Lymphomatoid granulomatosis (LG) is Epstein-Barr virus associated and aggressive B cell lymphoproliferative disease. The most common sites of involvement are lungs, skin, kidneys, liver and central nervous system. The clinical presentation of pulmonary LG may mimic infectious diseases, malignancies or vasculitis. While treatment approach of low grade disease is watch and wait, patients with advanced stage require aggressive treatment with chemotherapy. Patients with hematological malignancy as well as solid tumors are at increased risk of venous thromboembolic events (VTE). We reported here in a case of pulmonary LG who was complicated with VTE during treatment with chemo-immunotherapy After 4 cycles of R-CHOP, she achieved complete remission for LG and was followed up without relapse for 2 years. She was anticoagulated with Low-Molecular-Weight Heparin (LMWH) during chemotherapy period, and the thrombus improved over the next several weeks. While on this paper written, patient completed her pregnancy successfully under anticoagulation prophylaxis.

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.

Objective: The aim of this study was to examine the effect of coronavirus disease 2019 (COVID-19) on the malignancy-related clinical course and overall survival, and to determine the factors affecting mortality. Methods: This retrospective study included 77 patients with hematological cancer and COVID-19. Patients were sub-grouped for analysis as survivors and non-survivors. Results: COVID-19 was seen more frequently in myeloproliferative neoplasms (MPN), non-Hodgkin lymphoma (NHL) and multiple myeloma (MM) patients. Mortality rate due to COVID-19 was 20.8%. No statistically significant difference was determined between the survivor and non-survivor groups with respect to age and gender, presence of any comorbidity, leukocyte, neutrophil, lymphocyte, and monocyte values. Platelet count and hemoglobin count were significantly lower in the group with mortality than in the group with recovery. Conclusion: It should be kept in mind that low hemoglobin and platelet levels contribute to mortality. In addition, it is important to protect patients with hematological cancer from COVID-19 and undertake effective vaccination due to its mortal course.

INTRODUCTION: Synchronous detection of multiple myeloma and acute myeloid leukemia in a single patient is a rare coincidence. Treatment of these patients is still unclear, mostly based on acute myeloid leukemia strategies combined with bortezomib. CASE REPORT: A 72-year-old male with no medical history was investigated for pancytopenia. On medical examination, he was complicated with a wide and severe skin infection on arm. On examination of bone marrow aspirate, 25% myeloblasts infiltration and additional 10% plasma cells were seen. Acute myeloid leukemia was diagnosed and plasma cell proliferation was attributed to reactive plasmacytosis due to skin infection. However, flowcytometric studies and immunohistochemical examination revealed two different cell populations with 30-40% atypical plasma cells and >20% myeloblasts. Serum M-protein detected by serum electrophoresis test and immunofixation test revealed a monoclonal IgG lambda band. He was diagnosed with concurrent acute myeloid leukemia and multiple myeloma without history of chemotherapy.Management and outcome: The patient was initially treated with bortezomib and dexamethasone for the myeloma. Subsequently, azacitidine was administered subcutaneously for the acute myeloid leukemia treatment. The tru-cut biopsy of the lesion on his arm revealed suppurative inflammatory findings and no malign cells detected. Antibiotherapy was started according to susceptibility. He expired after three months of survival. DISCUSSION: The synchronous occurrence of these two different clonal hematological malignancies is rare in hematology practice. Patient-based prospective studies and case series are needed to guide diagnosis and treatment strategies. Furthermore, this report highlights the importance of ruling out reactive plasmacytosis in patients with hematological malignancy who developed severe infections.
