VEXAS Syndrome: A Case Presentation and Overview

The presentation discusses a 62-year-old male patient with a complex clinical history including hypertension, recent DVT, and an impressive purpuric rash, diagnosed with VEXAS syndrome—a severe hematoinflammatory condition. Initially presenting with episodic rashes and symptoms indicative of relapsing polychondritis, the patient experienced a sudden exacerbation characterized by extensive hemorrhagic bullae. Laboratory tests revealed macrocytic anemia, thrombocytopenia, and hemolytic indicators. Histopathological examination indicated features of both vasculitis and neutrophilic dermatosis, leading to the diagnosis of VEXAS which is linked to UBA1 gene mutations and is characterized by systemic inflammation and diverse hematologic abnormalities. The discussion underscores the syndrome's male predominance, association with skin manifestations, and a significant mortality rate. The diagnostic process includes specific genetic testing, with treatment typically involving steroids followed by IL-6 inhibitors like tocilizumab. The patient responded well to therapy and is being monitored for ongoing management and potential clinical studies, highlighting the evolving understanding of VEXAS syndrome.
