A Case of Adalimumab-associated Pancytopenia and Reversible Lymphadenopathy.

Adalimumab is a recombinant monoclonal antibody to tumor necrosis factor alpha (TNFα) used in the treatment of inflammatory and autoimmune conditions, including ulcerative colitis (UC). Adverse side effects include infection and injection-site cutaneous reactions; however, rare adverse events such as pancytopenia have been recorded. Here we describe a case of pancytopenia and reversible lymphadenopathy related to adalimumab administration in a patient with UC.
