[Case Report Comment] Tuberculosis and Poncet’s disease: the many faces of an old enemy

In The Lancet, Arora and colleagues1 describe a patient with constitutional symptoms, bilateral pulmonary infiltrates, cervical lymphadenopathy, skin nodules, and symmetrical large joint polyarthritis. The multisystem involvement suggests an underlying cause such as tuberculosis, sarcoidosis, vasculitis, HIV, or possibly multiple origins. Lymph node and skin biopsy samples were pathognomonic of tuberculosis. No information about tuberculosis culture is provided and it is assumed that drug susceptibility testing was not done.
