Hashimoto's Thyroiditis in a Child with Familial Mediterranean Fever: a Case Report

Familial Mediterranean Fever (FMF) is an auto inflammatory disease[1] and also it can occur together with autoimmune disorders, such as Behçet's syndrome and systemic Lupus erythematosus[2,3]. Here, we present Familial Mediterranean fever and Hashimoto’s thyroiditis association in a 10-year-old girl. This girl was admitted to our hospital with a history of intermittent abdominal pain, fever, headache and chest pain. Her complaints have been recurring two or three times every month lasting 4-5 days for approximately two years. On admission, the physical findings were remarkable for fever and general abdominal tenderness. Laboratory studies revealed elevated levels of C-reactive protein and fibrinogen. Urinalysis and stool were normal. Abdominal ultrasonography and direct abdominal X-rays were unremarkable. So, she was diagnosed as FMF with periodic fever, abdominal and chest pain[4]. Her complaints resolved with colchicine treatment.
