Abstract
Patients with autoimmune diseases (AIDs) may develop lymphoproliferative disorders (LPDs) during treatment with immunosuppressive agents (IS) such as methotrexate (MTX), biological agents, or tacrolimus. Some LPDs in patients with AIDs (AID-LPDs) regress after withdrawal of IS, and a high incidence of Epstein-Barr virus (EBV) positivity in such patients has been reported. To identify characteristics and factors predictive of the response to treatment and disease progression, we retrospectively analyzed clinical and histopathological data for 81 patients with AID-LPDs. Almost all of them (96%) had been treated with MTX. Diffuse large B cell lymphoma was the most common LPD type (61%) and seven patients (9%) had classical Hodgkin lymphoma (CHL). EBV was detected by in situ hybridization with an EBV-encoded small RNA (EBER) probe in 43% of the examined cases. In 59 patients, IS was discontinued as the initial treatment, resulting in regression of LPDs in 69% of them, and multivariate analysis showed that EBER positivity was an independent factor predictive of such regression (p = 0.022). Two-year progression-free survival (PFS) and overall survival for the patients overall were 63% and 83%, respectively. Poor PFS was associated with advanced stage (p = 0.024), worse performance status (PS, p = 0.031), CHL histology (p = 0.013), and reactivation of EBV-related antibodies (p = 0.029). In conclusion, EBV positivity demonstrated using an EBER probe is useful for prediction of successful regression after withdrawal of IS in patients with AID-LPDs. Patients with advanced stage disease, worse PS, CHL histology, or reactivation of EBV-related antibodies should be closely monitored after initial treatment.

Abstract
Tyrosine kinase inhibitors (TKI) are used for primary therapy in patients with newly diagnosed CML. However, a reliable method for optimal selection of a TKI from the viewpoint of drug sensitivity of CML cells has not been established. We have developed a FRET-based drug sensitivity test in which a CrkL-derived fluorescent biosensor efficiently quantifies the kinase activity of BCR-ABL of living cells and sensitively evaluates the inhibitory activity of a TKI against BCR-ABL. Here, we validated the utility of the FRET-based drug sensitivity test carried out at diagnosis for predicting the molecular efficacy. Sixty-two patients with newly diagnosed chronic phase CML were enrolled in this study and treated with dasatinib. Bone marrow cells at diagnosis were subjected to FRET analysis. The ΔFRET value was calculated by subtraction of FRET efficiency in the presence of dasatinib from that in the absence of dasatinib. Treatment response was evaluated every 3 months by the BCR-ABL1 International Scale. Based on the ΔFRET value and molecular response, a threshold of the ΔFRET value in the top 10% of FRET efficiency was set to 0.31. Patients with ΔFRET value ≥0.31 had significantly superior molecular responses (MMR at 6 and 9 months and both MR4 and MR4.5 at 6, 9, and 12 months) compared with the responses in patients with ΔFRET value <0.31. These results suggest that the FRET-based drug sensitivity test at diagnosis can predict early and deep molecular responses. This study is registered with UMIN Clinical Trials Registry (UMIN000006358).

Abstract
PURPOSE Dasatinib is a novel, oral, multi-targeted kinase inhibitor of breakpoint cluster region-abelson (BCR-ABL) and Src family kinases. The study investigated pharmacokinetic (PK) and pharmacodynamic (PD) analyses of dasatinib in 51 newly diagnosed, chronic phase, chronic myeloid leukemia patients. METHODS The dasatinib concentration required to inhibit 50 % of the CrkL (CT10 regulator of kinase like) phosphorylation in bone marrow CD34+ cells (half maximal (50 %) inhibitory concentration (IC50)CD34+cells) was calculated from each patient's dose-response curve using flow cytometry. PK parameters were obtained from the population pharmacokinetic analysis of dasatinib concentrations in plasma on day 28 after administration. RESULTS Early molecular responses were not significantly associated with PK or PD (IC50 CD34+cells) parameters. However, the PK/PD parameter-time above IC50 CD34+cells-significantly correlated with BCR-ABL transcript level at 3 months (correlation coefficient (CC) = -0.292, P = 0.0375) and the reduction of BCR-ABL level at 1 or 3 months (CC = -0.404, P = 0.00328 and CC = -0.356, P = 0.0104, respectively). Patients with more than 12.6 h at time above IC50 CD34+cells achieved a molecular response of 3.0 log reduction at 3 months and those more than 12.8 h achieved a deep molecular response less than 4.0 log reduction at 6 months at a significantly high rate (P = 0.013, odds ratio = 4.8 and P = 0.024, odds ratio = 4.3, respectively). CONCLUSION These results suggest that the anti-leukemic activity of dasatinib exhibits in a time-dependent manner and that exposure for more than 12.8 h at time above IC50 CD34+cells could significantly improve prognosis.

