Sarcoidosis is a multisystemic granulomatous disease of unknown cause occurring in young adults. Cardiac sarcoidosis patients are at increased risk for atrioventricular blocks and ventricular arrhythmias. Sinus node dysfunction is scarcely reported. ⋯ Sinus node dysfunction may be the first manifestation of cardiac sarcoidosis. In unexplained sinus node dysfunction in young patients, advanced cardiac imaging is a key to cardiac sarcoidosis diagnostic. Early recognition of cardiac sarcoidosis enables to start immunosuppressive treatment and discuss implantable cardioverter defibrillator implantation.

Review Case Reports
[ANCA vasculitis preceded by isolated joint manifestations. Report of two cases and literature review].
Joint manifestations of ANCA (antineutrophil cytoplasmic antibody) associated vasculitis (AAV) are extremely common in the progression of systemic damages. However, the joint involvement is rarely isolated. The diagnosis and the treatment are difficult in this particular situation and few data are available on the topic. ⋯ Isolated joint manifestations of ANCA vasculitis are rare but can lead to a delay in diagnosis. ANCA vasculitis should be considered in seronegative symmetrical polyarthritis by looking for ANCA in a second line biological test. Methotrexate is the first treatment option to be considered. In case of insufficient response or failure, rituximab seems an interesting option in this context.
