This article considers the case of a 58-year-old man who presented with a 35-year history of Crohn's disease, pararectal fistulas and abscess formation. He had been taking azathioprine therapy for approximately 5.5 years. He was started on infliximab; however, his fistulas persisted and the abscess recurred. He was, therefore, switched to adalimumab. After development of pancytopenia, a bone marrow biopsy and a diagnostic splenectomy were performed, leading to a diagnosis of hepatosplenic T-cell lymphoma.
