Familial Mediterranean fever (FMF) is an autoinflammatory disorder characterized by recurrent febrile polyserositis and arthritis. Although accompanying seronegative spondyloarthropathy has been reported in FMF, coexistence with rheumatoid arthritis (RA) is very rare. This case report describes a Japanese female RA patient who presented with periodic fever. Genetic analysis revealed compound he...

Introduction Familial Mediterranean fever (FMF) is an autosomal recessive auto-inflammatory disease, presenting with recurrent episodes of fever and polyserositis. Diagnosis of FMF is may be challenging especially in pediatric population. Mitochondrial fatty acid oxidation disorders and porphyrias can present with periodic abdominal and muscle pain. Incidence of both FMF and inherited metabolic...

Familial Mediterranean fever (FMF) is an autoinflammatory disorder characterized by recurrent febrile polyserositis and arthritis attacks. Accompanying seronegative spondyloarthropathy has been reported in FMF in addition to its own joint involvement. However, the coexistence of FMF with juvenile idiopathic arthritis (JIA) is very rare, only three cases with severe joint involvement and mortal ...

Objectives FMF is the most common autoinflammatory disease characterized by recurrent febrile polyserositis. The gravest consequence of FMF is nephropatic amyloidosis of AA type, which may progress to affect other organs, including the lungs[]. Pulmonary hypertension (PH) in FMF related amyloidosis is rare; only a few cases have been reported so far[,]. We aim to elucidate development of PH in ...

We describe a case of a 40-year-old woman who was admitted to the intensive care unit with a rapid onset of dyspnea and orthopnea. She presented progressive weakness, weight loss and secondary amenorrhea during last year, while intermittent fever was present for the last two months. Initial biochemical evaluation showed anemia, hyponatremia and increased C-reactive protein levels. Clinical and ...

Mucinous cystadenoma is a rare benign neoplasm and is usually discovered incidentally. Pleuritis and pericarditis, inflammation of the pleura and pericardium, may represent manifestations of autoimmune disorders especially in female subjects. We report a patient with polyserositis that was resolved after removal of the mucinous cystadenoma. To the best of our knowledge, this is a first report d...
