A 83-year-old man was diagnosed with primary myelofibrosis based on the presence of leukoerythroblastosis, splenomegaly, chromosome 46 XY, a dry tap bone marrow aspiration and fibrosis on bone marrow biopsy, when he was admitted for herpes zoster in June 1987. He was admitted for a second time with multiple subcutaneous tumors over his entire body in July, 1989. He had mild splenomegaly, but no hepatomegaly nor lymphadenopathy. Laboratory tests were as follows: RBC 214 x 10(4)/microliters, Hb 5.1 g/dl, Ht 17.7%, WBC 3,200/microliters with leukoerythroblastosis, platelets 11.6 x 10(4)/microliters, s-lysozyme 251 micrograms/ml, u-lysozyme 770 micrograms/ml, NAP ratio 98%, score 278. Bone marrow aspiration resulted in a dry tap. Bone marrow biopsy showed marked fibrosis. Histologic examination of subcutaneous tumor biopsy specimens revealed a diffuse infiltration of monocytes with flexuous nuclei. These cells were positive for alpha-naphtyl butyrate esterase stain, and negative for peroxidase, alpha-naphtol ASD chloroacetate esterase stain and platelet glycoprotein IIb/IIIa stain (APAAP). Ultrastructurally, these cells were mostly monocytes and promonocytes, while phenotypically, CD11b, CD13, CD14, CD33 and HLA-DR were positive. These date indicated that the subcutaneous tumors originated from monocytes.

A case of chronic myelogenous leukemia (CML) of 10-year survival in described. A 44-year old male was admitted to our hospital because of general malaise, abdominal fullness and fever in February, 1977. On physical examination, giant splenomegaly and hepatomegaly were detected. Peripheral blood examination revealed leukocytosis without hiatus leukemia , normochromic macrocytic anemia and thrombocytosis. NAP rate and score were 16% and 22. Cytogenetic analysis of PB without stimulator revealed 46, XY, Ph1. Then he was diagnosed as having a typical type of Ph1-positive CML. He had been successfully treated over 9 years by intermittent administration of busulfan. However, anemia suddenly progressed in February, 1986 followed by leukopenia and thrombocytopenia. Hemorrhage was not detected by the examination. Though he had been received blood transfusion, the anemia progressed rapidly. He was died of cachexia on 4th of August, 1987. The postmortem examination revealed bone marrow aplasia with no signs of blast crisis nor myelofibrosis. Secondary hemochromatosis was seen in the liver, spleen, pancreas and some other organs.

Of 43 elderly patients who were suspected to have polycythemia between October 1990 and July 1998, 12 patients showed an increased red cell volume measured by 51Cr-labeled red blood cells. We analyzed the clinical characteristics of the 12 patients consisted of 7 men and 5 women, with a median age of 71 (range: 57-92). Chief complaints were headaches and dizziness (3 cases), symptoms of other conditions than polycythemia (4 cases). Five patients had no symptoms. Five of 6 patients over 70 years old had no symptoms due to polycythemia. Seven cases (58%) showed splenomegaly and three cases (25%) showed hepatomegaly. Laboratory findings were as follows: WBC 9.7 +/- 3.9 x 10(3)/microliter (mean +/- SD, p < 0.02 vs normal control), Hb 17.9 +/- 4.2 g/dl (p < 0.001), Plt 39.7 +/- 26.0 x 10(4)/microliter, EPO 13.8 +/- 5.2 mU/ml (p < 0.0001), NAP score 258 +/- 114, Vit. B12 1,686 +/- 2,156 pg/ml, arterial O2 saturation more than 92% in all cases. The diagnosis of all cases was polycythemia vera according to the diagnostic criteria of Polycythemia Vera Study Group. Associated conditions included 8 cases of thrombosis (cerebral thrombosis 4, thrombophrebitis 2, myocardial infarction 1, ischemic colitis 1) and 3 cases of malignancy (esophageal cancer 1, breast cancer 1, renal cancer 1), none of which was therapy-related cancer. Six patients (50%) had only phlebotomy, three (25%) only chemotherapy, and three (25%) both phlebotomy and chemotherapy. Patients over 80 years old needed neither intensive nor continuous treatment. Only one patient died due to esophageal cancer at age 89.
