The transfusion records of 189 patients with acute leukemia were analyzed to correlate lymphocytotoxic antibody (LCTAb) levels with response to a series of random-donor platelet transfusions (Tx). Twenty-one patients were studied twice at times of different LCTAb levels. All transfusions were given when patients were clinically stable without
disseminated intravascular coagulation
, bleeding, temperature greater than 101 degrees F, or
splenomegaly
. The mean 1-hr and 24-hr corrected count increments (CCI) for all patients with negative LCTAb were 16,100 and 12,000, and values for patients with positive LCTAb were 5,600 and 2,600 (P less than 0.0005). Thirteen patients had intermediate LCTAb (10-20%) and a variable response to Tx. Of the 137 patients with negative LCTAb levels 106 (77%) had good mean CCI of greater than 10,000 at 1 hr and greater than 7,500 at 24 hr following transfusion. In contrast of 60 patients with positive LCTAb (greater than 20% cytotoxicity), 53 (88%) had poor CCI of less than 10,000 at 1 hr and less than 7,500 at 24 hr after transfusion. Only 4 patients with positive LCTAb had a good response to random donor platelets at both 1 and 24 hrs. Eighteen patients had negative LCTAb with a high 1-hr and low 24-hr CCI. Thirteen of these had a history of positive LCTAb and in 9 there was an anamnestic rise following transfusion. Nine of 137 patients had negative LCTAb with low 1-hr and 24-hr CCI. LCTAb is highly predictive of response to random donor platelets. Cytotoxicity to greater than 20% of tested lymphocytes virtually precludes a good CCI at 1 and 24 hr.

8;21 translocation was found in 10 AML patients. These patients exhibited a distinct clinical and haematological picture, characterized by M2 bone marrow, with rather good maturation, a high count of mature granulocytes,
splenomegaly
, and the absence of
DIC
. Complete remission as easily obtained. It was reported that the median survival is better than for other AML patients with abnormal karyotypes, but this could not be substantiated in our small series. The loss of a sex chromosome was found to be frequent and of poor prognostic significance.

Described here is an autopsy case of a 30-year-old woman with systemic hemangiomatosis accompanied by coagulopathy and microangiopathic hemolytic anemia. She had hepato-
splenomegaly
, anemia, thrombocytopenia, prolonged prothrombin time and partial thromboplastin time, and fibrinogenopenia. A splenectomy was performed and a diffuse angioma of the spleen was found. Postmortem examination revealed cavernous hemangiomas and hemangioendotheliomatous lesions in the liver, bone marrow, intestine, and lymph nodes. Coagulation studies suggested that exacerbation of coagulopathy occurred due to Liniac (10MV X-ray) irradiation. Our observation raised the possibility that the irradiation might lead to chronic localized
consumption coagulopathy
, which was confined to the hemangioma, to acute disseminated types of intravascular coagulation.

The diagnosis and management of childhood visceral leishmaniasis were studied in 51 parasitologically proven cases from Abha, Saudi Arabia. Bone marrow aspiration was positive in 40 of 47 cases (85%). Splenic aspiration, though rarely used because of perceived dangers, was not associated with complications and revealed the parasite in all 12 cases in which it was used. There was prompt response to sodium stibogluconate, with defervescence in 93% and decrease of hepatosplenomegaly in 67% of patients within 1 week of commencing chemotherapy. A dose of 20 mg/kg/day for at least 3 weeks was generally safe and effective in achieving cure and preventing relapse. Two children with persistent massive
splenomegaly
after the first course responded to prolonged chemotherapy. Bronchopneumonia and severe cytopenia were common complications.
Disseminated intravascular coagulation
and hepatitis were associated with a poor outcome. The four patients who died had a progressive course with multiple complications. Early detection and appropriate management of complications may help to reduce morbidity and mortality in childhood visceral leishmaniasis.

A 73-year-old man was admitted to our hospital with nasal hemorrhage and high grade fever on Aug, 1992. Physical examination revealed a tumor in the nasopharyngeal cavity, generalized skin eruptions and three tumors on different subcutaneous lesions,
splenomegaly
2 cm below the costal margin, and the enlargement of the right cervical and axillary lymph nodes. Biopsy of the nasopharyngeal and cutaneous tumor disclosed non-Hodgkin's lymphoma (WF: Diffuse small cleaved). Peripheral blood examination showed a WBC of 4,800/microliters with 10% blastoid cells. Bone marrow examination showed 60% blastoid cells which frequently appeared a hand mirror configuration had no azurophilic granules in the cytoplasm. Flow cytometic analysis of these cells in the bone marrow showed that they expressed CD56 (NKH-1) and Ia but not expressed T-cell antigens as well as B-cell antigens and myeloid cell antigens. Phenotype of subcutaneous tumor biopsy cells was similar to that of blastoid cells in the bone marrow. T-cell receptor gene (TCR beta and gamma) rearrangements in blastoid cells were not found. The patient was treated with local radiotherapy to nasopharyngeal and skin tumors, followed by chemotherapy. The patient died of complication with pulmonary bleeding due to
DIC
. These results suggested that this nasopharyngeal lymphoma derived from NK cell.

We report a 20 year-old woman with hemophagocytic syndrome. In February 1993, she developed high fever, arthralgia, salmon-like pink eruption, leukocytosis and
splenomegaly
. She was diagnosed as adult Still's disease and successfully treated with intravenous immunoglobulin and oral prednisolone. In September 1993, she was re-admitted to our hospital complaining of general fatigue and low grade fever and treated with oral prednisolone at a daily dose of 15 mg. On October 2, 1993, she suddenly developed high fever and salmon-like pink eruption on her leg followed by the marked increase of serum transaminase and LDH levels (GOT 3,270 IU/l, GPT 1,880 IU/l, LDH 5,480 IU/l) on October 7. Since hepatic failure progressed, we started methylprednisolone pulse therapy and plasmapheresis. However, because of the progression of pancytopenia caused by hemophagocytosis, the treatment with VP-16 was initiated. However, she died of
DIC
on November 2, 1993. Autopsy revealed submassive necrosis of the hepatocytes with moderate infiltration of histiocytes. She was retrospectively diagnosed as hemophagocytic syndrome whose manifestations are very similar to those in adult Still's disease and acute viral hepatitis.

