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 48-year-old male was admitted to our hospital on April 20, 1989 because of general fatigue and abdominal fullness. Physical examination showed hepatomegaly, massive splenomegaly, and systemic lymphadenopathy. Hematological findings revealed WBC 73,000/microliters, RBC 289 x 10(4)/microliters, Hb 8.0g/dl, and platelet 9.1 x 10(4)/microliters. WBC differential count demonstrated a mixture of 63% matured small lymphocytes and 32% prolymphocytoid cells. Bone marrow aspiration was unsuccessful with a dry tap. Surface marker analysis of peripheral blood lymphoid cells disclosed that they were positive for anti-HLA-DR, CD 5, CD 19, CD 20, CD 21, CD 25, Sm-IgM, Sm-IgD, and Sm-K. He was diagnosed as B-CLL/PL, and treated with VEPA with partial remission. CLL/PL which was advocated by Melo in 1986 is regarded as a distinct clinical entity intermediate between CLL and PLL in clinical and laboratory features. Our case is interesting with regard to good response to combination chemotherapy, though most cases of CLL/PL have a resistance to standard chemotherapy.

Hairy cell leukemia (HCL) has been mainly reported from the Western countries. Herein we describe a case of HCL diagnosed in a Thai patient. A 36-year-old man presented with abdominal discomfort, frequent gum bleeding and significant weight loss for 2 months. Physical examination revealed moderate anemia, petechial hemorrhage on the extremities and an enlarged spleen down to the umbilicus. No hepatomegaly or lymphadenopathy was detected. Complete blood counts revealed a hemoglobin (Hb) of 6.6 g/dL, a white blood cell (WBC) count of 1.6 x 10(9)/L (neutrophil 16%, lymphocyte 71%, monocyte 11%, atypical lymphocyte 1%), and a platelet (PLT) count of 17 x 10(9)/L. Abnormal large mononuclear cells with villous projections were seen in the blood smear. Although bone marrow (BM) aspiration resulted in a dry tap, abnormal lymphocytes with villous projections could again be identified in the touch preparation. Flow cytometric analysis showed a distinct population above the normal lymphocyte region on CD45/SSC gates with a strong expression of CD19, CD20, CD22, CD25, CD11c, and kappa. CD5, CD23, CD10, CD4, and CD8 were all negative. BM biopsy was consistent with HCL. The patient was treated with splenectomy followed by 8 cycles of fludarabine and cyclophosphamide chemotherapy. At 21 months after diagnosis, the patient was doing well with a Hb of 16.9 g/dl, a WBC count of 6.8 x 10(9)/L, neutrophil 49.9%, lymphocyte 39.6%, monocyte 8.6%, and a PLT count of 329 x 10(9)/L). No abnormal lymphoid cells were detected in the blood smear. This present report represents the first Thai HCL case that was immunophenotypically confirmed by flow cytometry and successfully treated at Siriraj Hospital.

A 14-day-old neonate was transferred to our university hospital because of respiratory distress and mild disturbance of consciousness. He had no history of abnormal pregnancy or delivery, but had developed apnea at 6 days old. Thereafter, respiratory distress progressed and his condition deteriorated. On admission to our hospital, several vesicles were found on the left upper arm, and moderate hepatomegaly was also present. Herpes simplex virus (HSV) type II genome was detected from serum, spinal fluid, and bone marrow. Laboratory examinations revealed typical abnormalities of disseminated intravascular coagulation, increased levels of serum ferritin, aspartate aminotransferase, and lactate dehydrogenase. Bone marrow aspiration demonstrated activated macrophages and hemophagocytosis. Spinal tap revealed numerous mononuclear cells. Meningitis and virus-associated hemophagocytic syndrome (VAHS) due to systemic HSV type II infection were thus diagnosed. Acyclovir (60 mg/kg/day) and vidarabine were promptly administered. Dexamethasone palmitate and intravenous cyclosporine were also administered for systemic inflammation due to VAHS. Finally, these aggressive therapies rescued the patient without any sequelae. In general, neonatal systemic HSV infection is life-threatening and results in poor intact survival. Our case report suggests that not only antiviral treatment for HSV, but also anti-inflammatory treatment including steroid and cyclosporine should be considered from the early phase of neonatal systemic HSV infection.

A 48-year-old woman was hospitalized because of severe thrombocytopenia, leg edema, and fever. Intravenous immunoglobulin therapy was administered, but no efficacy was obtained. Her bone marrow was dry-tap, and fibrosis was found in the biopsy specimens. A positron emission tomographic study showed FDG-avid lymphadenopathy and hepatomegaly. Biopsy specimens of axillary lymph nodes showed Castleman's disease-like findings. Since she then developed severe proteinuria and massive pleural effusion, steroid therapy was started, providing temporary relief of symptoms other than the thrombocytopenia. However, rapid worsening of her general condition prompted us to attempt rituximab as salvage therapy. The pleural effusion, edema, and proteinuria disappeared soon after starting rituximab administration. Platelet counts also normalized and fibrosis of the bone marrow showed amelioration. Recently, a variant of multicentric Castleman's disease, termed the TAFRO syndrome, has been proposed, and our patient's features fit the diagnosis of this syndrome. Rituximab might be considered as a therapeutic option in such cases.
