We report the case of a 40-yr-old man presenting with symptoms of small bowel obstruction. Small bowel x-rays revealed a stricture of the mid-jejunum. Push enteroscopy found a polypoid mass at 1 meter of the ligament of Treitz. Histopathological examination of the biopsy and surgical specimens showed a diffuse infiltrate of the mucosa made of medium to large cells, which were stained on immunohistochemistry by the leucocyte marker CD45 and the histiocyte/monocyte marker CD68 but were negative for the B and T cell markers. Cytological examination of the ascitic fluid revealed many myelobasts with cytoplasmic Auer rods and positive myeloperoxidase staining. There was no evidence of blood or bone marrow involvement suggestive of acute leukemia or myeloproliferative disorders. These findings were consistent with the diagnosis of preleukemic granulocytic sarcoma (or chloroma). Chemotherapy led to complete remission, but 21 months later the patient developed an acute myeloid leukemia. He died from aspergillus pneumonitis, 10 months after bone marrow allograft. Preleukemic granulocytic sarcoma of the small bowel is a rare condition and its diagnosis is usually not easy, requiring histochemical or immunohistochemical studies. Most cases have progressed to acute myeloid leukemia. 相似文献

Eleven patients, 13 to 76 (mean, 40) years of age, had granulocytic sarcoma of the female genital tract (FGT) (ovary, seven cases; vagina, three cases; cervix, one case). In nine cases, the FGT involvement was the initial clinical presentation of the disease, and in the other two cases, the FGT involvement was discovered during a relapse of acute myeloid leukemia. The tumors ranged from 0.5 to 14 (mean, 7.5) cm in greatest dimension. Two ovarian tumors were bilateral, and three were green. Microscopic examination revealed a predominantly diffuse pattern of growth, but cords and pseudoacinar spaces were also present focally in several cases. Sclerosis was seen in five tumors and was prominent in one. Prominent myeloid differentiation was readily recognizable on routinely stained sections in three cases, whereas the neoplastic cells in the other cases were primitive with only rare eosinophilic myelocytes. All 11 tumors were positive for chloroacetate esterase, nine of nine were strongly and diffusely positive for lysozyme, eight of eight for myeloperoxidase, seven of seven for CD68, and six of six for CD43. Examination of bone marrow or peripheral blood performed after the diagnosis of FGT involvement revealed acute myeloid leukemia in three of five cases. Two of these patients died of disease, 1 and 16 months after the initial diagnosis, and the third, who received chemotherapy, is alive and free of disease 8 months after the initial diagnosis. One of the two patients with negative bone marrow had recurrent granulocytic sarcoma 30 months after diagnosis and died of sepsis 1 month later; no residual disease was noted at autopsy. The other patient is alive and free of disease 18 months after the diagnosis. One of the four remaining patients with primary FGT involvement who did not have a bone marrow biopsy died of leukemia 24 months later; no follow-up information is available for the other three patients. One of the two patients with a prior diagnosis of acute myeloid leukemia was alive with disease 26 months later; follow-up is not available for the second patient. The diagnosis was often difficult in these cases, the most common problem being distinction from malignant lymphoma, but carcinoma, granulosa cell tumor, and, rarely, other tumors were considered. Immunohistochemical and enzyme histochemical staining were useful in establishing the diagnosis, although suspicion of the diagnosis on examination of routinely stained sections was of paramount importance. 相似文献

Bone marrow involvement by anaplastic large cell anaplastic large cell (ALC) lymphoma can be difficult to detect on routine morphologic examination alone. In a series of 42 patients with ALC lymphoma, the authors analyzed: (1) the usefulness of a limited panel of monoclonal antibodies directed against CD30 (Ber-H2, HRS4) and epithelial marrow involvement on routinely processed biopsy specimens; and (2) the prognostic significance of bone marrow involvement as detected on both morphologic and immunohistochemical grounds. On conventional examination, 17% of the patients were found to have bone marrow involvement at diagnosis. However, after immunohistochemical analysis, occult malignant cells were detected in 23% of the patients with negative bone marrow biopsy on routine histology. The low percentage of positive cases on routine morphologic examination compared to immunohistochemical examination was related to: (1) the scarcity of neoplastic cells which were scattered among hematopoietic cells; (2) the difficulty of distinguishing malignant cells from immature hematopoietic elements; and (3) the absence of alteration of the reticulin network. The authors observed a significant association between marrow infiltration and the presence of hematologic abnormalities (mostly anemia or cytopenias) at diagnosis, both in children and adult patients. More importantly, a significant lower survival was seen in patients with bone marrow involvement compared to those without bone marrow involvement. Immunohistochemistry with anti-CD30 and anti-EMA antibodies should be performed systematically in bone marrow biopsies from patients with ALC lymphoma to reliably identify the presence of bone marrow involvement that appears to carry a poor prognosis. 相似文献

