We report here on patient with SLE with severe thoracic pyomyositis presented with right upper arm swelling and fever. The patient fully recovered after a serial surgical debridement and antibiotic therapy. Pyomyositis, as well as deep vein thrombosis, should be considered during the differential diagnosis of patients with SLE experiencing fever and unilateral limb oedema. CT and identification of causal pathogens are crucial in the diagnosis of pyomyositis. Early effective antibiotic treatment as well as surgical intervention can together bring about a better outcome.<\/jats:p>","DOI":"10.1136\/bcr-2021-246484","type":"journal-article","created":{"date-parts":[[2022,3,8]],"date-time":"2022-03-08T11:43:42Z","timestamp":1646739822000},"page":"e246484","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Severe thoracic pyomyositis in a patient with systemic lupus erythematosus"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1334-741X","authenticated-orcid":false,"given":"Yu-Ning","family":"Kuo","sequence":"first","affiliation":[{"name":"Division of Allergy, Immunology and Rheumatology, Department of Internal Medicine, Taichung Veterans General Hospital, Taichung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chih-Sheng","family":"Lai","sequence":"additional","affiliation":[{"name":"Division of Plastic and Reconstructive Surgery, Department of Surgery, Taichung Veterans General Hospital, Taichung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8135-9554","authenticated-orcid":false,"given":"Yi-Hsing","family":"Chen","sequence":"additional","affiliation":[{"name":"Division of Allergy, Immunology and Rheumatology, Department of Internal Medicine, Taichung Veterans General Hospital, Taichung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lai","family":"Kuo-lung","sequence":"additional","affiliation":[{"name":"Division of Allergy, Immunology and Rheumatology, Department of Internal Medicine, Taichung Veterans General Hospital, Taichung, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,3,8]]},"reference":[{"key":"2025082803090806000_15.3.e246484.1","doi-asserted-by":"crossref","DOI":"10.1111\/bpa.12950","article-title":"Infective myositis","volume":"31","author":"Narayanappa","year":"2021","journal-title":"Brain Pathol"},{"key":"2025082803090806000_15.3.e246484.2","doi-asserted-by":"publisher","DOI":"10.1136\/pgmj.2003.009274"},{"key":"2025082803090806000_15.3.e246484.3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200504073521417"},{"key":"2025082803090806000_15.3.e246484.4","doi-asserted-by":"crossref","first-page":"660","DOI":"10.1111\/tmi.13395","article-title":"Tropical pyomyositis: an update","volume":"25","author":"Shittu","year":"2020","journal-title":"Trop Med Int Health"},{"key":"2025082803090806000_15.3.e246484.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.nic.2011.07.011"},{"key":"2025082803090806000_15.3.e246484.6","doi-asserted-by":"crossref","DOI":"10.1016\/j.jns.2020.116767","article-title":"Purulent infectious myositis (formerly tropical pyomyositis)","volume":"413","author":"Habeych","year":"2020","journal-title":"J Neurol Sci"},{"key":"2025082803090806000_15.3.e246484.7","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2016-214809"},{"key":"2025082803090806000_15.3.e246484.8","first-page":"410","article-title":"Gluteal abscess causing sciatica in a patient with systemic lupus erythematosus","volume":"70","author":"Shames","year":"1989","journal-title":"Arch Phys Med Rehabil"},{"key":"2025082803090806000_15.3.e246484.9","unstructured":"Yoshino YHS , Takeuchi A , Hashimoto T .
