A rare autoinflammatory syndrome characterized by mostly early-onset, recurrent, refractory fever attacks, painful and recurrent mucosal ulceration affecting predominantly gastrointestinal (that may lead to inflammatory bowel disease), oral and genital areas. Additional variable features may include skin rash, psoriasis, axillary dermal abscesses, musculoskeletal disorders, polyarthritis, arthralgia, and autoimmune thyroid disorder. Ocular manifestations (including uveitis, chorioretinal scarring and macular fibrosis secondary to retinal vasculitis) are infrequent.
