Here, we report a case of hypercalcemia in a patient with acute pancreatitis, subsequently diagnosed with FHH. A 41-year-old male presented with abdominal pain and elevated pancreatic enzymes. Imaging revealed changes consistent with acute pancreatitis. Surprisingly, serum calcium was elevated, which is uncommon in acute pancreatitis. Further work-up demonstrated normal parathyroid hormone (PTH), PTH-related peptide (PTHrp), and vitamin D levels. A 24- hour urinary calcium excretion of 24 mg\/24 hr and a calcium-to-creatinine clearance ratio (CCCR) of 0.002 confirmed the diagnosis of FHH. This condition is typically asymptomatic, with few complications, and is managed conservatively with patient education and genetic counselling.<\/jats:p>","DOI":"10.55729\/2000-9666.1497","type":"journal-article","created":{"date-parts":[[2025,7,7]],"date-time":"2025-07-07T08:54:13Z","timestamp":1751878453000},"page":"66-68","source":"Crossref","is-referenced-by-count":1,"title":["A rare case of Familial hypocalciuric hypercalcemia in patient with pancreatitis"],"prefix":"10.55729","volume":"15","author":[{"given":"Muhammad Ijaz","family":"Khan","sequence":"first","affiliation":[{"name":"Greater Baltimore Medical Centre, Towson, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanvi","family":"Jain","sequence":"additional","affiliation":[{"name":"Greater Baltimore Medical Centre, Towson, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad Mohsin","family":"Abid","sequence":"additional","affiliation":[{"name":"Greater Baltimore Medical Centre, Towson, MD, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samra","family":"Israr","sequence":"additional","affiliation":[{"name":"Khyber Medical College, Peshawar, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad Haris","family":"Khan","sequence":"additional","affiliation":[{"name":"Khyber Medical College, Peshawar, Pakistan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"34701","published-online":{"date-parts":[[2025,7,3]]},"container-title":["Journal of Community Hospital Internal Medicine Perspectives"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/scholarlycommons.gbmc.org\/cgi\/viewcontent.cgi?article=1497&amp;context=jchimp","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,5]],"date-time":"2026-09-05T09:55:05Z","timestamp":1788602105000},"score":1,"resource":{"primary":{"URL":"https:\/\/scholarlycommons.gbmc.org\/jchimp\/vol15\/iss4\/15"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7,3]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2025,7,3]]}},"URL":"https:\/\/doi.org\/10.55729\/2000-9666.1497","relation":{},"ISSN":["2000-9666"],"issn-type":[{"value":"2000-9666","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,7,3]]}}}
