Newly Diagnosed Crohn's Disease in Patient with Familial Mediterranean Fever.

Chronic abdominal pain sometimes constitute a major challenge, specially when a patient has two diseases with dominant features of abdominal pain in both. At this point, clinicians face a daunting task both in diagnosing and treating an individual's chronic abdominal pain. Similarly, familial Mediterranean fever disease and Crohn's disease have the same clinical features in terms of chronic abdominal pain, and inflammatory properties of these diseases. The association of familial Mediterranean fever disease and Crohn's disease is very rare and may lead to a remarkable challenge in both diagnosis and treatment. Here, we report a young man with FMF disease presented with extraordinary and intolerable abdominal pain relieved only by excessive narcotic analgesics. The presented case was diagnosed with CD and successfully treated with anti-TNF (tumor necrosis factor) due to steroid refractory.
