title: Jejunal lymphoma in a patient with primary adult-onset hypogammaglobulinemia and nodular lymphoid hyperplasia of the small intestine.
abstract: A patient is presented with primary adult-onset hypogammaglobulinemia and nodular lymphoid hyperplasia of the small intestine complicated by a jejunal lymphoma. The tumor was resected and was classified as a malignant diffuse histiocytic lymphoma with involvement of mesenteric lymph nodes. Gastroenterological, immunological, histological, and immunopathological studies on this case are reported. The possibility that nodular lymphoid hyperplasia of the small intestine in hypogammaglobulinemia is a premalignant condition is discussed.
