RESUMO
OBJECTIVES: We aimed to evaluate the efficacy and safety of granulocyte-colony stimulating factor (G-CSF) prophylaxis during chemoimmunotherapy with carboplatin plus etoposide and atezolizumab in extensive-stage small cell lung cancer (ES-SCLC). METHODS: This retrospective, multicenter study enrolled ES-SCLC patients receiving carboplatin plus etoposide and atezolizumab, categorized into G-CSF and non-G-CSF groups. Demographic and disease-related data were collected. Response rates, progression-free survival (PFS), overall survival (OS), and toxicity were analyzed. RESULTS: Of 119 patients (median age: 63 years), the overall response rate (ORR) and disease control rate (DCR) were 72.3% and 81.5%, respectively. In the G-CSF group, the ORR was 76.4% compared to 60.0% in the non-G-CSF group (p = 0.33), and the DCR was 85.4% versus 70.0%, respectively (p = 0.46). Median PFS was 8.3 months (95% CI, 6.8-9.8) in the G-CSF group and 6.8 months (95% CI, 6.2-7.5) in the non-G-CSF group (p = 0.24). Median OS was 13.8 months (95% CI, 9.6-18.1) for the G-CSF group and 10.6 months (95% CI, 7.9-13.3) for the non-G-CSF group (p = 0.47). Grade 3 ≥ adverse events were similar between groups (49.4% vs. 33.3%, respectively, p = 0.12). CONCLUSION: G-CSF prophylaxis can be safely used in ES-SCLC patients undergoing carboplatin plus etoposide and atezolizumab regimen without significantly altering efficacy or increasing toxicity.
RESUMO
A multicenter, retrospective, observational study was conducted to explore effectiveness and safety of ixazomib plus lenalidomide with dexamethasone (IRd) in relapsed/refractory multiple myeloma (RRMM) patients following at least ≥ two lines of therapy. Patients' treatment responses, overall response rate, progression-free survival rate, and adverse events were recorded. Mean age of 54 patients was 66.5 ± 9.1 years. There were 20 patients (37.0%) with progression. Median progression-free survival was 13 months in patients who received a median of three therapy lines in a 7.5-month follow-up period. Overall response rate was 38.5%. Of 54 patients, 19 (40.4%) had at least one adverse event, and nine (19.1%) had an adverse event of at least grade 3 or more. Of 72 adverse events observed in 47 patients, 68% were grade 1 or 2. Treatment was not stopped in any patient due to adverse events. IRd combination therapy was effective and safe in heavily treated RRMM patients.

Introduction and Aim: Primary mediastinal B-cell lymphomas (PMBL) are aggressive B- cell lymphomas. Although the initial treatment models vary in PMBL, appropriate treatment methods are not known. We aim to show real-life data on health outcomes in adult patients with PMBL who received various type of chemoimmunotherapies in Turkey. Method: We analyzed the data of 61 patients who received treatments for PMBL from 2010 to 2020. The overall response rate (ORR), overall survival (OS) and progression-free survival (PFS) of the patients were evaluated. Results: 61 patients were observed in this study. The mean age of the study group was 38.4 ± 13.5 years. From among them, 49.2% of the patients were female (n = 30). For first-line therapy, 33 of them had received rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) regimen (54%). Twenty-five patients had received rituximab, etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin (DA-EPOCH-R) regimen. The ORR was 77%. The median OS and PFS were as follows: 25 months (95% CI: 20.4-29.4) and 13 months (95% CI: 8.6-17.3), respectively. The OS and PFS at 12 months were 91.3% and 50%, respectively. The OS and PFS at five years were 64.9% and 36.7%, respectively. Median follow-up time period was 20 months (IQR 8.5-38.5). Conclusion: R-CHOP and DA-EPOCH-R showed good results in PMBL. These remain one of the best determined systemic treatment options for first-line therapy. Also, the treatment was associated with good efficacy and tolerability.

