title: [Seropositive polyarthritis as a presentation form of angioimmunoblastic lymphadenopathy].
abstract: We present a 59-year-old male who was admitted due to fever and generalized lymphadenopathy. The patient had polyclonal hypergammaglobulinemia, Coombs-positive anemia, positive rheumatoid factor (latex 1:1280-SCAT 1:128), hypocomplementemia, negative LE cells and FAN negative. He had a 2 months history of a rheumatoid arthritis-like polyarthritis with poor response to non-steroid antiinflammatory drugs. On physical examination a mild symmetrical polyarthritis of small and large joints was seen. A lymph node biopsy showed architectural effacement, absence of germinal centers, arborization of postcapillary venules and a polymorphonuclear infiltrate that included immunoblasts. Thus, this patient fulfills the morphologic criteria of angioimmunoblastic lymphadenopathy (AILD) (Fig. 1 and 2). Our purpose was to describe the association of seropositive polyarthritis with AILD as a presentation sign. Whether this represents a case of a rheumatoid arthritis with AILD or the polyarthritis which has been described as part of the clinical picture or AILD is difficult to say due to the short time evolution of the disease.
