Examination revealed she had a swelling of the first and the second metatarsophalangeal joints. Magnetic resonance imaging revealed abnormal soft tissue thickening between the second and the third metatarsal and a single large encapsulating indeterminate soft tissue mass with a peripheral inflammatory rim. The appearance was suggestive of a malignant sarcoma rather than a rheumatoid nodule or rheumatoid tenosynovitis. The patient was referred to the regional sarcoma unit where the scans were reviewed, and a sarcoma was ruled out. The patient then underwent excision of the indeterminate soft tissue mass. Histology revealed granulomatous infiltration suggestive of a rheumatoid nodule. This has not been described previously in the literature.<\/jats:p>","DOI":"10.1093\/jscr\/rjad278","type":"journal-article","created":{"date-parts":[[2023,5,27]],"date-time":"2023-05-27T23:23:08Z","timestamp":1685229788000},"source":"Crossref","is-referenced-by-count":0,"title":["Rheumatoid nodule presenting as an indeterminate soft tissue mass in the sole of the foot"],"prefix":"10.1093","volume":"2023","author":[{"given":"Ravi","family":"Patel","sequence":"first","affiliation":[{"name":"Department of Trauma and Orthopaedics, The Princess Royal Hospital , Telford , UK"},{"name":"Department of Trauma and Orthopaedics, Robert Jones and Agnes Hunt Orthopaedic Hospital , Oswestry , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raghav","family":"Nand","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedics, Scunthorpe General Hospital , Scunthorpe , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dakshinamurthy","family":"Sunderamoorthy","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedics, Scunthorpe General Hospital , Scunthorpe , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,5,27]]},"reference":[{"key":"2023052723225804700_ref1","doi-asserted-by":"crossref","first-page":"1103","DOI":"10.3899\/jrheum.201290","article-title":"Perforating rheumatoid nodule mimicking malignant soft-tissue mass of the forearm","volume":"48","author":"Ornetti","year":"2021","journal-title":"J Rheumatol"},{"key":"2023052723225804700_ref2","doi-asserted-by":"crossref","first-page":"457","DOI":"10.1007\/s002560050418","article-title":"Rheumatoid nodule of the foot: MRI appearances mimicking an indeterminate soft tissue mass","volume":"27","author":"Sanders","year":"1998","journal-title":"Skeletal Radiol"},{"key":"2023052723225804700_ref3","doi-asserted-by":"crossref","first-page":"111","DOI":"10.1046\/j.1460-9584.2002.00289.x","article-title":"Rheumatoid nodule as a cause of Morton\u2019s metatarsalgia","volume":"8","author":"Mcclelland","year":"2002","journal-title":"Foot Ankle Surg"},{"volume-title":"Rheumatoid arthritis and the seronegative spondyloarthropathies","year":"1988","author":"Resnick","key":"2023052723225804700_ref4"},{"key":"2023052723225804700_ref5","doi-asserted-by":"crossref","first-page":"216","DOI":"10.1016\/S0899-7071(97)00116-2","article-title":"Rheumatoid nodules: MRI characteristics","volume":"22","author":"Starok","year":"1998","journal-title":"Clin Imaging"},{"key":"2023052723225804700_ref6","doi-asserted-by":"crossref","first-page":"796","DOI":"10.1097\/00004728-199709000-00027","article-title":"Rheumatoid nodules: MR\/pathological correlation","volume":"21","author":"El-Noueam","year":"1997","journal-title":"J Comput Assist Tomogr"},{"key":"2023052723225804700_ref7","doi-asserted-by":"crossref","first-page":"625","DOI":"10.1136\/ard.52.9.625","article-title":"Rheumatoid nodules: differential diagnosis and immunohistological findings","volume":"52","author":"Veys","year":"1993","journal-title":"Ann Rheum Dis"},{"key":"2023052723225804700_ref8","first-page":"790","article-title":"Extraarticular manifestations during methotrexate therapy for rheumatoid arthritis","volume":"22","author":"Combe","year":"1995","journal-title":"J Rheumatol"},{"key":"2023052723225804700_ref9","doi-asserted-by":"crossref","first-page":"688","DOI":"10.1136\/ard.51.5.688","article-title":"An infiltrating rheumatoid nodule?","volume":"51","author":"Isdale","year":"1992","journal-title":"Ann Rheum Dis"}],"container-title":["Journal of Surgical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2023\/5\/rjad278\/50463587\/rjad278.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2023\/5\/rjad278\/50463587\/rjad278.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,5,27]],"date-time":"2023-05-27T23:23:18Z","timestamp":1685229798000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jscr\/article\/doi\/10.1093\/jscr\/rjad278\/7181244"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,5,1]]},"references-count":9,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2023,5,1]]}},"URL":"https:\/\/doi.org\/10.1093\/jscr\/rjad278","relation":{},"ISSN":["2042-8812"],"issn-type":[{"type":"electronic","value":"2042-8812"}],"subject":[],"published-other":{"date-parts":[[2023,5]]},"published":{"date-parts":[[2023,5,1]]},"article-number":"rjad278"}}