The authors describe a patient with a long-standing history of systemic lupus erythematosus and leukopenia who received multiple intermittent doses of recombinant granulocyte colony-stimulating factor (G-CSF) and who underwent splenectomy because of a clinical impression of sequestration of granulocytes by the spleen. Histologic evaluation of the spleen revealed marked granulocytic hyperplasia with an increase in immature myeloid precursors, morphologically indistinguishable from a myeloid leukemic infiltrate. A postsplenectomy bone marrow aspirate and biopsy revealed a normocellular bone marrow with active hematopoiesis and trilineage maturation. The bone marrow aspirate cultured cells showed no numeric or structural chromosomal abnormality. Extramedullary hematopoiesis after receipt of G-CSF was previously reported, but, to our knowledge, ours is the first report of morphologic changes virtually identical to a leukemic infiltrate in spleen after G-CSF treatment. We describe the histologic and immunohistochemical findings in the spleen, compare our observations with those of others reported in the literature, and postulate a possible mechanism for this phenomenon. 相似文献

p53 overexpression was studied immunohistochemically in paraffin-embedded bone marrow biopsies using a recently described technique for antigen retrieval based on microwave oven heating of paraffin sections. Using a monoclonal antibody (PAb1801) that reacts with human cellular p53, nuclear staining was detected in 7/11 (63%) therapy-related myelodysplastic syndromes and in 3/4 (75%) therapy-related acute myeloid leukemias. Conversely, staining for p53 was seen only in 9/40 (22%) cases of "primary" hematologic conditions (P < 0.007); these included myelodysplastic syndromes [#2], acute myeloid leukemia [#4], and chronic granulocytic leukemia in accelerated phase or blast crisis [#3]. Biopsies of normal controls and of chronic granulocytic leukemia in stable phase were consistently p53(-). Nine of the 10 karyotyped p53(+) acute myeloid leukemia/myelodysplastic syndrome cases showed complex cytogenetic findings with frequent involvement of chromosome 5 and/or 7. Only four of the 33 karyotyped p53(-) cases showed similar cytogenetic changes. Chromosome 17 involvement was present in four of 13 (31%) cytogenetically assessed p53+ cases, but in none of the p53(-). In univariate analysis, p53 expression in both MDS and AML was significantly associated with shorter survival. The frequent overexpression of p53 in therapy-related myelodysplastic syndromes, therapy-related acute myeloid leukemias and in accelerated phase/blast crisis, chronic granulocytic leukemia and its strong association with complex karyotypes suggests an important role of this gene in the pathogenesis of these leukemic conditions. 相似文献

BACKGROUND: Granulocytic sarcoma is more frequent in adults; it can be a tumoral localization of acute non-lymphoblastic leukemia. This report describes an infantile case revealing an acute myeloid leukemia. CASE REPORT: A 14 month-old girl was admitted because of enlarged bilateral cervical lymph nodes. They had increased in volume over the past month and were accompanied by fever and anorexia. The liver and spleen were moderately enlarged. Hematologic data were: Hb = 7.5 g%; leucocytes = 14,900/mm3; platelets = 614,000/mm3. There were no abnormal cells. X-rays and MRI showed a mediastinal mass. Bone scintigraphy was normal but the myelogram showed a few atypical cells that were also seen in a biopsy of the cervical lymph node. Electron microscopic examination of these cells showed that they were myeloid in origin. This was confirmed by immunohistochemistry. The cytogenetic examination showed many chromosomal abnormalities in the lymph node and myelogram. The child is now recovered after nine months of chemotherapy. CONCLUSION: Diagnosis of acute myeloblastic leukemia in children is difficult when it is revealed by granulocytic sarcoma without major infiltration of bone marrow. The clinical presentation as a mediastinal mass is rare. The cytogenetic study was determinant for diagnosis. 相似文献