Abstract
Primary bone lymphoma (PBL) comprises less than 1% of all malignant lymphomas. Because few studies of PBL have been conducted in Japan, the characteristics of Japanese patients with PBL have not been fully elucidated. We retrospectively analyzed 17 patients diagnosed with PBL at our institution between 2001 and 2011. Median patient age was 60 years. Eleven patients had diffuse large B-cell lymphoma and 2 patients had T-cell lymphoma histology. The spine was the most frequently involved site at the time of presentation. There were 11 patients with stage IV disease and 11 patients with high or high-intermediate risk according to the International Prognostic Index (IPI). Thirteen patients achieved complete response (CR) after initial treatment. At a median follow-up of 31 months, the 3-year overall survival (OS) and progression free survival were 63.5 and 49.9%, respectively. Localized disease, low or low-intermediate IPI, and CR after initial treatment were associated with a good outcome in patients with PBL and significantly associated with a better OS. Spine involvement and T/NK-cell phenotype are more frequent in Japanese than in Caucasian patients with PBL.

Abstract
A 70-year-old woman with rheumatoid arthritis treated with methotrexate (MTX) complained of right arm weakness. On CT and MRI, tumors were found in the right frontal lobe, bilateral lungs, and left renal parenchyma. She was diagnosed as having lymphomatoid granulomatosis (LYG) grade 2 on thoracoscopic biopsy of the left lung. We discontinued MTX and treated a mass lesion in the right frontal lobe with stereotactic radiotherapy. As a result, the tumors showed a gradual reduction in size, and the patient achieved complete remission. LYG is a rare lymphoproliferative disorder, and has various clinical characteristics. We describe herein a patient with LYG grade 2 with cerebral, pulmonary, and renal lesions, who has maintained a complete remission for six months, to date, after treatment.

Abstract
Invasive fungal infection (IFI) causes morbidity and mortality among patients with hematological malignancies who receive cytotoxic chemotherapy or hematopoietic stem cell transplantation (HSCT). We evaluated the incidence and treatment outcomes of proven and probable IFI in 22 institutions between 2006 and 2008 following the recent European Organization for Research and Treatment of Cancer/Mycosis Study Group (EORTC/MSG) consensus criteria. We analyzed 2,821 patients with hematological malignancies, including 597 who had undergone HSCT; these included patients with acute leukemia (n = 697), myelodysplastic syndrome (n = 284), lymphoma (n = 1465), or multiple myeloma (n = 375). IFIs were diagnosed in 38 (1.3%) patients (18 proven and 20 probable), including 20 patients who underwent HSCT and 18 who received chemotherapy alone; these included patients with aspergillosis (n = 23), candidiasis (n = 6), mucormycosis (n = 6), trichosporonosis (n = 2), and geotrichosis (n = 1). The incidence of IFI was 5.4 % in allogeneic HSCT patients, 0.4 % in autologous HSCT patients, and 0.8 % in patients receiving chemotherapy alone. Eighteen patients with aspergillosis were diagnosed with probable pulmonary IFI as determined by computed tomography scan and positive galactomannan assay. Overall, antifungal targeted therapies resulted in successful outcomes in 60.0 % of patients. IFI-attributable mortality rate was higher in HSCT patients than in those receiving chemotherapy alone, but the difference was not statistically significant.

Abstract
A 76-year-old woman presented with vaginal bleeding and discharge in September 2009. She was admitted to our hospital because a tumor of 5 cm in diameter was found in the vagina in a nearby clinic. She was diagnosed with primary vaginal diffuse large B-cell lymphoma (DLBCL) on biopsy of the tumor because CT, MRI and FDG-PET showed no area of lymphomatous involvement other than the vagina and direct involvement into the bladder. She achieved complete response (CR) after chemotherapy followed by localized radiation therapy, but she had a relapse in the central nervous system (CNS) two months after CR. A study of 57 reported cases of primary vaginal lymphoma suggested that the most common histologic type was DLBCL, and most of patients were in a localized stage and responded well to combination of chemotherapy and radiation therapy. To date, two cases of primary vaginal lymphoma with a relapse in the CNS have been reported. We presumed that direct involvement into the bladder of vaginal lymphoma contributed to the relapse in the CNS in this case.

