Core Tip

Core Tip: We report a case of idiopathic multicentric Castleman disease (iMCD) with pulmonary parenchyma and skin involvement as the primary clinical manifestations. The patient had presented to several tertiary hospitals for more than 3 years before he was finally diagnosed. iMCD is a rare systemic lymphoproliferative disease, and delays in diagnosis are common and remain a concern. Clinicians need to improve their understanding of iMCD. Combination therapy with anti-interleukin 6 (IL-6) monoclonal antibodies and glucocorticoids is an effective frontline treatment regimen, especially for those with an elevated level of serological IL-6.