Interdigitating cell sarcoma is an extremely rare tumor. Its presentation and histologic appearance has varied among the reported cases. In this study, the authors investigated four cases of the hematolymphoid malignancy arising within lymph nodes, which were considered to be of interdigitating cell origin. All patients presented in the 6th to 8th decade of life with peripheral lymphadenopathy, and had a relatively indolent clinical course, without bone marrow or skin involvement. Carcinomas were observed as a second neoplasm in two of four patients. Distinctive morphologic features are proliferation of histiocyte-like cells with nuclear pleomorphism and occasionally multinucleated, paracortical distribution sparing of B-cell regions, fibrosis, sinus infiltration, and a prominent eosinophil/plasma cell infiltrates. The combination of light microscopic, fine structural, and immunohistochemical features suggested that these tumors derive from interdigitating cells; these tumor cells expressed CD68 (KP1), S-100 protein and HLA-DR, but lack CD21 (1F8), desmosomes and Birbeck granules. The diagnosis of interdigitating cell sarcoma should be considered on any pleomorphic tumor with the features described in this report. 相似文献

Analysis of non-Hodgkin lymphoma (NHL) involvement of bone marrow trephine biopsy specimens by morphologic features and immunohistochemistry is often difficult, and the criteria for involvement are ill defined. We compared the morphologic and immunohistochemical analysis of B-cell NHL involvement with immunoglobulin heavy chain gene (IgH) rearrangement analysis by polymerase chain reaction (PCR) amplification of the complementarity determining region 3 (CDR3) in bone marrow biopsy specimens from patients with mantle cell lymphoma (n = 53) or hairy cell leukemia (n = 71). By combing morphologic features and phenotype, 54 specimens were considered positive, 62 negative, and 8 inconclusive. PCR analysis showed clonal IgH rearrangements in 46 positive and 6 inconclusive specimens. No clonal IgH rearrangements were present in 61 negative specimens. The 1 false-positive and most false-negative PCR results were likely due to sampling error or DNA degradation of the fixed tissues. In most cases, bone marrow involvement by NHL can be identified by histologic and immunohistochemical examination. Furthermore, clonality of the B-cell population can be detected by amplification of the IgH CDR3 on DNA extracted from bone marrow trephine biopsy sections, which can be helpful in cases diagnosed as inconclusive. 相似文献

Two cases of acute myeloid leukemia (AML) presenting with bulky adenopathy are reported. Both patients were febrile at admission and showed massive and diffuse lymph node involvement, hepatomegaly, and splenomegaly. Erythematopapular leukemic skin lesions were present in one case at the onset and developed in the other at the time of relapse. Anemia, thrombocytopenia, and moderate leukocytosis were present in both. The presence of immature cells in peripheral blood and bone marrow allowed a rapid diagnosis of AML, FAB M1, in one patient. In the other case, owing to the paucity of immature cells in peripheral blood and bone marrow, lymph node biopsy with histology, imprint cytology, and immunocytochemistry were essential for the diagnosis (AML, FAB M2, with trilineage dysplasia and basophilic involvement). Both patients achieved complete remission (CR), followed by an early relapse 3 months later. They underwent allogeneic bone marrow transplantation (BMT) from HLA identical siblings. One patient is actually alive and in CR at 6 months after BMT; the other patient showed a leukemic regrowth after transplantation and died 4 months later. 相似文献

A 48-year-old female who had general fatigue was admitted to our hospital. She had swelling of the axillary, inguinal, and paraaortic lymph nodes and mediastinal lesions. Laboratory examinations showed anemia, polyclonal hyperimmunoglobulinemia with IgG 5570 mg/dl, renal dysfunction and interstitial changes of the lungs. Microscopic findings of hematoxylin-eosin staining in biopsy specimens of the left inguinal and axillary lymph nodes revealed increased levels of infiltration of mature plasma cells without evidence of malignancy. Immunoperoxidase staining showed intracytoplasmic polyclonal immunoglobulin. These findings were identical to those of idiopathic plasmacytic lymphadenopathy with polyclonal hyperimmunoglobulinemia (IPL) described by Mori et al. (1980). The specimens also showed evidence of chronic nephritis with infiltration of lymph cells and a slight invasion of plasma cells. Accordingly this case was diagnosed as IPL with renal involvement, which is associated with chronic nephritis. Recently, five cases of IPL with renal dysfunction have been reported. In particular, two cases of IPL with renal dysfunction, which included our case, revealed an increased level of IL6. These findings suggest that the occurrence of renal involvement with IPL may be related to changes in IL6, which is an important factor in the pathogenesis of IPL. 相似文献

