We report five cases that presented with high fever, anasarca, hepatosplenomegaly and severe thrombocytopenia with reticulin fibrosis of the bone marrow. The constellation of symptoms is not compatible with any known disease, and we had difficulty in diagnosis and treatment. The age distribution was from 47 to 56 years, and two men and three women were affected. Two patients needed hemodialysis because of renal dysfunction and oliguria with massive pleural effusion. Laboratory examinations showed normal immunoglobulin levels and no monoclonal protein. None of them showed diagnostic autoantibodies for any autoimmune diseases. Histological examination of the liver in three patients and spleen in two showed non-specific findings. Lymphadenopathy was tiny and lymph node biopsy was carried out in only one case. Histologically, paracortical hyperplasia with vascular proliferation and atrophic germinal centers resembling hyaline-vascular-type Castleman's disease or POEMS syndrome were detected. Without a definitive diagnosis, treatment was started with cyclophosphamide, hydroxydaunorubicin, vincristine and prednisolone (CHOP) regimen in one patient, semi-pulse therapy with methyl-predonisolone in three and cyclosporin A in three. Two patients achieved complete remission, two were steroid-dependent and the remaining one died of multiple organ failure. These findings suggest that this disease may be a novel clinical entity belonging to systemic inflammatory disorder with a background of immunological abnormality or a unique variant of multicentric Castleman's disease.

We describe 3 patients with acute myeloblastic leukemia (AML), who received rhG-CSF for infections such as pneumonia or for prophylaxis of infection, and who achieved complete remission. They had not received any antileukemic therapy before or during the administration of rhG-CSF. These findings suggest the possibility that complete remission can be brought about by G-CSF itself in some patients with AML.
A 73-year-old womanwas diagnosed as primary hyperparathyroidism. Hypercalcemia recurred after parathyroidectomy, though serum calcium concentration temporarily resumed to normal. Hypercalcemiawas eventually shownto be due to multiple myeloma.In spite of the frequent association of hypercalcemia with malignant disease and the relative frequency of primary hyperparathyroidism as a cause ofhypercalcemia, primary hyperparathyroidism accompanied by multiple myelomahas been considered in only a limited number of reports. Here, the cases in the literature are reviewed and discussed. (Internal Medicine 34: 988-991, 1995)
This retrospective analysis investigated the prognostic value of monitoring the response to imatinib using peripheral blood (PB) samples and the impact of the response on outcome in 133 patients with chronic myeloid leukemia (CML). We divided the response into 3 categories according to the results of neutrophil (N)-FISH and BCR-ABL transcript levels in PB; more than a 3-log reduction [major molecular response (MMR)], between a 2-log and 3-log reduction or negative with N-FISH [complete cytogenetic response equivalent (CCyRe)], N-FISH positive or less than a 2-log reduction (non-CCyRe). The median follow-up was 5.46 years. At 5 years, the overall survival (OS) rate and progression-free survival (PFS) rate were 94.4 and 92.0%, respectively. The estimated rate of the CCyRe and MMR were 81.7 and 67.1%, respectively. 106 patients achieving the CCyRe had significantly better OS and PFS than 27 patients without achieving the CCyRe. Patients with MMR had significantly better survival free from death, progression, imatinib withdrawal and a loss of the CCyRe, than patients whose response level remained in the CCyRe without achieving MMR until 18 months. Our observation suggests that the response level of the CCyRe on PB serve as a prognostic indicator, and achieving MMR provides stable long-term survival.
We report the case of 61-year-old woman with cryptogenic liver abscesses who had been profoundly ill with severe upper abdominal pain, impaired consciousness, prostration, continuous high fever secondary to sepsis, and thrombocytopenia (platelets, 1-5 x 10(4)/mm3) since admission. Ultrasonograms and computed tomograms revealed two separate multiloculated lesions in the right lobe of the liver, consistent with the liver abscesses. Immediately after diagnosis, percutaneous abscess drainage was performed under ultrasonographic guidance; however, only a small amount of pus was drained, prompting continuous irrigation of the abscess cavity. Four days later, transcatheter hepatic arterial infusion of antibiotics was attempted. However, the abscesses had enlarged and her general condition had worsened. On hospital day 8, she underwent right hepatectomy because the multiloculated lesions were refractory to drainage. The operation was successful in terms of hepatectomy, although she continued to suffer from sepsis, secondary right subphrenic abscess formation, and prolonged thrombocytopenia with associated coagulation disorders for two months. Examination of multiple cross sections of the resected specimen disclosed that the lesions consisted of aggregations of multiple small locules. There was no communication between the locules and there were true septations, rather than multiloculated lesions with pseudoseptations. The patient has been well for 2 years without recurrent abscess of the liver or any infectious disease.
We present a case of classical Hodgkin's lymphoma (HL) co-occurring with histological features of Castleman's disease (CD). A 25-year-old man presented with left supraclavicular and axillary lymph node swelling and mediastinal mass. Using an initial biopsy specimen from left axillary lymph node, a tentative diagnosis of multicentric CD of plasma cell type was made. The serum level of interleukin-6 (IL-6) was elevated. The patient was treated with immunosuppressive therapy containing tocilizumab (TCZ). Shrinkage of mediastinal mass and axillary lymph nodes was seen; however, swelling of his left axillary lymph nodes reemerged, even after therapy with TCZ. A second left axillary lymph node biopsy was performed and a diagnosis of nodular sclerosis of classical HL without histologic features of CD was made. The initial biopsy specimen was re-examined, and scattered CD30+ Hodgkin/Reed-Sternberg cells were found in the interfollicular area. Interestingly, Hodgkin/Reed-Sternberg cells and surrounding reactive cells in both lymph nodes were stained with anti-IL-6 antibody. We emphasize that biopsy specimens with HL involvement may also have histologic features reminiscent of those seen in CD. To our knowledge, this is the first report to provide a detailed description of this pathology, including a survey of IL-6 and clinical course upon treatment with TCZ.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