Abstract
MALT1, BCL10 (B-cell lymphoma 10), and API2 (apoptosis inhibitor 2)-MALT1 are key molecules in mucosa-associated lymphoid tissue (MALT) lymphomagenesis. We previously reported that MALT1 and API2-MALT1 were localized only in cytoplasm, where we suggested that both molecules were likely to be active. In the study presented here, we further examined the localization-determining region by generating various mutants and were able to demonstrate that there were nuclear export signal (NES)-containing domains in the MALT1 C-terminal region. The use of leptomycin B, an NES-specific inhibitor, demonstrated that both MALT1 and API2-MALT1 were predominantly retained in the nuclei, indicating that these molecules were shuttling between nucleus and cytoplasm in an NES-dependent manner. It was also found that MALT1 was involved in the nuclear export of BCL10, which is originally localized in both nucleus and cytoplasm. These results correlate well with the nuclear BCL10 expression pattern in both t(1;14) and t(11;18) MALT lymphomas. The nucleocytoplasmic shuttling of MALT1 and BCL10 complex may indicate that these molecules are involved not only in the nuclear factor kappaB (NF-kappaB) pathway but also in other biologic functions in lymphocytes.

Abstract
Aleukemic leukemia cutis is a rare condition characterized by the invasion of leukemic blasts into the skin before their appearance in the peripheral blood. Leukemia cutis usually occurs in patients with myeloid leukemia, especially the myelomonocytic and monocytic types of acute myeloblastic leukemia. We describe the case of a 62-year-old woman with aleukemic leukemia cutis who developed Philadelphia-positive acute leukemia 1 month after skin involvement. Leukemic cells expressed both myeloid and B-cell lineage surface markers, and monoclonal rearrangement of the immunoglobulin heavy chain was detected by Southern blot analysis. This report is the first of a case of aleukemic leukemia cutis preceding Philadelphia-positive biphenotypic leukemia.

Abstract
A 44-year-old man was referred to Hakodate Chuo Hospital because of progressive fatigue in April 2001, and was diagnosed as having adult T-cell leukemia (ATL; acute type). Complete remission was not obtained even with the application of multiple anti-leukemic agents including CHOP-V-MMV. The patient received an allogeneic bone marrow transplant from his HLA-identical, HTLV-I antibody-negative sibling donor in June 2002. The conditioning regimen consisted of cyclophosphamide, etoposide and total body irradiation. Cyclosporine A and a short course of methotrexate were given as prophylaxis for graft-versus-host disease (GVHD). Engraftment was achieved on day 16, while ATL cells were detected in the peripheral blood throughout the transplantation. ATL cells were also detected in bone marrow on day 20. Withdrawal of the immunosuppressant induced the eradication of the residual ATL cells in the peripheral blood on day 24 and in the bone marrow on day 40. Grade III of acute GVHD developed in the bowel on day 40, which lasted for over 5 months and was gradually resolved by administration of prednisolone and tacrolimus. The patient remains in complete remission 23 months after the transplantation. The clinical consequence of our case clearly shows that a graft-versus-leukemia (GVL) effect combined with graft-versus-host disease (GVHD) plays a curative role even in an early phase after bone marrow transplantation for patients with adult T-cell leukemia.

Abstract
The gastrointestinal tract is one of the common targets of acute graft-versus-host disease (GVHD), but accurate diagnosis is difficult because of the nonspecific nature of complicated diseases and the lack of diagnostic findings by conventional endoscopy. Recently, a magnifying endoscope has been developed and used for examining microstructures of the mucosa. Herein, we report the first use of a magnifying endoscope for a patient with gastrointestinal (GI) GVHD. Magnified endoscopic findings of atrophic and coalescent villi of the terminal ileum reflect histological findings of GVHD. Magnifying endoscopy of the terminal ileum may be useful for early detection and follow-up of GI GVHD.