A considerable proportion of cases of myeloproliferative and lymphoproliferative disorders exhibit renal involvement. However, it is unclear whether the cytologic features, immunophenotype or grade of malignancy of the cells infiltrating the kidney differ from those of the primary tumor. This study was performed on 120 autopsy cases with the following diagnoses: acute myelogenous leukemia (AML, n = 22; subtypes M1 + M2, n = 12, subtype M4, n = 10), chronic myelogenous leukemia (CML, n = 7), agnogenic myeloid metaplasia/myelofibrosis (AMM/MF, n = 6), acute lymphocytic leukemia (ALL, n = 6), chronic lymphocytic leukemia (CLL, n = 9), other low-grade non-Hodgkin's lymphomas (low-grade NHL, n = 24), high-grade NHL (n = 21) and multiple myeloma (MM, n = 25). Renal involvement was investigated by light microscopy and immunohistochemistry. It was found in 34% of the cases, and was most common in ALL (83%) and low-grade NHL (50%) and least common in high-grade NHL (10%) and MM (12%). Dense infiltration of almost the entire kidney was most commonly seen in AML, low-grade NHL and ALL. Infiltration was bilateral and involved both the cortex and medulla in the majority of cases. When involvement of other organs was compared with that of the kidney, the lung was found to be involved in approximately the same number of cases, but liver involvement was more common and heart involvement less common. Reactive lymphocytic infiltration of the kidney was found in 18 of the 120 cases (15%), and was distinguished from scanty tumorous infiltration by immunohistochemical staining. No major phenotypical differences were found between the tumor cells infiltrating the kidney and those of the primary tumors in the bone marrow or lymph nodes. However, in one case of CML, the cells infiltrating the kidney were negative for KP1 and chloroacetate esterase, but could be identified by reactivity for CD34. The grade of malignancy in NHL was similar in both the nodal and renal manifestations. 相似文献

The cell morphology and karyotype of bone marrow samples from 24 patients with myelodysplastic syndrome (MDS) and acute myeloid leukaemia (AML) were studied simultaneously with a combined technique of May-Grünwald-Giemsa (MGG) staining and fluorescence in situ hybridization (FISH) with chromosome-specific DNA probes. This enabled us to investigate cell lineage involvement in three malignant conditions: MDS (n = 12), leukaemia-transformed MDS (LT-MDS) (n = 5) and de novo AML (n = 7). In MDS we found blasts and often significant proportions of mature granulocytic and erythroid cells to be cytogenetically abnormal. Percentages of granulocytic and erythroid cells with cytogenetic aberrations were generally less than those of blasts. These data support the involvement of a transformed pluripotent stem cell that has retained maturation abilities. In two patients with chronic myelomonocytic leukaemia (CMMoL) the clonal involvement of monocytes was predominant. Results in the five patients with LT-MDS were similar to those in MDS. In the bone marrow of five of the seven de novo AML patients the cytogenetic abnormalities were restricted to the blasts and did not include the more mature granulocytic or erythroid populations. In the other two patients with AML, both with a t(8;21) and a loss of the Y chromosome, high percentages of mature neutrophils were cytogenetically abnormal. These patterns of clonal lineage involvement in MDS, LT-MDS, t(8;21) AML and AML appear typical and may be of clinical use, for example, for distinguishing LT-MDS from de novo AML in newly presenting patients. 相似文献

To evaluate the feasibility of acute leukemia typing on routinely processed bone marrow biopsy specimens, 72 cases of previously established acute leukemia covering the spectrum of 17 known subtypes were studied immunohistochemically. Most leukemic myeloblasts were positive for myeloperoxidase in 16 (84%) of 19 cases of acute myeloid leukemia, M1-M4, and M6. Most leukemic cells in 11 of 12 M4 and M5 cases were positive for CD68 (PG-M1). All six M6 cases stained with hemoglobin. Leukemic megakaryoblasts in three of four M7 cases were positive for factor VIII-related antigen. Almost all leukemic cells of 8 T-lineage acute lymphoblastic leukemia (ALL) and 19 B-lineage ALL cases were positive for CD3 and CD79a (HM57), respectively. Staining with CD20 (L26) was positive in the more differentiated B-lineage ALL cases and strongest in L3. Immunohistochemical typing of acute leukemia is possible for most types using this panel of cell lineage-specific antibodies. 相似文献

Amyloid involvement of the bone marrow is not commonly diagnosed before necropsy. Paraffin sections of the trephine bone biopsy specimen are superior to marrow aspiration cell smears for the antemortem diagnosis. Thirteen cases of amyloidosis were diagnosed from the bone biopsy specimen during a ten-year period. Amyloid was detected in only two of the corresponding aspirates. Three morphologic patterns of marrow involvement were found: vascular, focal extravascular/perivascular, and diffuse. Five (38%) of the cases were associated with multiple myeloma. An abnormal immunoglobulin was detected in the serum or urine or both in ten of 11 cases when determined. Although the bone marrow may not be the best site for the diagnosis of amyloidosis, it should not be neglected and marrow biopsies taken for other diagnostic reasons may "incidentally" reveal amyloid. Amyloidosis should be included in the list of non-primary hematologic conditions of the bone marrow in which the trephine biopsy may prove useful for diagnosis. 相似文献

