We report the case of an 85-year-old woman presenting with infectious dactylitis of the third finger of the right hand, in whom radiographs revealed distal osteolysis in several digits. After excluding infectious, inflammatory and metabolic causes, genetic testing confirmed a heterozygous NOTCH2 mutation consistent with HCS. This case highlights the importance of recognising the characteristic radiographic and clinical findings in the hand, since its presentation may mimic rheumatologic or infectious conditions. Awareness of this entity allows accurate diagnosis, avoidance of unnecessary surgical interventions and optimised functional and preventive management.<\/jats:p>\n                  <jats:p>Level of Evidence: Level V (Therapeutic)<\/jats:p>","DOI":"10.1142\/s2424835526720136","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T08:29:27Z","timestamp":1788424167000},"page":"543-547","source":"Crossref","is-referenced-by-count":0,"title":["Digital Acro-osteolysis Revealing Hajdu\u2013Cheney Syndrome in an Elderly Patient: A Case Report"],"prefix":"10.1142","volume":"31","author":[{"given":"Antonio","family":"GARC\u00cdA-JIM\u00c9NEZ","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery and Traumatology, SSIBE \u2013 Hospital de Palam\u00f3s, Palam\u00f3s, Girona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lluis","family":"POMEROL","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery and Traumatology, SSIBE \u2013 Hospital de Palam\u00f3s, Palam\u00f3s, Girona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eul\u00e0lia","family":"ARMENGOL","sequence":"additional","affiliation":[{"name":"Department of Rheumatology, SSIBE \u2013 Hospital de Palam\u00f3s, Palam\u00f3s, Girona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"S2424835526720136BIB001","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph17176174"},{"key":"S2424835526720136BIB002","doi-asserted-by":"publisher","DOI":"10.1007\/s11914-016-0311-6"},{"key":"S2424835526720136BIB003","doi-asserted-by":"publisher","DOI":"10.1016\/j.semerg.2024.102287"},{"key":"S2424835526720136BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejmg.2018.04.015"},{"key":"S2424835526720136BIB005","doi-asserted-by":"publisher","DOI":"10.1111\/scd.12878"},{"key":"S2424835526720136BIB006","doi-asserted-by":"publisher","DOI":"10.1186\/s13023-014-0200-y"},{"key":"S2424835526720136BIB007","doi-asserted-by":"publisher","DOI":"10.7860\/JCDR\/2016\/15782.7203"},{"issue":"4","key":"S2424835526720136BIB008","first-page":"574","volume":"20","author":"Blumenauer BT","year":"2002","journal-title":"Clin Exp Rheumatol"},{"key":"S2424835526720136BIB009","doi-asserted-by":"publisher","DOI":"10.3941\/jrcr.v8i9.1833"},{"key":"S2424835526720136BIB010","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2020.02.012"}],"container-title":["The Journal of Hand Surgery (Asian-Pacific Volume)"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S2424835526720136","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T08:21:09Z","timestamp":1791274869000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/10.1142\/S2424835526720136"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8,31]]},"references-count":10,"journal-issue":{"issue":"05","published-print":{"date-parts":[[2026,10]]}},"alternative-id":["10.1142\/S2424835526720136"],"URL":"https:\/\/doi.org\/10.1142\/s2424835526720136","relation":{},"ISSN":["2424-8355","2424-8363"],"issn-type":[{"value":"2424-8355","type":"print"},{"value":"2424-8363","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,8,31]]}}}
