This review aims to make clinicians aware of the newly described syndrome, VEXAS. VEXAS should become an obvious differential diagnosis in cases of unexplained inflammation, anemia, and rheumatological and/or hematological manifestations. Patients with VEXAS are typically male aged > 60, with inflammation, and macrocytic anaemia. On suspicion of cancer or infections patients have frequently been exposed to extensive diagnostic procedures and hospital admissions. In this review, we summarise the current knowledge of VEXAS regarding pathogenesis, symptoms, diagnosis, and treatment.
