Case Reports
[Pseudo-myelomatous plasmacytosis of the bone marrow in a multicentric Castleman's disease].
The authors report the case of a 35 year-old polynesian male admitted to hospital with a diagnosis of myeloma. Bone marrow study showed an intense plasmocytosis, mature, Marshalko type. ⋯ Such massive, reactive plasmacytosis belong to one of the various pathological features of multicentric Castleman's disease. Thus, this disease should belong to the etiologic diagnosis of intense bone marrow plasmacytosis and be distinguished from multiple myeloma, sometimes associated to Castleman's disease, especially in case of POEMS syndrome.
