Single-organ polyarteritis nodosa
Definition
Single-organ polyarteritis nodosa (PAN) is a rare, often mild form of PAN characterized by limited disease without generalized manifestations, most often affecting the skin (cutaneous PAN), the brain, eyes, pancreas, testicles, ureter, breasts, or ovaries. Affected patients are often younger than those with systemic PAN and relapses appear to be more common.
