Most cases of primary TB present as pulmonary TB; however, between 10% and 20% include extrapulmonary manifestations. Almost 26% of extrapulmonary manifestations include musculoskeletal TB. The risk of reactivation of latent TB is approximately 10% per year and is most common in those with immunocompromising conditions. Diagnosis of extrapulmonary TB remains elusive because of atypical presentation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case<\/jats:title>\n                    <jats:p>\n                      We present a case of a 71\u2010year\u2010old man with a history of renal transplantation and previously treated latent TB who presented with worsening left lower extremity pain and swelling over the previous six months. Initially, the patient was unsuccessfully treated for presumed bacterial cellulitis with several rounds of antibiotics. The patient was then seen by Dermatology, who diagnosed presumed primary erythema nodosum. He was managed with prednisone and topical steroids for several months with only partial improvement. At admission, physical exam was significant for a 4\u2009\u00d7\u20093\u2010cm erythematous, warm, and tender area on the lower left extremity. Labs showed elevated neutrophils and lymphopenia, and an MRI of the limb suggested hindfoot abscesses, talonavicular septic arthritis, and surrounding osteomyelitis. Intraoperative cultures grew acid\u2010fast bacilli and were confirmed to be pan\u2010sensitive\n                      <jats:italic>M. tuberculosis<\/jats:italic>\n                      complex.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Musculoskeletal TB diagnosis requires a high index of suspicion, thorough physical exam, imaging, and tissue for culture and biopsy. Special attention should be placed on the combined risk factors of previous TB diagnosis, immunocompromised status, and symptoms refractory to alternative management strategies such as antibiotics and corticosteroids.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/crdi\/5905265","type":"journal-article","created":{"date-parts":[[2025,10,25]],"date-time":"2025-10-25T09:39:58Z","timestamp":1761385198000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Wolf in Sheep\u2019s Clothing: Extensive Musculoskeletal and Cutaneous TB Masquerading as Primary Erythema Nodosum"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-9282-4874","authenticated-orcid":false,"given":"Tanner","family":"Shull","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3517-1398","authenticated-orcid":false,"given":"Hemil","family":"Gonzalez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,10,25]]},"reference":[{"key":"e_1_2_11_1_2","unstructured":"World Health Organization Global Tuberculosis Report 2024 2024 https:\/\/www.who.int\/publications\/i\/item\/9789240101531."},{"key":"e_1_2_11_2_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pmed.1002152"},{"key":"e_1_2_11_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a121593"},{"key":"e_1_2_11_4_2","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwt246"},{"key":"e_1_2_11_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/152.3.247"},{"key":"e_1_2_11_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arcmed.2004.05.008"},{"key":"e_1_2_11_7_2","first-page":"620","article-title":"Risk Factors for Extra-Pulmonary Tuberculosis Compared to Pulmonary Tuberculosis","volume":"13","author":"Lin J.