Objectives: Patients with hematological malignancies have a high risk of mortality from coronavirus disease 2019 (COVID-19). This study aimed to investigate the impact of COVID-19 on mortality rates in patients with various hematological malignancies and to determine risk factors associated with all-cause mortality. Methods: A multicenter, observational retrospective analysis of patients with hematological malignancies infected with COVID-19 between July 2020 and December 2021 was performed. Demographic data, clinical characteristics, and laboratory parameters were recorded. Patients were grouped as non-survivors and survivors. All-cause mortality was the primary outcome of the study. Results: There were 569 patients with a median age of 59 years. Non-Hodgkin lymphoma (22.0%) and multiple myelomas (18.1%) were the two most frequent hematological malignancies. The all-cause mortality rate was 29.3%. The highest mortality rates were seen in patients with acute myeloid leukemia (44.3%), acute lymphoid leukemia (40.5%), and non-Hodgkin lymphoma (36.8%). The non-survivors were significantly older (p<0.001) and had more comorbidities (p<0.05). In addition, there were significantly more patients with low lymphocyte percentage (p<0.001), thrombocytopenia (p<0.001), and high CRP (p<0.001) in the non-survived patients. Age ≥ 65years (p=0.017), cardiac comorbidities (p=0.041), and continuation of ongoing active therapy for hematological cancer (p<0.001) were the independent risk factors for the prediction of mortality. Conclusions: In patients with hematological malignancies, coexistent COVID-19 leads to a higher mortality rate in elderly patients with more comorbidities. Acute myeloid and lymphoid leukemia and non-Hodgkin lymphoma have the highest mortality rates. Older age, cardiac diseases, and continuation of ongoing active therapy for hematological cancer are the independent risk factors for mortality in hematological malignancy patients with COVID-19.
RESUMO
Microangiopathic hemolytic anemia (MAHA) defines a group of disorders characterized by the formation of microthrombi in capillaries and arterioles and the fragmentation of erythrocytes that pass through. Cancer-related MAHA is a rare but serious condition that is encountered in patients diagnosed with a malignancy. This clinical picture is thought to be linked to certain tumor characteristics; particularly, adenocarcinoma histology, vascular invasion, and bone marrow infiltration. MAHA is most commonly associated with tumors of gastric, prostate, and breast origin. The optimal treatment is not clear; however, there is evidence for the importance of promptly starting an effective antineoplastic regimen and it was also reported that administering therapeutic plasma exchange (TPE) therapy for immunocomplex removal could be beneficial for patients with symptoms of bleeding and thrombosis. Here, we present a case that presented a picture of MAHA secondary to gastric signet-ring cell adenocarcinoma (SRCC). The clinical picture was initially evaluated as thrombotic thrombocytopenic purpura and the patient benefited significantly from the TPE treatment administered before the adenocarcinoma diagnosis was confirmed. In this period, epistaxis stopped, platelet count increased from 25 × 109 /L to 162 × 109 /L, fragmented erythrocyte rate in the peripheral smear decreased by more than 75% and other laboratory findings of hemolysis (LDH, bilirubin, etc.) significantly improved.

Objective: Castleman disease (CD) is a rare disease also known as angiofollicular lymph node hyperplasia. The two main histological subtypes are the hyaline vascular and plasma cell variants. It is further classified as unicentric CD (UCD) or multicentric CD (MCD) according to the anatomical distribution of the disease and the number of lymph nodes involved. The aim of this multicenter study was to evaluate all cases of CD identified to date in Turkey to set up a national registry to improve the early recognition, treatment, and follow-up of CD. Materials and Methods: Both adult (n=130) and pediatric (n=10) patients with lymph node or involved field biopsy results reported as CD were included in the study. Patients' demographic information, clinical and laboratory characteristics, imaging study results, treatment strategies, and clinical outcomes were evaluated retrospectively. Results: A total of 140 patients (69 male and 71 female) with a diagnosis of UCD (n=73) or MCD (n=67) were included. The mean age was 39 years in the UCD group and 47 years in the MCD group. Female patients were more common in the UCD group. The most common histological subtype was hyaline vascular for both UCD and MCD patients. Asymptomatic patients were more common in the UCD group. Anemia, elevations of acute phase reactants, and hypoalbuminemia were more common in the MCD group. The most commonly used treatment strategies for UCD were surgical excision, rituximab, and radiotherapy, respectively. All UCD patients were alive at a median of 19.5 months of follow-up. The most commonly used treatment strategies for MCD were methyl prednisolone, R-CHOP, R-CVP, and rituximab. Thirteen MCD patients had died at a median of 34 months of follow-up. Conclusion: This study is important in presenting the patient characteristics and treatment strategies for CD from Turkey, with the potential of increasing awareness about CD. Treatment data may help in making decisions, particularly in countries that do not have access to siltuximab. However, larger prospective studies are needed to make definitive conclusions.

