Abstract
Morphologic, immunologic, cytogenetic, and clinical features were studied in 9 cases of acute undifferentiated leukemia (AUL). These patients were unclassifiable by FAB criteria, they were CD34+ and did not express myeloid- or lymphoid-associated antigens (CD13, CD33, CD14, CD15, CD61, CD19, CD10, CD22, CD7, CD2, CD5, CD3). Clonal abnormalities were seen in 8 of 9 cases. Del(5q) as the sole anomaly was observed in 3 cases; +13 was the primary change in 3 cases, and isolated trisomy 12 was found in 1 patient. A complex karyotype with trisomy 12q, in association with del 17p and trisomy 21q was detected in 1 case. One patient with 5q- relapsed with refractory anemia with excess of blasts; the presence of dysgranulopoiesis and a few blasts with possible monocytoid morphology in the remaining 2 patients point to a "myeloid nature" of these leukemias. Analysis of cytologic features in our 3 patients with +13, in combination with previously reported cases, suggests the occurrence of immature stem cell involvement with limited differentiation potential, possibly more along the myeloid than the lymphoid lineage. The significance of trisomy 12q in this subset of leukemia remains elusive; some clues of minimal differentiation towards the...Continue Reading
