VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic) syndrome is a rare and recently identified disease resulting from a somatic mutation in the X-linked UBA1 gene in cells of myeloid lineage. It can present in a myriad of ways with the potential to affect various organ systems, including the lungs. VEXAS is usually steroid responsive, but no strong data exists for the use of a steroid-sparing agent. There is limited emerging evidence for haematopoietic stem cell transplantation in a select number of cases. Regardless, prognosis for this condition is poor and a treatment algorithm remains a priority. Herein, we present a case of VEXAS that came to attention with discovery of a relatively asymptomatic interstitial lung disease and led to recurrent febrile episodes with evolving multi-organ involvement.
