1/2567. Acute transient radiation hepatitis following whole abdominal irradiation.

    Sporadic cases or radiation hepatitis have been reported following doses above 3500 rad delivered in 3-4 weeks to the liver. The authors report their experience of radiation hepatitis in two out of 117 consecutive lymphoma cases treated with total abdominal irradiation. These two patients developed clinically overt manifestations which lasted for a short period of time and fully recovered. The dose delivered to the whole liver was 3000 rad in six weeks, but in one an additional 1000 rad in five fractions were delivered to the left lobe in an attempt to boost the dose to the central axis lymphatic system up to 4000 rad. The low incidence of radiation hepatitis and its reversible course, when 3000 rad in six weeks are delivered to the whole liver, is emphasised. ( info)

2/2567. A case of primary lymphoma of the liver.

    A case of primary malignant lymphoma of the liver is described. Presenting with epistaxis, he died in hepatic encephalopathy with an intractable bleeding post-bulbar duodenal ulcer. ( info)

3/2567. Signet-ring cells in a Waldenstrom's Macroglobulinaemia.

    A case of signet-ring cell lymphoma affecting bone marrow is reported. The patient was diagnosed as Waldenstrom's Macroglobulinaemia on the basis of clinical and laboratory features including morphology, immunohistochemistry and gene rearrangement studies. light microscopy examination showed cells contained large globular inclusions (signet-ring cells) that stained for kappa immunoglobulin light chain by immunohistochemistry. In addition, the neoplastic cells expressed the common leukocyte antigen CD45 and the B cell marker CD19. This to the best of our knowledge is the first report of a patient with Waldenstrom's Macroglobulinaemia with the presence of vacuolated signet ring- cells in the bone marrow. Differential diagnosis arises with non-haemopoietic tumours and this needs to be based on specific immunostaining. Tumours and this need to be based on specific immunostaining. ( info)

4/2567. Bone marrow examinations as final clue to diagnosis of hypercalcemia: report of two cases.

    Two young men with severe hypercalcemia in association with renal failure (one acute and one chronic) are reported in whom usual diagnostic tests failed to reveal an etiology, and the final diagnoses were given by bone marrow examinations. Early bone marrow examinations in specific patients with hypercalcemia of undetermined origin sometimes are vital as shown by our two patients. ( info)

5/2567. Antifungal susceptibility of aspergillus species isolated from invasive oral infection in neutropenic patients with hematologic malignancies.

    OBJECTIVE: The aim of this study was to evaluate the relevance of in vitro antifungal susceptibility to clinical response in neutropenic patients with invasive oral aspergillosis. STUDY DESIGN: Nine isolates of aspergillus species were obtained from invasive oral infections in 9 patients with hematologic malignancies and tested for their in vitro susceptibility to amphotericin b, fluconazole, miconazole, 5-fluorocytosine, and itraconazole. Minimal inhibitory concentration values of the 5 drugs were obtained for each fungus through use of a microdilution broth method. The patients were treated with intravenous amphotericin b (30-50 mg/day) in combination with oral 5-fluorocytosine (3000-6000 mg/day) and/or oral itraconazole (200 mg/day). RESULTS: amphotericin b and itraconazole were found to be very active, with minimal inhibitory concentration values of 0.861 and 0.194 microg/mL, respectively. miconazole and 5-fluorocytosine showed minimal inhibitory concentration values of 1.72 and 3.56 microg/mL, respectively. On the other hand, fluconazole FCZ showed low activity, with a minimal inhibitory concentration value in excess of 64.0 microg/mL. During neutropenia, combined antifungal chemotherapy stabilized oral aspergillosis and prevented the spread of oral lesions in 8 patients in whom neutrophil counts eventually recovered. CONCLUSIONS: The results imply that in vitro susceptibility testing may serve as an informative parameter with respect to the efficacy of these antifungals in the treatment of invasive oral aspergillosis, inducing fungal stasis until the neutrophils recover.

6/2567. Autologous bone marrow transplantation for recurrent malignant lymphoma after liver transplantation.

