It manifests as a multisystem syndrome, and may be associated with hepatitis B virus-associated PAN (HBV-PAN) although the incidence of this is declining with better vaccination strategies and awareness of bloodborne virus screening. We report a case in which a patient displayed many classical features of the disease, occurring separately over a period of months and leading to contact with various medical specialties. Managing each symptom in isolation led to a number of misdiagnoses (including testicular cancer) and the patient experienced considerable psychological stress and morbidity as a result. The case was complicated by acute pancreatitis developing after an initial treatment response. This may have been iatrogenic (as a consequence of either entecavir or steroids) or secondary to PAN. For our patient, this led to a protracted clinical course but eventual complete resolution of both pathologies.<\/jats:p>","DOI":"10.1136\/bcr-2015-213495","type":"journal-article","created":{"date-parts":[[2016,1,5]],"date-time":"2016-01-05T16:02:42Z","timestamp":1452009762000},"page":"bcr2015213495","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["PAN's labyrinth: a multidisciplinary delayed diagnosis and patient's perspective"],"prefix":"10.1136","volume":"2016","author":[{"given":"Emma Louise","family":"Barlow","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Owen","family":"Seddon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brendan","family":"Healy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2016,1,5]]},"reference":[{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.1","doi-asserted-by":"crossref","first-page":"1088","DOI":"10.1002\/art.1780330805","article-title":"The American College of Rheumatology 1990 criteria for the classification of polyarteritis nodosa","volume":"33","author":"Lightfoot","year":"1990","journal-title":"Arthritis Rheum"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.2","doi-asserted-by":"crossref","first-page":"84","DOI":"10.1016\/j.jaut.2014.01.029","article-title":"Diagnosis and classification of polyarteritis nodosa","volume":"48\u201349","author":"Hern\u00e1ndez-Rodr\u00edguez","year":"2014","journal-title":"J Autoimmun"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.3","first-page":"386","article-title":"Acute pancreatitis with pseudocyst formation in a patient with polyarteritis nodosa","volume":"32","author":"Suresh","year":"2005","journal-title":"J Rheumatol"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.4","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0b013e318205a4c6"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.5","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780390720"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.6","doi-asserted-by":"publisher","DOI":"10.1002\/art.37715"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.7","first-page":"306","article-title":"High hepatitis B virus load in a patient with severe polyarthritis nodosa","volume":"10","author":"Ghorbani","year":"2010","journal-title":"Hep Mon"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.8","doi-asserted-by":"publisher","DOI":"10.1007\/s11926-005-0036-5"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.9","doi-asserted-by":"publisher","DOI":"10.1097\/01.meg.0000108362.41221.57"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.10","doi-asserted-by":"publisher","DOI":"10.1007\/s10067-003-0857-4"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.11","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/39.1.106"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.12","first-page":"77","article-title":"Drug-induced acute pancreatitis","volume":"21","author":"Kaurich","year":"2008","journal-title":"Proc (Bayl Univ Med Cent)"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.13","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2006.11.023"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.14","doi-asserted-by":"publisher","DOI":"10.1016\/j.bpg.2010.02.002"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.15","doi-asserted-by":"publisher","DOI":"10.1023\/B:DDAS.0000034562.17003.50"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.16","doi-asserted-by":"publisher","DOI":"10.1097\/00004836-200402000-00010"},{"key":"2025042702131729000_2016.jan05_1.bcr2015213495.17","doi-asserted-by":"publisher","DOI":"10.1111\/j.1744-9987.2009.00731.x"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2015-213495","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T09:13:28Z","timestamp":1745745208000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2015-213495"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,1,5]]},"references-count":17,"alternative-id":["10.1136\/bcr-2015-213495"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2015-213495","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2016,1,5]]}}}
