[A unique case of destructive polyarthritis associated with multicentric Castleman's disease]

This is an original report of a 75-year-old woman suffering from multicentric Castleman's disease associated with a destructive polyarthritis, which do not correspond to any known rhumatologic disease. Cattleman's disease (angiofollicular lymph node hyperplasia) is a lymphoproliferative disorder of unknown etiology. Two forms are described: a localized and a multicentric. In the literature, associations of Cattleman's disease and connective tissue disease such as rheumatoid arthritis have been described. Association with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M component, skin changes) and amylosis have also been described.
