Tuberculous peritonitis in a patient with rheumatoid arthritis treated with adalimumab.

We present a case of tuberculous peritonitis in a 71-year-old woman with long-standing rheumatoid arthritis treated with adalimumab, and we review the association between antitumor necrosis factor therapy and tuberculosis. Our case illustrates that the index of suspicion of tuberculosis in these patients, even with atypical clinical features, must be very high, and underscores the need of tuberculosis screening before therapy is started.
