Management is presently limited to supportive care, acid suppression and endoscopic treatment. Many cases of gastric antral vascular ectasia tend to be refractory or partially responsive to standard treatment and require multiple endoscopic procedures to control the recurrent bleeding. Immunosuppression is not part of the recommended management of gastric antral vascular ectasia: limited data exist on the role of cyclophosphamide or autologous stem cell transplant in severe cases, but no prospective data or randomised controlled trial supports its routine use. Here, we present a case of an adult male patient with diffuse cutaneous systemic sclerosis complicated by arthritis and severe gastric antral vascular ectasia. The latter required multiple endoscopic procedures and remained transfusion-dependent. Due to progressive skin disease and active arthritis refractory to conventional synthetic disease-modifying antirheumatic drugs, the patient was started on tocilizumab. While he showed an early response in terms of scores related to skin involvement and arthritis, response to gastric antral vascular ectasia was unexpected. As soon as the biologic therapy was started, the patient was no longer transfusion-dependent and haemoglobin levels started to rise. Subsequent endoscopic investigations confirmed resolution of gastric antral vascular ectasia. This case is illustrative of an unexpected response to tocilizumab, and this observation is supported by the biological rationale of interleukin-6 in vascular remodelling. N1 - © The Author(s) 2025.
