Extensive multiple organ involvement in VEXAS syndrome.

A 55-year-old Japanese man was diagnosed with VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome, which is a newly documented adult-onset autoinflammatory disease caused by somatic UBA1 mutations [1], after four years of symptoms. He had suffered from recurrent fever after the onset of systemic arthralgia, scleritis, periorbital/orbital inflammation, optic perineuritis (A, B, T1-weighted contrast-enhanced magnetic resonance imaging in C and D, arrow in D), and myelodysplastic syndrome.
