title: Four cases of acute leukemia with trisomy 4.
abstract: We report further on four cases of trisomy 4 in acute leukemia. Two cases were FAB type M4, one was type M1, and one was an undifferentiated leukemia. Two of our patients were children, aged 13 months and 11 years, respectively. In one case there was evidence of trisomy 4 occurring as a secondary change.
