Abstract
Chronic granulocytic leukemia (CGL) was diagnosed in the second trimester of pregnancy in a mother of four, who decided to terminate the pregnancy immediately. According to the literature this unusual combination is not a definite indication for abortion since CGL does not adversely affect the course of the pregnancy nor the pregnancy alter the course of the disease. Prudent treatment with busulfan or splenic irradiation, when indicated, apparently does not endanger the development of the fetus.
