Tick-borne relapsing fever with cutaneous eschar and radiculopathy, Ethiopia.

We report the first confirmed case of tick-borne borreliosis by molecular tools in a French traveler returning from Ethiopia with unusual presentation: the presence of cutaneous eschar after a hard tick-bite suggesting firstly to clinicians a diagnosis of tick-borne rickettsiosis.

Sarcoidosis: an unusual cause of acute pericarditis.

Mild to moderate asymptomatic pericardial effusions are commonly detected in patients with biopsy-proven sarcoidosis. However, symptomatic pericarditis is rare during the course of the disease. All reported cases at presentation were life-threatening tamponades.
