Concomitant disseminated histoplasmosis and disseminated tuberculosis after tumor necrosis factor inhibitor treatment: a case report.

Background: Tumor necrosis factor antagonist inhibitors have transformed the approach to patients with severe autoimmune conditions, such as rheumatoid arthritis. Although the therapy can be highly effective, TNF-α inhibitors are associated with an increased risk of opportunistic infections.

Case Presentation: Here, we report a case of concomitant disseminated histoplasmosis and tuberculosis in a 65-year-old female with rheumatoid arthritis treated with TNF-α inhibitor.