INTRODUCTION/BACKGROUND: The emergence of novel agents targeting the B-cell receptor pathway and BCL-2 has significantly changed the therapeutic landscape of CLL. We evaluated the safety and efficacy of single-agent ibrutinib in relapsed/refractory CLL in real-world settings. PATIENTS/METHODS: A total of 200 relapsed/refractory CLL patients with a median age of 68 were included in this retrospective, multicenter, non-interventional study. Data of the study were captured from the patient charts of the participating centers. RESULTS: The median for lines of previous chemotherapy was 2 (1-6); 62 (31.8%) patients had del17p and/or p53 mutations (del17p+/p53mut). Of the study group, 146 (75%) patients achieved at least PR, while 16 (8.7%) patients discontinued ibrutinib due to TEA. The most common drug-related adverse events were neutropenia (n: 31; 17.4%) and thrombocytopenia (n: 40; 22.3%), which were ≥ grade 3 in 9 (5%) and 5 (3.9%) patients, respectively. Pneumonia (n: 42; 23.7%) was the most common nonhematologic TEA. Atrial fibrillation (n: 5; 2.8%) and bleeding (n: 11; 6.3%) were relatively rare during the study period. Within a median follow-up period of 17 (1-74) months, 42 (21%) patients died. The estimated median OS of the study cohort was 52 months. Only the response to ibrutinib (CR/PR vs. SD/PD) was significantly associated with OS. CONCLUSION: Our results indicate good safety and efficacy for single-agent ibrutinib in R/R CLL in daily practice.

PURPOSE: Pralatrexate is a new generation antifolate treatment agent used for the treatment of relapsed or refractory peripheral T-cell lymphomas. This study aims to determine the general characteristics of the patients receiving pralatrexate therapy in Turkey, contributing to the literature on the effectiveness of pralatrexate therapy in peripheral T-cell lymphomas by determining the response levels of such patients to the therapy. The study also attempts to clinically examine the major side effects observed in patients during treatment with pralatrexate. METHODS: The study included patients with peripheral T-cell lymphoma followed up in the hematology units of several hospitals in Turkey. Overall, 20 patients aged 18 and over were included in the study. RESULTS: The median age at the time of diagnosis was 58.5 years. PTCL-NOS (Peripheral T-cell lymphoma, not otherwise specified) subtype was in 40% of patients, making the PTCL-NOS the most common subtype in the study. In general, most patients were diagnosed with disease at an advanced stage. Pralatrexate therapy was given to the patients at a median treatment line of 3.5. Pralatrexate dose reduction was required in only 3 patients (15%). Response to pralatrexate therapy with partial remission (PR) and above was observed in 11 (55%) of the patients. CONCLUSION: Pralatrexate seemed to be a promising novel treatment in relapsed refractory PTCL patients. However, patients receiving pralatrexate should be followed up carefully for skin reactions, mucosal side effects, thrombocytopenia and neutropenia.

Immune Thrombocytopenia (ITP) is an autoimmune disease characterized by thrombocytopenia and skin and mucosal bleeding. In patients with an indication for treatment, corticosteroids, intravenous immunoglobulin (IVIg) and anti-D are recommended as the first line, while splenectomy, thrombopoietin receptor agonists or rituximab are recommended second line options. Approximately 10 % of adult patients with ITP fall into the chronic refractory ITP group. Therapeutic plasma exchange (TPE) has generally been tested in patients with refractory ITP, who have failed to respond to conventional treatments, in case of bleeding or prior to surgical interventions. It has been stated that elimination of the antibodies that are held responsible in the pathogenesis of the disease has an effective role in the treatment. In this article, we present the results of 17 patients, who underwent TPE for refractory ITP, together with the literature data.

