39 bone marrow eosinophilia cases which showed more than 10% of eosinophils in
marrow differential counts were analyzed according to etiology.
Mean valuers of eosinophils in differential count of these cases were 17.5±9.5% in
bone marrow and 23.7±16.4% in peripheral blood. Mean of absolute eosinophil counts of
peripheral blood was 5,788/cmm.
Other hematologic values were not so significant except moderate anemia (mean Hb
value, 10.7gm/dl) and leucocytosis (18,700/cmm) .
Clinical diagnosis and bone marrow findings were parasitic infestations in 12 cases
(31%), lymphoma in 4 cases(10%), other blood dyscrasias in 6 crises(15%), eosinophilia
associated with liver discases in 4 cases(10%), dermatologic diseases in 2 cases(5%),
allergic conditions in 2 cases(5%), malignant diseases in 3 cases(8%), undetermined
etiology in 2 eases(5%), varicose vein in 1 case, Raynaud disease in 1 case, dwarfism in
1 case and cryptococcosis in 1 case.
Degrees of eosinophilia in marrow differential count were 10∼19% in 26 cases, 20∼
29% in 8 cases, 30∼39% in 3 cases, and more than 40% in 2 cases, while absolute
eosinophil counts in peripheral blood were less than 500/cmm in 3 cases, 500∼2000/cmm
in 11 cases, 2000∼5000/cmm in 7 cases, 5000∼10000/cmm in 6 cases and more than
10000/cmm in 6 cases.
In cases of parasitic infestations, there were clonorchiasis in 3 cases, ascariasis in 3
cases, hook worm disease in 3 cases, trichocephaliasis in 2 cases and combined
infestation of hook worm, trichuris trichura, clonorchis sinensis and paragonimus
westermani in 1 case.
In cases of blood dyscrasias, there were malignant lymphoma in 4 cases.
In comparison with our previous report, cases of portal hypertension are decreased,
while parasitic infestations and 1ymphoma cases are markedly increased.
