[Adult onset Still's disease and lymphoma: a rare association].

Adult onset Still's disease (AOSD) and lymphomas are diseases characterized by very similar clinical and histopathological manifestations. The association between these diseases has rarely been reported in the literature. We here report the case of a 26-year old patient diagnosed with adult onset Still's disease.

[Ruptured renal artery aneurysms in microscopic polyangiitis].

Introduction: Renal artery aneurysms are unusual manifestations of microscopic polyangiitis.

Observation: We report the case of a 55 years old male patient, with a microscopic polyangiitis, which was revealed by a demyelinating polyradiculoneuropathy, the diagnosis was made with association of alveolar hemorrhage, peripheral neuropathy and glomerulonephritis with positive antineutrophil cytoplasmic antibodies (antimyeloperoxidase antibodies). The evolution was marked by a state of shock by rupture of aneurysms of intrarenal arteries.
