PROTEINACEOUS LYMPHADENOPATHY IN A PATIENT WITH KNOWN RHEUMATOID-ARTHRITIS - CASE-REPORT AND REVIEW OF LITERATURE

We describe a case of proteinaceous lymphadenopathy (also called lymph node hyalinosis) in a 30-yr-old woman with known rheumatoid arthritis (RA). Amyloidosis was excluded by negative staining with congo red vi ewed with and without polarized light. Proteinaceous lymphadenopathy s hould be included in the differential diagnosis of patients with lymph adenopathy and long-standing RA. The histopathologist should be famili ar with the morphological appearances of this condition, which can be confused with amyloidosis. It appears that there is a good clinical re sponse in RA-associated proteinaceous lymphadenopathy following succes sful treatment of arthritis.