BACKGROUND AND OBJECTIVES: Cast nephropathy (CN) and hyperviscosity (HV), which we encounter in plasma cell diseases, are serious clinical manifestations that increase mortality and morbidity if not managed well in the early period. Therapeutic plasma exchange (TPE) procedures based on the removal of patient plasma is a frequently preferred treatment modality. TPE is recommended at varying levels of evidence for the treatment of CN and HV in plasma cell disorders. MATERIAL AND METHODS: A total of 61 patients, 50 with multipl myeloma (MM) and 10 with Waldenström macroglobulinemia (WM), who underwent TPE for CN and HV, were included in our multicenter, and retrospective study. RESULTS: A statistically significant decrease was found in all disease-related biochemical markers, which were measured 1 week after the application of TPE added to standard medical treatment (IgG; p < 0.001, IgM; p = 0.004, IgA; p = 0.14, kappa light chain; p < 0.001, lambda light chain; p < 0.001, ß-2 microglobulin; p < 0.001, total protein; p < 0.001, albumin; p < 0.001, LDH; p = 0.02, creatine; p < 0.001, hemoglobin; p = 0.010). Clinically, all 11 patients who underwent TPE for HV responded. While a partial response (PR: 80 %) was obtained in 40 of 50 MM patients with CN, no response was obtained in 10 patients (non-response: 20 %). CONCLUSION: In conclusion, it was observed that TPE reduced all biochemical markers related to HV and CN, while making a significant contribution to clinical improvement. We believe that adding TPE to the standard treatment in this patient group will reduce mortality and morbidity in the early period and have a positive effect on survival in the long term.

OBJECTIVE: Polycythemia vera (PV) and essential thrombocythemia (ET) are chronic myeloproliferative diseases that can transform to secondary myelofibrosis (SMF). In this study, we evaluated spleen stiffness using shear-wave elastography (SWE) as a predictor of progression to SMF. METHODS: Participants were grouped as healthy volunteers (HVs), PV/ET patients, and SMF patients. Participants' spleen sizes, spleen stiffness values, bone marrow fibrosis degrees, and the other parameters were evaluated. Spleen stiffness values and spleen sizes were compared between groups. RESULTS: Of the 121 participants included in this study, 52 patients were HVs, 52 patients were PV and/or ET patients, and 17 patients were SMF patients. In terms of age and sex, there was no difference between groups. Splenic parenchymal stiffness median values by using SWE were found to be 0.82 m/s in HVs, 1.41 m/s in PV/ET patients, and 2.32 m/s in SMF patients (P < 0.001). In terms of median length of the spleen, the difference between groups was significant (P < 0.001). In addition, we found a significant positive correlation between spleen stiffness and bone marrow fibrosis degree (P < 0.001, r = 0.757). However, in multivariate analysis, there was no strong independent risk factor for spleen stiffness. CONCLUSION: In this study, we showed that measurement of spleen stiffness using SWE can distinguish SMF from PV/ET patients and HVs. Therefore, we believe that SWE may be used as a noninvasive and easily accessible method to check the fibrotic progression of bone marrow in PV and ET patients to monitor the transformation to SMF, and enables to detect fibrosis in early phase.

Hemophagocytic lymphohistiocytosis (HLH) is a rare disorder of the mononuclear phagocytic system, characterised by histiocyte and lymphocyte activation. It can be classified as primary and secondary HLH. Primary HLH usually presents in childhood, and is associated with gene mutations. Secondary HLH usually presents in adulthood, and is due to an underlying infection, autoimmune disease or malignancy. We describe a case of HLH secondary to acute hepatitis-A virus infection, which was characterised by persistent fever, pancytopenia, splenomegaly, hyperferritinemia, and hemophagocytosis observed in the bone marrow. Key Words: Hemophagocytic lymphohistiocytosis, Hepatitis-A, Mononuclear phagocytes.

Background/aim: Paroxysmal nocturnal hemoglobinuria (PNH) is a very rare clonal hematopoietic stem cell disease characterized by chronic hemolytic anemia and thrombosis. We report data from a study of the occurrence of PNH among patients with idiopathic portal vein thrombosis (PVT). Materials and methods: Patients who were followed up with the diagnosis of idiopathic PVT were enrolled into this study. Those with laboratory and/or imaging evidence of any local or systemic factor that could lead to PVT were excluded. PNH clone was examined in all patients using established FLAER methodology. Results: A total of 112 patients (42 males and 70 females), none of them had a markedly PNH clone, but 4 patients (3.6%) with confirmed tests two times had small PNH clones (size between 3.02% and 4.62%). The median ages of PNH clone (-) and PNH clone (+) patients were 42 (range; 2459) vs 39 (range; 3642) years, respectively. The median hemoglobin concentration, platelet count and leukocyte count were lower in the PNH clone (+) group than the PNH clone (-) group. Anemia, thrombocytopenia, and leukopenia were detected in all PNH clone (+) patients. In addition, the PNH clone positivity size in monocytes was higher than erythrocytes in all of 4 patients. Conclusions: PNH should be considered during differential diagnosis among patients with idiopathic PVT. Small PNH clones can be detected in PVT patients that we cannot clearly determine its relationship with PVT. We need furthermore studies to explore the potential role of this finding.

