Regular abdominal pain and fever in each menstruation onset: an unusual menses-associated familial Mediterrenean fever attacks and a favor result on colchicine treatment.

We present a 38-year-old woman suffering from regular abdominal pain and fever only in each menstruation onset for 7 years. The clinical symptoms, along with inflammatory findings during painful attacks, the beneficial effect of colchicine and genetic mutation (M694 V and M680I) supported the diagnosis of familial Mediterranean fever (FMF). A literature review indicated that FMF attacks occurring only during menstruation are rarely seen. This clinical picture may be confused with gynecological disorders especially in the people of Mediterranean origin.
