Diffuse Large B-cell Lymphoma with a Multilobated Nuclear Morphology Harboring t (14;18) (q32;q21) and t (3;22) (q27;q11): A Case Report.

A 70-year-old woman was admitted to our hospital with dyspnea. Atypical cells with multilobated nuclei were observed in the pleural effusion. Diffuse large B-cell lymphoma (DLBCL) was diagnosed based on a cell block analysis.

[Persistent Effects of Mogamulizumab on Peripheral Blood Lesions after Treatment Completion in a Patient with Refractory Sézary Syndrome-A Case Report].

A 70-year-old man who developed recurrent Stage ⅣA1 Sézary syndrome after first-line treatment received 6 cycles of mogamulizumab treatment. After mogamulizumab treatment completion, persistent effects on peripheral blood lesions were observed. Although Sézary syndrome is a relatively uncommon cutaneous lymphoma, it is important to recognize that the effects of mogamulizumab may not be limited to the treatment course and might be sustained even after treatment completion.

Anisolymphocytosis: A clue for Richter transformation.

When chronic lymphocytic leukemia progressed to Richter syndrome, the coexistence of small and large lymphocytes was observed as a bone marrow finding. We consider this finding to be a clue for the progression of chronic lymphocytic leukemia to Richter syndrome.

Cancer-related thrombotic microangiopathy and disseminated intravascular coagulation in a patient with bone marrow carcinomatosis of unknown primary origin: A case report.

Background: Cancer-related thrombotic microangiopathy (CR-TMA) is a rare type of Coombs-negative hemolytic anemia, which is caused by malignancy and has a poor prognosis.

Case: A 76-year-old female was referred to our hospital due to Coombs-negative hemolytic anemia, which was causing fatigue and dyspnea on exertion, accompanied by schistocytosis. A bone marrow examination demonstrated bone marrow carcinomatosis, and the tumor cells were morphologically suspected to be signet-ring cell carcinoma cells.

Acute myeloid leukemia post‑cytotoxic therapy following chemotherapy for thymoma: A case report.

The present study reports the case of a patient with acute myeloid leukemia post-cytotoxic therapy (AML-pCT) that developed following chemotherapy for thymoma. A 64-year-old female patient underwent surgical resection for a mediastinal tumor and was diagnosed with stage IVa thymoma. She received chemotherapy, including carboplatin/etoposide, carboplatin/paclitaxel and amrubicin monotherapy.
