Angioimmunoblastic lymphadenopathy of the colon with malignant transformation.

Angioimmunoblastic lymphadenopathy (AILD) is a rare disorder characterized by lymphadenopathy, constitutional symptoms, skin rashes, and a variety of hematologic disorders. Its occurrence in the colon is rare. Late in the disease, immunosuppression occurs, and there is an increased risk of malignant transformation. We present a case of AILD of the colon with eventual transformation into malignant lymphoma.
