Abstract
Case reports of Jordans' anomaly are uncommon. A 22-year-old male student had been treated for congestive cardiomyopathy since January 1975. On February 20, 1979, peripheral blood smears stained with May-Grünwald-Giemsa revealed granulocytes and monocytes containing 1∼3μ in diameter of vacuoles in their cytoplasma. In the bone marrow blood smears few vacuoles were observed in the promyelocytes. The count of vacuoles gradually increased in number with maturation of granulocytes, and reached up to 14 in segmented neutrophils. The vacuoles were found in plasma cells, but not in the lymphocytes, erythrocytes or megakaryocytes. These vacuoles were negative for PAS staining but were stained deep red with Demel' staining. These cytoplasmic vacuoles were also found in the myocardium, but not in the left femoral muscle.
There are only three reports of Jordans' anomaly including the present case in Japan.
