Cryptogenic multifocal ulcerous stenosing enteritis (CMUSE), and neuromuscular and vascular hamartoma (NMVH): two sides of the same coin?

Multifocal stenosing enteritis, not related to Crohn's disease or drug intake, has been described under two different terms: "cryptogenic multifocal ulcerous stenosing enteritis" (CMUSE) and "neuromuscular and vascular hamartoma" (NMVH). We present three new cases of this condition and argue that the two terms reflect the same disease entity. Although etiology and pathogenesis of the disease remain largely unclear, obliterative vascular changes may play an important role. © Georg Thieme Verlag KG Stuttgart · New York.