We report herein the case of a 19-year-old woman, diagnosed as having Klippel-Trenaunay syndrome at the age of 3 years, who presented to our hospital with severe abdominal pain. Abdominal computed tomography revealed
splenomegaly
, ascites, and paracentesis confirming an intraabdominal hemorrhage. Thus, an emergency laparatomy was performed for a suspected splenic rupture, and 2.5 L of blood was drained from the abdominal cavity.
Splenomegaly
was confirmed, and a splenectomy was performed. The patient's postoperative course was complicated by
disseminated intravascular coagulation
, but she recovered and was discharged 3 weeks following surgery. Pathological examination of the spleen suggested that the
splenomegaly
was caused by high venous pressure due to splenic vein stenosis. To our knowledge, this is the first reported case of Klippel-Trenaunay syndrome associated with marked
splenomegaly
.

The clinical characteristics and treatment outcome in 40 children with acute promyelocytic leukemia (APL) treated at institutions participating in the Children's Cancer and Leukemia Study Group (CCLSG) were studied retrospectively. The median age at diagnosis was 8 years old. Bleeding diathesis was the predominant presenting symptom (90%), associated with laboratory findings of
disseminated intravascular coagulation
. Hepatomegaly,
splenomegaly
and lymphadenopathy were observed in 35%, 10%, and 15% of the cases, respectively. The median WBC count was 4.25 x 10(9)/l. Anemia (hemoglobin < 8 g/dl) and thrombocytopenia (< 30 x 10(9)/l) were present in more than half of the patients. Cytogenetic studies demonstrated the characteristic 15; 17 translocation in about 90% of the patients analyzed. Induction therapy consisted of cytosine arabinoside and an anthracycline, with or without other agents. Twenty-nine patients (73%) achieved complete remission (CR) while early fatal hemorrhage was the predominant cause of induction failure. The survival rates continued to decrease (28% at 3 years, 24% at 5 years, and 7.9% at 10 years) due to late marrow relapses. Anthracycline cardiotoxicity was fatal in three patients in remission. These clinical features of childhood APL should be taken into account in the development of new protocols.

Platelet crossmatching may provide a useful way of selecting donors for effective platelet transfusions in patients refractory to random donor platelet concentrates due to alloimmunization. We assessed the predictive value of a flow cytometric platelet immunofluorescence crossmatch test for the outcome of HLA matched platelet transfusions in a group of alloimmunized patients. Platelet immunofluorescence (PIFT) crossmatches were performed for 104 HLA-matched platelet transfusions administered to 30 patients. A negative PIFT crossmatch correctly predicted a successful platelet transfusion (1 h post-transfusion platelet recovery >20%) in 56/75 (75%) cases. We also considered non-immunological factors that, in combination with alloimmunization, might have contributed to an unsuccessful transfusion result, i.e. fever, septicaemia,
splenomegaly
,
disseminated intravascular coagulation
and bleeding. The predictive value of a negative PIFT crossmatch was better when these non-immunological factors were absent [48/59 (81%) correct predictions] than when these factors were present [8/16 (50%) correct predictions] (P=0.01; chi-square test). The effect of ABO incompatibility between donor and recipient on the predictive value of the PIFT crossmatch was also analysed. Positive PIFT crossmatches occurred more frequently in ABO incompatible donor-recipient combinations [in 18/28 (64%) cases] than in ABO-compatible donor-recipient combinations [in 11/76 cases (14%)] (P<0.001, chi-square test). Successful platelet transfusions were observed on 53/76 (70%) occasions in ABO compatible transfusions as compared to 16/28 (57%) in ABO incompatible transfusions. This difference was not statistically significant (P=0.23; chi-square test). Consequently, a negative PIFT crossmatch appeared to be non-predictive for the transfusion outcome in cases of ABO incompatibility between donor and recipient. We conclude that the PIFT crossmatch for platelet donor selection in addition to matching for HLA antigens, is predictive for the outcome of ABO compatible transfusions in alloimmunized recipients and prediction levels are increased when non-immunological causes for platelet refractoriness are absent.

A 60-year-old Japanese woman was admitted to our hospital because of fatigue, weight loss and abdominal distension. Myelofibrosis was diagnosed, based on anemia, huge hepatosplenomegaly, leukoerythroblastosis and bone marrow fibrosis. Following treatment with ranimustine, anemia and
splenomegaly
improved. Seven months after initial therapy of ranimustine, however, polycythemia (RBC 7.39 x 10(6)/microliter; Hb 19.1 g/dl, Ht 65.9%) developed gradually, then RBC decreased to normal level following venesection (total 1,200 ml). After 32 months, blastic transformation occurred. The blasts were negative for myeloperoxidase. By flow cytometric analysis, the cells were positive for CD2, CD13, CD33 and HLA DR. Thus, AML (M0) was diagnosed. Despite of treatment with multicytotoxic agents, she died of
DIC
36 months after the initial diagnosis of myelofibrosis. The progression from myelofibrosis to polycythemia is rare and only 15 cases have been reported so far. In addition, although a chromosomal abnormality, 46, XX, t(3; 12) (q25; p11), was present at the time of first diagnosis of myelofibrosis, the development of an additional abnormality, del(11) (q-), might be related to the transformation to AML.
