title: [Rheumatoid polyarthritis with Gougerot-Sjögren's syndrome, pulmonary pseudolymphoma and digestive lymphoma. Apropos of a case].
abstract: The authors report a case of the Gougerot-Sjögren syndrome with rheumatoid arthritis, of particular interest because of lymphocytic proliferation. This was initially confined to the broncho-pulmonary tissues with histological appearances of pseudo-lymphoma, a diagnosis supported by clinical regression with immunosuppressive drugs, over a 5 years period. This difficult diagnosis needs histological, biochemical and clinical confirmation and, the very existence of this entity is debatable. The occurrence of a malignant lymphoma of the small intestine in the same patient a few years later is an argument in favour of the hypothesis that the pseudo-lymphoma was an intermediary pre-malignant stage of B-lymphocytic proliferation.
