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. She had been previously treated for large B-cell Non-Hodgkin lymphoma (LBCNHL) with chemotherapy and haemopoietic stem-cell autograft with complete remission. The association between AOSD and lymphoma is rare and in all cases AOSD has been diagnosed before lymphoma. The peculiarity of this study lies in the succession LBCNHL- AOSD and raises several hypotheses on the association between these two diseases. The association between non-autoimmune diseases and lymphoid hemopathies have been widely demonstrated, whether it is the progression of autoimmune diseases vs lymphoma or non-autoimmune disease manifestations occurring in patients with this disease. This study highlights the difficult distinction between these diseases.
