Tunis El Manar University  Tunis Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4500-9020","authenticated-orcid":false,"given":"Imen","family":"Rojbi","sequence":"additional","affiliation":[{"name":"Department of Endocrinology Charles Nicolle Hospital  Tunis Tunisia"},{"name":"Faculty of Medicine of Tunis Tunis El Manar University  Tunis Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadia","family":"Mchirgui","sequence":"additional","affiliation":[{"name":"Department of Endocrinology Charles Nicolle Hospital  Tunis Tunisia"},{"name":"Faculty of Medicine of Tunis Tunis El Manar University  Tunis Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ibtissem","family":"Ben Nacef","sequence":"additional","affiliation":[{"name":"Department of Endocrinology Charles Nicolle Hospital  Tunis Tunisia"},{"name":"Faculty of Medicine of Tunis Tunis El Manar University  Tunis Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karima","family":"Khiari","sequence":"additional","affiliation":[{"name":"Department of Endocrinology Charles Nicolle Hospital  Tunis Tunisia"},{"name":"Faculty of Medicine of Tunis Tunis El Manar University  Tunis Tunisia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,12,22]]},"reference":[{"key":"e_1_2_10_2_2_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12957-021-02123-7"},{"key":"e_1_2_10_2_3_1","doi-asserted-by":"publisher","DOI":"10.1530\/ERC-19-0135"},{"key":"e_1_2_10_2_4_1","unstructured":"SFEndocrino.
