Familial Mediterranean Fever Present with Gastrointestinal Manifestations of Henoch Schonlein Purpura

Henoch Schönlein Purpura is the most common small vessel vasculitis in childhood which is characterized with non-thrombocytopenic purpuric skin rash, arthritis, abdominal pain and renal disease. Palpable purpura usually occurs as the first clinical finding. However, gastrointestinal symptoms can rarely appear before the rash and may cause delays in diagnosis. Here, we present a case of Henoch Schönlein Purpura who underwent appendectomy with the diagnosis of acute abdomen and developed skin involvement in clinical follow-up. Another important point of our case is; In the genetic analysis performed in our patient with Henoch Schönlein purpura attack, Familial Mediterranean Fever was diagnosed with heterozygous mutation M694V and V726A . Since Henoch Schönlein Purpura is more common in Familial Mediterranean Fever patients; Familial Mediterranean Fever findings should be questioned in patients with Henoch Schönlein Purpura and gene mutation analysis should be performed if Familial Mediterranean Fever findings are specified.