OBJECTIVE: The aim of this study was to evaluate the reproducibility of measurement of spleen stiffness at the time of the initial detection of splenomegaly, whether it is found incidentally or not, in determining the etiology of splenomegaly. METHODS: The pathologies that brought about the diffuse splenomegaly were evaluated in 3 main groups as follows: hepatoportal, myeloproliferative, and infectious causes. In addition, 17 healthy control patients were recruited. All patients were examined with acoustic radiation force impulse imaging with VTQ. RESULTS: The difference between the splenic parenchymal elasticity values in the hepatoportal group (3.27 ± 0.36 m/s), in the myeloproliferative disease group (2.98 ± 0.33 m/s), in the infectious disease group (2.44 ± 0.21 m/s), and in the control group (2.08 ± 0.19 m/s) was found to be statistically significant (P = 0.001). The intraclass correlation coefficient for shear wave velocity measurement between hepatoportal causes and myeloproliferative causes was 71.2% (95% confidence interval [CI], 54.9%-87.4%), between hepatoportal causes and infective causes was 99.7% (95% CI, 98.6%-100.0%), and between myeloproliferative causes and infective causes was 83.3% (95% CI, 68.8%-97.9%). In the same patient groups, spleen volumes were measured as 64.08 ± 9.66, 78.18 ± 18.52, and 51.57 ± 7.44 cm, respectively; in the control group, it was 26.75 ± 6.57 cm. The difference between spleen volumes was found to be statistically significant (P = 0.001). CONCLUSIONS: Distinguishing the causes of splenomegaly is important because the disorders require different management strategies. In diseases that cause splenomegaly, tissue content may change according to pathogenesis. Such changes in the spleen are mechanical properties that can be quantified by elastography.

Thrombotic thrombocytopenic purpura is a rare condition that presents with microangiopathic haemolytic anaemia, thrombocytopaenia, fever, renal impairment and neurological symptoms. Plasma exchange is a lifesaving treatment for this condition. However, some cases may be non-responsive to plasma exchange, or loss of response may occur. Treatment options for refractory cases include high-dose corticosteroids, rituximab, vincristine, cyclophosphamide, splenectomy, bortezomib and N-acetylcysteine. We present a refractory case of thrombotic thrombocytopenic purpura responding to the last of these therapies.

