Four consistent markers, involving chromosomes 8, 11, 14, 18, 21 and 22, were found in the majority of meta‐phases obtained after stimulation of peripheral blood and bone marrow from a patient with a T‐cell chronic lym‐phocytic leukemia (CLL) and a concomitant IgA/lambda myeloma with phytohemagglutinin (PHA), lipopolysac‐charide of E. coli(LPS) and S. aureus strain Cowan I bacteria (Cowan). A second malignant clone with three additional markers was observed after stimulation with Con‐canavalin A (Con A). A chromosome 14 aberration, inv(14) (q11‐q32), may be of significance in the T‐cell malignancy and may suggest a common clonal origin of the two tumors.
