We report a patient who was operated on for a progressively enlarging soft tissue lump at the base of his thumb. Initially, it was thought to be a post-traumatic false aneurysm arising from a branch of the radial artery following blunt trauma. Subsequent histology revealed it to be a Masson tumour. We aim to highlight this rare pathology that can affect the hand and the diagnostic confusion we faced during the evaluation and management of this patient. <\/jats:p><jats:p> Level of Evidence: Level V (Therapeutic) <\/jats:p>","DOI":"10.1142\/s2424835525720099","type":"journal-article","created":{"date-parts":[[2025,8,22]],"date-time":"2025-08-22T08:19:40Z","timestamp":1755850780000},"source":"Crossref","is-referenced-by-count":0,"title":["Masson Tumour \u2013 A Rare Cause of a Hand Lump"],"prefix":"10.1142","author":[{"given":"Thilina","family":"GUNAWARDENA","sequence":"first","affiliation":[{"name":"Teaching Hospital, Polonnaruwa, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Waruni","family":"DISSANAYAKA","sequence":"additional","affiliation":[{"name":"Teaching Hospital, Polonnaruwa, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2025,8,22]]},"container-title":["The Journal of Hand Surgery (Asian-Pacific Volume)"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S2424835525720099","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,22]],"date-time":"2025-08-22T08:19:40Z","timestamp":1755850780000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/10.1142\/S2424835525720099"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,22]]},"references-count":0,"alternative-id":["10.1142\/S2424835525720099"],"URL":"https:\/\/doi.org\/10.1142\/s2424835525720099","relation":{},"ISSN":["2424-8355","2424-8363"],"issn-type":[{"value":"2424-8355","type":"print"},{"value":"2424-8363","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,22]]},"article-number":"S2424835525720099"}}
