A case of angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) with four cytogenetically different cell clones (49,XX,+5,+19,+21/47,XX,+X/46,XX,inv (14)(q11q32)/45,X,-X) is reported. To our knowledge, this is the first case of AILD with an inv(14)(q11q32), thus probably involving the T-cell receptor alpha-chain gene. The cytogenetic findings are discussed with respect to the possible progression of AILD to malignant lymphoma.