    BACKGROUND: Cancer chemotherapy in chronic carriers of hepatitis b virus is known to promote viral replication, and, when immunosuppressive treatment is stopped, the return of immune competence can be followed by a fulminant hepatitis. liver transplantation may be required and has been successfully performed for this condition. However, malignancy recurrence after transplantation has not been reported yet. methods AND RESULTS: We here report the case of an asymptomatic hepatitis B surface antigen carrier who developed a malignant lymphoma, which was treated by chemotherapy. After cessation of chemotherapy, he developed a fulminant hepatitis, requiring liver transplantation. Three years later, he developed a recurrent malignant lymphoma, which was treated successfully by autologous bone marrow transplantation. In order to prevent viral replication, lamivudine and intermittent administration of fresh-frozen plasma highly concentrated in anti-HBs immunoglobulin was initiated before the bone marrow transplantation. The patient remains well 12 and 56 months after autologous bone marrow and liver transplantation, respectively. CONCLUSIONS: This experience suggests that all hepatitis B surface antigen-positive patients for whom chemotherapy is indicated would benefit from prophylactic antiviral hepatitis b virus therapy. Furthermore, successful autologous bone marrow transplantation is possible after liver transplantation. ( info)

7/2567. Nodular lymphoid lesion of the liver: an immune-mediated disorder mimicking low-grade malignant lymphoma.

    Three cases of unusual lymphoid infiltrate forming nodular macroscopic masses in the liver were studied in the authors' surgical pathology laboratory. These lesions posed difficulty in diagnosis, and their differentiation from low-grade lymphoma was not possible on histopathologic evaluation alone. The liver masses were analyzed histologically and immunohistochemically as well as for clonal immunoglobulin heavy chain (IgH) and T-cell receptor gamma (TCR-gamma) gene rearrangements. The lesions were seen as solitary grossly distinct firm nodules in all three patients, measuring 0.4, 0.7, and 1.5 cm, respectively, in their greatest dimensions. Two were found in livers removed because of end-stage primary biliary cirrhosis at the time of orthotopic liver transplantation, and the third was an incidental finding during laparotomy. Microscopically, these were nodules composed of small lymphocytes, plasma cells, and immunoblasts, with varying degrees of admixed acute inflammatory cells and scattered lymphoid follicles. By immunohistochemistry and molecular studies, these were found to be reactive lymphoid proliferations. All patients are alive and well at 2, 4, and 13 years, respectively. It is concluded that these cases represent a unique type of nodular lymphoid lesion, which is probably an immune-mediated benign reactive hyperplasia. It constitutes an entity by itself and must be distinguished from low-grade lymphoma. For a definitive diagnosis, immunohistochemistry and molecular studies are required. ( info)

8/2567. Herpesvirus 8 inclusions in primary effusion lymphoma: report of a unique case with T-cell phenotype.

    We describe a case of primary effusion lymphoma with T-cell phenotype, mixed genotype, and intranuclear herpesvirus inclusions visible with the light microscope. Cells were studied by immunohistochemical analysis, in situ hybridization, immunoglobulin and T-cell receptor gene rearrangement, and polymerase chain reaction. Primary effusion lymphoma cells with T-cell phenotype revealed herpesvirus 8 inclusions predominantly seen in apoptotic cells, suggesting that productive viral infection is associated with cell death. Clinical features were typical of primary effusion lymphoma. Cytologic, molecular genetic, and phenotypic features demonstrated a unique variant of primary effusion lymphoma. ( info)

9/2567. Spontaneous gastrointestinal perforation in patients with lymphoma receiving chemotherapy and steroids. Report of three cases.

    Spontaneous gastrointestinal perforations in three patients with lymphoma were considered to be treatment-related conditions. All three were diagnosed as having malignant lymphoma by histological examination, and treated with chemotherapy and steroids. Four to 14 days after the start of chemotherapy, they complained of abdominal pain and plain roentgenograms revealed pneumoperitoneum. The interval between the onset of peritonitis and operation was almost 24 h. Emergency operations were carried out; one patient with a jejunal perforation underwent resection of the jejunum, another with a gastric perforation received a simple closure with omental patch, and the third with a gastric perforation underwent gastrectomy. Two patients recovered from the surgery, while the gastrectomy patient died due to sepsis. The favorable outcome of the surgical intervention is attributed to early diagnosis, prompt exploration, and selective operative procedures. We recommended a simple closure with omental patch for gastroduodenal perforation. Resection and primary anastomosis are possible only in the small bowel. ( info)

10/2567. Non-Hodgkin's lymphoma terminating in acute myelogenous leukemia.

    The number of patients with non-Hodgkin's lymphoma who develop acute myelogenous leukemia is relatively small. The case of a patient with histologically proven diffuse histiocytic lymphoma who died with unequivocal acute myelogenous leukemia 5 years after the lymphoma diagnosis is presented. The difficulties in differential diagnosis are cited with a review of the literature. ( info)