Abstract
A 60-year-old woman was admitted to our hospital to receive treatment for relapse of biphenotypic leukemia 4 years after her initial presentation. Bone marrow examination revealed 53.5% lymphoblasts, which were classified as ALL-L2 with a normal karyotype. Lymphoblast surface markers were positive for cells of both B-cell and myeloid lineage. Immunoglobulin heavy chain and T-cell receptor gene rearrangements were investigated with PCR. Clonal rearrangement of TCR delta V delta 2-D delta 3 was detected. The same clonal rearrangement of TCR delta was found using frozen initial leukemic cells. Rather than secondary leukemia, the patient's leukemia was confirmed as relapse of the initial clone. Detection of the clonal rearrangement was also useful as a patient-specific marker for minimal residual disease.

Abstract
t(11; 18) (q21; q21) is a chromosomal aberration specific to low-grade mucosa-associated lymphoid tissue (MALT) lymphoma, and generates the chimeric product apoptosis inhibitor 2 (API2)-MALT1, which has been suggested to play an important role in MALT lymphomagenesis. However, little is known about the characteristics of API2, MALT1, and API2-MALT1 proteins. We therefore investigated the subcellular localization and stability of these products. API2 was localized in the nucleus and the cytoplasm, and MALT1 and API2-MALT1 in the cytoplasm only. Western blot analysis showed that the products of API2 and MALT1 were unstable, while the API2-MALT1 product was stable. The API2 deletion mutants at the end of the C-terminal and the MALT1 deletion mutants at the end of the N-terminal were stable compared with the full-length products. These results indicate that the domains responsible for protein instability are located in the end of the C-terminal of API2 and in that of the N-terminal of MALT1, and also that API2-MALT1 became stable because it lacks these domains. It has been suggested that NF-kappaB activation plays an important role in the tumorigenesis of MALT lymphoma. Our findings further suggest that the stabilized expression of API2-MALT1 products may continuously stimulate the NF-kappaB activating pathway, thus leading to MALT lymphomagenesis.

Abstract
The clinical course of hematopoietic stem cell transplantation (HSCT) recipients was retrospectively analyzed to determine whether carriage of methicillin-resistant Staphylococcus aureus (MRSA) is a risk factor for MRSA infection during the neutropenic period. We studied four patients in whom MRSA colonies developed before HSCT. Two patients were previously diagnosed as having MRSA infection and two were carriers of MRSA. We tried to eliminate MRSA before HSCT and succeeded in eradication in two patients. MRSA infection did not develop in one patient who received prophylactic administration of vancomycin (VCM), but MRSA-induced phlegmon developed during neutropenia in one patient who did not receive prophylaxis. Of the other two patients who had been persistently positive for MRSA, MRSA did not develop in one patient who received prophylaxis, but the another patient who did not receive prophylaxis died from MRSA-induced sepsis in the early post-transplant period. We therefore recommend that MRSA be eliminated by prophylactic administration of anti-MRSA drugs such as VCM before HSCT when patients have persistent MRSA.

Abstract
The relationship between Helicobacter pylori infection and idiopathic thrombocytopenic purpura (ITP) has been investigated in several studies. We investigated the prevalence of H. pylori infection and the clinical effects of eradication in 22 Japanese patients with chronic ITP. H. pylori infection was found in 14 (63.6%) of the patients by histologic and culture examinations of biopsy samples obtained by gastrointestinal endoscopy. H. pylori was eradicated by proton pump inhibitors and 2 kinds of antibiotics in 13 (92.9%) of the 14 patients in whom the results of treatment could be evaluated. Five (38.4%) of those 13 patients had platelet recovery (platelet count of more than 100 x 10(9)/L and an increase of more than 30 x 10(9)/L with respect to the baseline value) after eradication. The median follow-up period was 15 months. One patient who had a complete response had a partial relapse after cessation of prednisolone treatment without any evidence of H. pylori reinfection. Another patient, in whom H. pylori was not eradicated even after 2 treatment sessions, had a partial response after treatment. A screening examination for H. pylori infection may be necessary for Japanese patients with newly diagnosed ITP. Although the exact mechanism underlying platelet recovery after H. pylori eradication is not clear, the results of this study indicated that H. pylori eradication treatment is a good option for some patients with chronic ITP.