AIM: To investigate clinical, etiological, and prognostic features in patients with hepatocellular carcinoma. METHODS: Patients with hepatocellular carcinoma who were followed-up from 2001 to 2011 were included in the study. The diagnosis was established by histopathological and/or radiological criteria. We retrospectively reviewed clinical and laboratory data, etiology of primary liver disease, imaging characteristics and treatments. Child-Pugh and Barcelona Clinic Liver Cancer stage was determined at initial diagnosis. Kaplan-Meier survival analysis was done to find out treatment effect on survival. Risk factors for vascular invasion and overall survival were investigated by multivariate Cox regression analyses. RESULTS: Five hundred and forty-five patients with hepatocellular carcinoma were included in the study. Viral hepatitis was prevalent and 68 patients either had normal liver or were non-cirrhotic. Overall median survival was 16 (13-19) mo. Presence of extrahepatic metastasis was associated with larger tumor size (OR = 3.19, 95%CI: 1.14-10.6). Independent predictor variables of vascular invasion were AFP (OR = 2.95, 95%CI: 1.38-6.31), total tumor diameter (OR = 3.14, 95%CI: 1.01-9.77), and hepatitis B infection (OR = 5.37, 95%CI: 1.23-23.39). Liver functional reserve, tumor size/extension, AFP level and primary treatment modality were independent predictors of overall survival. Transarterial chemoembolization (HR = 0.38, 95%CI: 0.28-0.51) and radioembolization (HR = 0.36, 95%CI: 0.18-0.74) provided a comparable survival benefit in the real life setting. Surgical treatments as resection and transplantation were found to be associated with the best survival compared with loco-regional treatments (log-rank, P < 0.001). CONCLUSION: Baseline liver function, oncologic features including AFP level and primary treatment modality determines overall survival in patients with hepatocellular carcinoma.
RESUMO
BACKGROUND Chronic lymphocytic leukemia (CLL) usually expresses CD5 antigen. However, 7-20% of patients are CD5 negative. We report here a series of 19 CD5-negative B-CLL cases. MATERIAL AND METHODS We reviewed 19 consecutive CD5-negative B-CLL cases seen in our medical center from 2009 to 2015 and compared them with 105 CD5-positive B-CLL cases. The two groups were compared in terms of clinical parameters, laboratory parameters, and survival characteristics. RESULTS Lymphadenopathy was present in 31.5% of the CD5-negative group and 51.4% of the CD5-positive group (p=0.029). Splenomegaly was present in 42.1% of the CD5-negative group and 16.1% of the CD5-positive group (p=0.029). There was no difference between the groups in terms of Binet A, B, and C stages (p=0.118, p=0.051, and p=0.882, respectively). The median thrombocyte count was 144×109/L and 160×109/L in the CD5-negative and CD5-positive groups, respectively (p=0.044). There was no difference between the two groups in terms of median neutrophil count (p=0.169). The mean lymphocyte count was 43.2±4.0×10^9/L and 36.7±3.2×10^9/L in the CD5-negative and CD5-positive groups, respectively (p=0.001). There was no difference between the groups in terms of autoimmune hemolytic anemia and autoimmune thrombocytopenia. In five-year follow-up, 84.2% of CD5-negative patients and 90.5% of CD5-positive patients were alive (p=0.393). CONCLUSIONS We found more isolated splenomegaly, less lymphadenopathy, a higher lymphocyte count, and a lower thrombocyte count in the CD5-negative group. There was no difference between the groups in terms of clinical stage, autoimmune phenomena, hemoglobin and neutrophil count, and survival.

BACKGROUND: Autoimmune disorders often develop during the course of chronic lymphocytic leukemia (CLL). The aim of our study was to investigate the incidence of autoimmune complications (AIC) and serological autoantibodies, and to assess the relationship of these to patient characteristics. METHODS: We prospectively collected screenings of AIC and serological markers from a total of 192 patients. RESULTS: AIC was observed in 18 (9.4%) patients. Autoimmune hemolytic anemia (AIHA) was observed in 8 patients. Autoimmune thrombocytopenia (AITP) was observed in 3 patients. Other various types of AIC were observed in the remaining 7 patients. Serological autoantibodies were positive in 17.2% of patients with CLL. The mean age of patients with AIC was higher than the control group (p = 0.036). Patients with AIC were mostly in advanced disease stage (p = 0.004), and they had received more first-line treatments than the control group (p = 0.003). Patients with AIC had a higher mean age and more advanced disease stage than patients with positive serological autoantibodies (p = 0.020 and p = 0.009; respectively). In addition, patients with AIC had also received more first-line treatment than the patients with positive serological autoantibodies (p = 0.015). Hematologic AIC was associated with older age, advanced disease stage, and treatment. Conversely, non-hematological AIC and serological autoantibodies are generally observed in early stages. CONCLUSIONS: Our study has established a coexistence of CLL and autoimmune complications. Hematologists are usually familiar with AIHA and AITP, but less so with non-hematologic AIC. The latter complications should be carefully searched for, particularly in patients with early CLL.

Endobronchial plasmacytoma is a rare manifestation of extramedullary plasmacytoma. A 49-year-old woman with a history of multiple myeloma consulted to our pulmonary service with progressive dyspnoea and cough and abnormal chest X-ray. A lesion measuring 6 × 5 cm in size existed in anterior baseline of the right lung's lower lobe in thoracic computed tomography in addition to right bronchial narrowing and atelectasis distal in lesions. Diagnostic bronchoscopy was performed previously for the obstruction and biopsy was taken from the lesion in the right middle lobe bronchus. Endobronchial biopsies showed extensive tumour infiltration with plasmocytoid cells. Immunohistochemistry was positive CD138 and Lamda. Microscopic and immunohistochemical findings supported the diagnosis of extramedullary endobronchial plasmacytoma.
