However, it is rare for a DLBCL to present as a clinically subcutaneous mass without visible skin changes or nodal involvement. A 36-year-old man presented with a 4\u00d74\u00d71\u2009cm subcutaneous mass to his shoulder with normal overlying skin which had been enlarging over 6\u2009months. Physical exam and imaging together made a strong case for sarcoma, and the patient underwent a radical resection. The final pathological diagnosis returned as a diffuse B-cell lymphoma (germinal centre type). The patient subsequently healed and tolerated chemotherapy well. DLBCL can masquerade as a soft tissue mass at initial presentation. If the diagnosis is not clear, a biopsy should be pursued.<\/jats:p>","DOI":"10.1136\/bcr-2019-229327","type":"journal-article","created":{"date-parts":[[2019,7,27]],"date-time":"2019-07-27T11:45:48Z","timestamp":1564227948000},"page":"e229327","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Subcutaneous mass concerning for sarcoma: a peculiar presentation of diffuse large B-cell lymphoma"],"prefix":"10.1136","volume":"12","author":[{"given":"John","family":"Mayo","sequence":"first","affiliation":[{"name":"General Surgery, Tripler Army Medical Center, Honolulu, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth","family":"Bogenberger","sequence":"additional","affiliation":[{"name":"General Surgery, Tripler Army Medical Center, Honolulu, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Raj","sequence":"additional","affiliation":[{"name":"General Surgery, Tripler Army Medical Center, Honolulu, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey","family":"Reha","sequence":"additional","affiliation":[{"name":"General Surgery, Tripler Army Medical Center, Honolulu, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,7,27]]},"reference":[{"key":"2025082802360860000_12.7.e229327.1","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.2015.94"},{"key":"2025082802360860000_12.7.e229327.2","doi-asserted-by":"publisher","DOI":"10.1038\/35000501"},{"key":"2025082802360860000_12.7.e229327.3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa012914"},{"key":"2025082802360860000_12.7.e229327.4","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2141.2003.04749.x"},{"key":"2025082802360860000_12.7.e229327.5","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200312000-00006"},{"key":"2025082802360860000_12.7.e229327.6","doi-asserted-by":"crossref","first-page":"e153","DOI":"10.1097\/RLU.0b013e31821c9a7d","article-title":"Bilateral cutaneous diffuse large B-cell lymphoma on FDG PET\/CT","volume":"36","author":"Kalender","year":"2011","journal-title":"Clin Nucl Med"},{"key":"2025082802360860000_12.7.e229327.7","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1097\/RLU.0000000000002221","article-title":"Multiple subcutaneous nodules as initial presentation of diffuse large B-cell non-hodgkin lymphoma (DLBCL) detected by PET\/CT","volume":"43","author":"Shen","year":"2018","journal-title":"Clin Nucl Med"},{"key":"2025082802360860000_12.7.e229327.8","doi-asserted-by":"crossref","first-page":"757","DOI":"10.2217\/fon.12.40","article-title":"Subcutaneous diffuse large B-cell lymphoma with intraocular involvement","volume":"8","author":"Chi","year":"2012","journal-title":"Future Oncol"},{"key":"2025082802360860000_12.7.e229327.9","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdv304"},{"key":"2025082802360860000_12.7.e229327.10","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2005.09.137"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-229327","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T09:36:15Z","timestamp":1756373775000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-229327"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7]]},"references-count":10,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2019,7,27]]},"published-print":{"date-parts":[[2019,7]]}},"alternative-id":["10.1136\/bcr-2019-229327"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-229327","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2019,7]]}}}