9-beta-D-Arabinofuranosylguanine (araG), an analog of deoxyguanosine which is not degraded by purine nucleoside phosphorylase, has been previously shown in in vitro studies by our laboratory to be effective in purging malignant T cells from human bone marrow (1). We now describe studies in a murine model of T-cell acute lymphoblastic leukemia (ALL) in which we tested whether bone marrow, contaminated with malignant T cells and purged ex vivo with araG, could reconstitute both the lymphoid and myeloerythroid lineages in the absence of leukemic relapse. The model utilized 6C3HED tumor cells, derived from a Thy 1.2+ malignant murine T-cell line, which were shown to cause lethal leukemia in C3H/HeN mice. Intravenous injection of 10(6) 6C3HED cells resulted in 100% mortality within 18 days, with autopsy revealing tumor infiltration of multiple organs. 100% of non-leukemia bearing lethally irradiated C3H/HeN mice transplanted with syngeneic bone marrow, treated ex vivo with 100 microM of araG for 18 hours, survived > 365 days post-transplant with full lymphohematopoietic reconstitution. Evidence of araG's ability to purge bone marrow of malignant tumor cells without causing significant toxicity to normal marrow derived hematopoietic progenitor cells was documented in experiments in which 75% of lethally irradiated mice transplanted with syngeneic bone marrow, contaminated with 6C3HED tumor cells and treated ex vivo with 100 microM araG for 18 hours, survived for > 250 to > 400 days. Death in 25% of mice was secondary to infection which developed before marrow reconstitution occurred. Reconstitution of the lymphoid, myeloid, and erythroid lineages with donor cells in surviving mice was documented. The data presented indicate that araG may effectively purge bone marrow of malignant T cells without irreversible toxicity to hematopoietic stem cells. This purging regimen is recommended for consideration for clinical trials in patients with T-cell malignancies undergoing autologous bone marrow transplantation and may also be a viable option for T-cell depletion as a strategy to prevent graft-versus-host disease. 相似文献

We describe a case of a 73-year-old male with a rare T-cell lymphoma that presented deceptively as progressive hepatic failure with fever, weight loss, pancytopenia, mental confusion, splenomegaly, and no lymphadenopathy. An alcoholic history supported the diagnosis of cirrhosis, but a liver biopsy was not performed. A bone marrow biopsy was considered unremarkable. Death occurred after a course of four months. Postmortem examination showed hepatic, splenic, lymph node, and marrow infiltration by characteristically sparse, isolated, bizarre, medium-to-large sized neoplastic cells with extensive hepatic centrilobular necrosis, steatosis, and predominant splenic involvement. Immunohistochemical markers indicated a T-cell lymphoma consistent with either an alpha/beta peripheral T-cell lymphoma or a gamma/delta lymphoma. Definitive immunotyping was not available. However, the pathologic features are most consistent with a gamma/delta T-cell lymphoma. This case is an example of a rare, rapidly progressive lymphoma, which is a recognized clinical entity, easily missed, and treatable. Its diagnostic consideration must be explicitly communicated to pathologists, because the isolated or sparse tumor cells in a lymph node, liver, or bone marrow biopsy may easily be mistaken for variants of megakaryocytes or histiocytes. 相似文献

We have previously demonstrated that various subtypes of AML children respond to high-dose methylprednisolone (HDMP; 20-30 mg/kg/day) which could induce in vivo differentiation of myeloid leukemic cells to mature granulocytes. In this study we have evaluated whether apoptosis occurs in AML cells of patients treated by HDMP using morphological criteria. For light and electron microscopic examination bone marrow aspirates were obtained four days and two weeks after methylprednisolone (30 mg/kg/day) treatment from two children with newly diagnosed AML (AML-M3 and AML-M4). In both patients maturation of leukemic cells has previously been reported four days (in patient with AML-M3) and two weeks (in patient with AML-M4) after HDMP treatment. Electron microscopy revealed the characteristic ultrastructural changes of various stages of apoptosis four days after HDMP treatment in a case with AML-M3. Morphologic evidence of apoptosis induced by HDMP were also detected on Wright-stained and toluidine blue stained semithin sections of BM preparations in a patient with AML-M4 and AML-M3 respectively. These findings suggest that HDMP which could induce in vivo terminal differentiation in myeloid leukemic cells is also able to induce apoptosis in patients with AML. The possibility of HDMP-induced apoptosis should be evaluated in a larger series of patients with AML and other types of malignant tumors. 相似文献
