The case of a 72-year-old male patient who presented to our centre for rare diseases with recurrent fever, night sweats and weight loss with initially confirmed mediastinal lymphadenopathy is reported. Investigation of lymph node material was unrevealing. As an additional finding, the patient had a myelodysplastic syndrome. VEXAS syndrome (vacuoles, E1 enzyme, X­linked, autoinflammatory, somatic) could be confirmed on the basis of a bone marrow biopsy and genetic testing.
