Familial Mediterranean Fever Mimicking Metastatic Crohn's Disease.

ABSTRACT

Familial Mediterranean fever (FMF) is a hereditary disorder that presents with recurrent fever, rash, and polyserosal inflammation. The nonspecific symptoms of FMF allow it to mimic a large variety of diseases including metastatic Crohn's disease (MCD). MCD is a rare extraintestinal manifestation of Crohn's disease characterized by the presence of cutaneous noncaseating granulomas that are noncontiguous within the gastrointestinal tract. We describe a patient who had a delay in diagnosis of FMF as her clinical presentation mimicked MCD.
