He was initially treated with corticosteroids, first by local injection then systemically, but with no effect. When re-evaluated, the patient had developed a rash, and the symptoms had spread locally to surrounding structures. At this point, the patient added to the medical history that he had been stung by a sculpin a month before the debut of symptoms. Based on this, the patient\u2019s involved area was biopsied, and subsequent microbiology findings proved consistent with <jats:italic>Mycobacterium marinum<\/jats:italic> infection. By the time of diagnosis, the patient had soft tissue involvement, arthritis and osteomyelitis with an overlying rash. This case emphasises the need for reassessment when treatment is not effective and for further investigations of the medical history to establish the correct diagnosis and treatment.<\/jats:p>","DOI":"10.1136\/bcr-2020-234417","type":"journal-article","created":{"date-parts":[[2021,5,12]],"date-time":"2021-05-12T13:12:04Z","timestamp":1620825124000},"page":"e234417","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Rare case of <i>Mycobacterium marinum<\/i> in a patient presenting with tenosynovitis"],"prefix":"10.1136","volume":"14","author":[{"given":"Henrik Zachar","family":"Langkilde","sequence":"first","affiliation":[{"name":"Department of Medicine, Vejle Hospital, University Hospital of Southern Denmark, Vejle, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4525-3680","authenticated-orcid":false,"given":"Kim","family":"Nesten","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Hand Surgery, University Hospital of Southern Denmark, Vejle, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5083-663X","authenticated-orcid":false,"given":"Melanie Birger","family":"Morillon","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Odense University Hospital - Svendborg, Denmark, Svendborg, Denmark"},{"name":"Research Unit of Rheumatology, Department of Clinical Research, University of Southern Denmark, Odense University Hospital, Odense, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,5,12]]},"reference":[{"doi-asserted-by":"publisher","key":"2025082723420518000_14.5.e234417.1","DOI":"10.1001\/archinte.162.15.1746"},{"key":"2025082723420518000_14.5.e234417.2","doi-asserted-by":"crossref","first-page":"98","DOI":"10.1177\/230949901001800122","article-title":"Review article: Mycobacterium marinum infection of the hand and wrist","volume":"18","author":"Cheung","year":"2010","journal-title":"J Orthop Surg"},{"key":"2025082723420518000_14.5.e234417.3","doi-asserted-by":"crossref","first-page":"655","DOI":"10.1007\/s15010-015-0776-8","article-title":"Twenty-eight cases of Mycobacterium marinum infection: retrospective case series and literature review","volume":"43","author":"Johnson","year":"2015","journal-title":"Infection"},{"key":"2025082723420518000_14.5.e234417.4","doi-asserted-by":"crossref","first-page":"457","DOI":"10.1007\/s15010-013-0403-5","article-title":"Clinical and pathological characteristics of mycobacterial Tenosynovitis and arthritis","volume":"41","author":"Hsiao","year":"2013","journal-title":"Infection"},{"doi-asserted-by":"publisher","key":"2025082723420518000_14.5.e234417.5","DOI":"10.5435\/JAAOS-D-14-00216"},{"key":"2025082723420518000_14.5.e234417.6","doi-asserted-by":"crossref","first-page":"555","DOI":"10.1016\/j.pop.2018.05.010","article-title":"Approach to aquatic skin infections","volume":"45","author":"Vasagar","year":"2018","journal-title":"Prim Care"},{"key":"2025082723420518000_14.5.e234417.7","doi-asserted-by":"crossref","first-page":"214","DOI":"10.1177\/230949901202000216","article-title":"Mycobacterium marinum infection of the hand and wrist","volume":"20","author":"Cheung","year":"2012","journal-title":"J Orthop Surg"},{"doi-asserted-by":"crossref","unstructured":"Aubry A , Mougari F , Reibel F .
