Due to resemblance with benign conditions it can often result in misdiagnosis. We report a case of Marjolin\u2019s SCC affecting the proximal hallux in a patient with recurrent ingrown toenail infections. A 58-year-old woman with a background of wedge resections for ingrown toenail and distal phalanx amputation for osteomyelitis presented with pain and hyperkeratotic raised ulcer around the proximal phalanx. MRI scan revealed soft tissue mass infiltrating the proximal phalanx with biopsies confirming a SCC. The patient underwent first ray amputation and made a good clinical recovery and remains disease free. Due to clinical similarities with benign conditions, awareness of Marjolin\u2019s SCC as a potential diagnosis when treating patients with recurrent ingrown toenail is imperative. We recommend patients with recurrent ingrown toenail or ulceration with a background of chronic infection have biopsies performed to exclude potential malignancy.<\/jats:p>","DOI":"10.1136\/bcr-2017-219715","type":"journal-article","created":{"date-parts":[[2017,6,15]],"date-time":"2017-06-15T02:10:26Z","timestamp":1497492626000},"page":"bcr-2017-219715","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Marjolin\u2019s squamous cell carcinoma of the hallux following recurrent ingrown toenail infections"],"prefix":"10.1136","volume":"2017","author":[{"given":"Wahid","family":"Abdul","sequence":"first","affiliation":[{"name":"Department of Trauma and Orthopaedics, University Hospital of Wales, Cardiff, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Barry James","family":"O'Neill","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedics, University Hospital of Wales, Cardiff, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony","family":"Perera","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedics, University Hospital of Wales, Cardiff, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,6,14]]},"reference":[{"key":"2025082802034144000_2017.jun13_5.bcr-2017-219715.1","doi-asserted-by":"crossref","first-page":"547","DOI":"10.7547\/87507315-85-10-547","article-title":"Squamous cell carcinoma of the nail bed","volume":"85","author":"Patel","year":"1995","journal-title":"J Am Podiatr Med Assoc"},{"key":"2025082802034144000_2017.jun13_5.bcr-2017-219715.2","doi-asserted-by":"crossref","first-page":"409","DOI":"10.7547\/87507315-84-8-409","article-title":"Squamous cell carcinoma.