Abstract
We analysed 26 T-cell receptor (TCR) beta chain subfamilies (VB) of a patient with aplastic anaemia (AA) who underwent allogeneic bone marrow transplantation (allo-BMT). The patient developed pancytopenia at d 80. The patient's T cells were skewed in 10 of 26 TCR-VB on d 83. These TCR-VB, especially VB15, which were almost entirely CD8-positive cells, were skewed throughout her clinical course. Chimaerism analysis of the CD8-positive cells indicated that they were of recipient origin. Therefore, some immune responses induced by the recipient CD8-positive T cells had an important role in pancytopenia in AA patients after allo-BMT.

Abstract
Reverse seroconversion of hepatitis B virus (HBV) after allogeneic BMT is rare. We present a case of HBV reactivation late after allogeneic BMT which responded well to lamivudine therapy. A 35-year-old woman with CML received an allogeneic BMT. Before BMT, the patient had immunity to HBV, with serum antibodies against hepatitis B surface antigen (HBsAb), and the donor was completely negative for HBV. Four years after BMT, acute hepatitis occurred with a detectable level of HBV-DNA. Lamivudine rapidly reduced transaminase and bilirubin levels, and serum HBV-DNA decreased to negative. Retrospective analysis revealed that there had been a gradual decrease in serum HBsAb titers after BMT. Administration of lamivudine immediately after HBV replication may be more effective than vaccination of hepatitis B surface antigen-negative donors before BMT.

Abstract
t(11;18)(q21;q21) has been recognized as a characteristic chromosomal translocation in mucosa-associated lymphoid tissue (MALT)-type lymphoma, and recent studies have demonstrated that this translocation results in the chimaeric transcript of API2 (apoptosis inhibitor 2)-MALT1 (mucosa-associated lymphoid tissue lymphoma translocation gene 1). In this study, we used reverse transcription polymerase chain reaction (RT-PCR) to analyse the incidence of this fusion product in a large series of MALT lymphoma, nodal marginal zone B-cell lymphoma (nMZBCL) and extranodal diffuse large B-cell lymphoma (DLBL) cases. RT-PCR analysis revealed that 17 of the 95 (17.9%) MALT lymphomas but none of the nine nMZBCLs or 16 DLBLs had API2-MALT1 fusion transcripts. The incidence of API2-MALT1 varied among MALT lymphomas arising from different sites and was highest for pulmonary MALT lymphomas (10 out of 16 cases, 62.5%). The presence of the API2-MALT1 fusion gene was also confirmed by long and accurate (LA)-PCR with genomic DNA, and the result correlated well with that obtained with the RT-PCR assay, thus demonstrating the usefulness of LA-PCR for the detection of the API2-MALT1 fusion gene.

Abstract
At least two distinct recurrent chromosomal translocations have been implicated in the pathogenesis of MALT lymphoma. The first, t(1;14), results in the transfer of the entire Bcl10 gene to chromosome 14 wherein Bcl10 expression is inappropriately stimulated by the neighboring Ig enhancer. The second, t(11;18), results in the synthesis of a novel fusion protein, API2-MALT1. Until now, no common mechanism of action has been proposed to explain how the products of these seemingly unrelated translocations may contribute to the same malignant process. We show here that Bcl10 and MALT1 form a strong and specific complex within the cell, and that these proteins synergize in the activation of NF-kappaB. The data support a mechanism of action whereby Bcl10 mediates the oligomerization and activation of the MALT1 caspase-like domain. This subsequently activates the IKK complex through an unknown mechanism, setting in motion a cascade of events leading to NF-kappaB induction. Furthermore, the API2-MALT1 fusion protein also strongly activates NF-kappaB and shows dependence upon the same downstream signaling factors. We propose a model whereby both the Bcl10.MALT1 complex and the API2-MALT1 fusion protein activate a common downstream signaling pathway that originates with the oligomerization-dependent activation of the MALT1 caspase-like domain.

