title: [Angioimmunoblastic lymphadenopathy and colonic lymphoma].
abstract: Angioimmunoblastic lymphadenopathy (AILD), first discovered in the 70's, is an infrequent disease which generally proves fatal within a short time. It is characterized by lymphadenopathies, hepatosplenomegaly, fever and rash. The most frequent laboratory findings are: anemia, leukocytosis with lymphopenia and non specific hypergammaglobulinemia. In spite of being considered a non malignant disease, it produces important immunity disorders which predispose the patient to serious infections, frequently fatal. In the course of time patients are likely to develop malignant lymphomas or other types of tumors. We describe a ganglionar proliferation and general symptoms in a patient who had been diagnosed as AILD by ganglionar biopsy. She was treated with corticosteroids during 8 months after which she had a complete recovery. Three months later the patient was readmitted with enterrorhagias and clear deterioration of her general condition. Tests showed the existence of a colon tumor and absence of adenomegaly in the areas previously affected by AILD. A colon surgery was carried out and a specimen examined. The anatomopathologic examination confirmed the existence of an immunoblastic lymphoma infiltrating the regional ganglionar area. Colon lymphomas constitute only 4% of all colon tumors; they are related to chronic gastrointestinal disease such as Crohn disease, ulcerative colitis, malabsorption syndromes, tumors and others. We conclude that in this patient AILD and prednisone administration constituted favoring factors for the development of an extranodal lymphoma.
