To the Editor: We read with great interest Drini and colleagues’ recent report of hepatosplenic T-cell lymphoma (HSTCL) associated with inflammatory bowel disease. The occurrence of this rare lymphoma is partly driving a move away from the use of combination thiopurine and anti-tumour necrosis factor alpha therapy. It is important to recognise that risk of HSTCL is not only associated with exposure to thiopurine drugs with or without infliximab. It is associated with immunocompromise in general, and also occurs de novo. Explaining relative risks to patients is never easy and needs to be balanced with the need for treatment in properly selected patients.