The reported regression of mucosa-associated lymphoid tissue (MALT) type gastric low-grade B-cell lymphoma following treatment for Helicobacter pylori (H. pylori) infection has not yet been comprehensively analyzed, especially in relation to the recently identified c-IAP2-MALT1 / MLT gene alteration resulting from the t(11;18)(q21;q21) chromosomal translocation found in MALT lymphoma. The relationship between MALT lymphomas and H. pylori was investigated in 30 patients who received an antibacterial treatment. Patients were followed up by means of endoscopy and biopsy. Molecular genetic analyses focused on the presence or absence of the immunoglobulin heavy chain (IgH) gene and / or MALT1 / MLT gene alteration resulting from t(11;18)(q21;q21) translocation. H. pylori was positive in 26 of the 30 patients. The overall success rate of cure of H. pylori infection was 96% (25 / 26). Thirteen patients (52%) showed complete remission (CR) of lymphoma, nine (36%) partial remission (PR), and three (12%) registered no change (NC). Statistical analysis revealed significant differences between CR and PR / NC patients in age ( < 60 or 60), in lymphoma location (single or multiple sites) and in the presence or absence of gene rearrangement before eradication (P < 0.05). Endoscopy showed a cobblestone appearance only in PR cases and polypoid features predominantly in NC cases. Two NC patients with polypoid gross appearance showed rearrangements involving either c-IAP2 or MALT1 gene in Southern blot analysis, while none of seven other resected patients with non-polypoid superficial gross appearance showed rearrangement. Gastric MALT lymphoma could be pragmatically subdivided into three groups, CR (MALT-A), PR (MALT-B), and NC (MALT-C) on the basis of the reaction to eradication of H. pylori. We speculate that MALT-A may represent an incipient neoplasm or dysplasia, MALT-B a neoplasm activated by antigenic stimulation of H. pylori, and MALT-C a lymphoma independent of H. pylori. Polypoid lesions in MALT-C were associated with c-IAP2-MALT1 / MLT gene alteration resulting from t(11;18)(q21;q21). This classification is thought to be clinically significant for deciding the most appropriate mode of treatment of MALT-type lymphoproliferative disorders.

Abstract
Recent progress in molecular analysis of low-grade B cell lymphoma has revealed that API2 at 11q21 and a novel gene, MALT1 at 18q21, are involved in t(11;18)(q21;q21), a characteristic chromosome aberration for mucosa-associated lymphoid tissue (MALT) type lymphoma. We describe here the establishment of a reverse transcription-polymerase chain reaction (RT-PCR) assay that we used to analyze 22 cases of MALT lymphoma. All five cases that were shown to possess t(11;18)(q21;q21) showed the specific amplification of API2-MALT1 chimeric transcripts. Of the remaining 17 cases for which cytogenetic data were not available, three cases demonstrated the presence of fusion transcripts, indicating that a significant percentage of MALT lymphoma cases of the present series appeared to possess t(11;18). A single fragment was observed in each of these cases, but the size varied from case to case. Sequencing analysis revealed that there are two breakpoints in API2 and three in MALT1, and that all of the fusion transcripts are in-frame. On the basis of these results, four kinds of chimeric proteins can be predicted for the present series. Thus, the RT-PCR assay used here should serve as an effective molecular tool for understanding molecular pathogenesis and the clinical significance of API2-MALT1 for MALT lymphomas.

Abstract
BACKGROUND Carcinosarcomas are comprised of carcinomatous and sarcomatous elements, and their histogenesis remains unclear. The authors examined the serum concentrations of hematopoietic growth factors and performed immunohistochemical studies on an esophageal carcinosarcoma from a patient with marked granulocytosis to determine its histopathogenesis and clonality. METHODS The authors examined the case of a 63-year-old man with a polypoid tumor of the esophagus associated with marked leukocytosis (131 x 10(9) per liter). Immunohistochemical staining of the esophageal tumor was performed using monoclonal antibodies against granulocyte-colony stimulating factor (G-CSF), keratin, epithelial membrane antigen (EMA), and vimentin. RESULTS The patient's leukocyte count was increased (124 x 10(9) per liter) on admission. Because mature granulocytes predominantly were increased despite the absence of apparent infection, the patient's serum G-CSF concentration was examined and found to be 286.0 pg/mL and to increase with time. After thoracic esophagectomy was performed, granulocyte count and serum G-CSF concentration rapidly normalized. G-CSF concentration was 50-fold higher in the tumor tissue extract than in the extract from normal esophageal tissue. Microscopic examination of the resected specimens revealed that the tumor was comprised of squamous cell carcinoma (SCC) and spindle-shaped sarcomatous elements, and transitional features were observed within these two components. Immunohistochemical examination disclosed cells that were positive for keratin and EMA in the carcinomatous element and vimentin positive cells in the sarcomatous element. However, both types of tumor cells were positive for G-CSF. CONCLUSIONS The presence of G-CSF in both SCC cells and spindle-shaped sarcomatous cells indicated that these two components originated from a single clone.
