We herein report a 20-year-old woman who developed eosinophilic granulomatosis with polyangiitis (EGPA) and portal vein thrombosis (PVT). EGPA was diagnosed based on the patient's history of asthma, hypereosinophilia, and mononeuritis complex. ⋯ As patients with EGPA often suffer from asthma, they can be hesitant to undergo CECT. However, if patients with EGPA show uncertain thrombocytopenia with liver dysfunction, a further evaluation using CECT is warranted to detect PVT.

Objective To investigate the pathogenesis of Philadelphia (Ph)-positive acute lymphocytic leukemia (ALL), we established a lymphoblastoid cell line. Methods Bone marrow cells from a patient with Ph-positive ALL were enriched by Ficoll-Hypaque centrifugation and cultured in medium with fetal calf serum. ⋯ Furthermore, the cells were positive for CD13 and CD33 in addition to CD19, CD22 and CD79a antigens. Conclusion This unique cell line is expected to be a valuable tool for understanding the pathogenesis of Ph-positive ALL.

Review Case Reports
Aortitis Associated with Prophylactic Short-acting Granulocyte Colony-stimulating Factor Administration: A Case Report and Review of the Literature.
We herein report an 83-year-old woman with filgrastim-associated aortitis during chemotherapy for relapsed diffuse large B-cell lymphoma. She had been treated with filgrastim as a prophylaxis for neutropenia during the fourth cycle of chemotherapy from day 9 to 18. On day 21, she developed a fever. ⋯ The fever abated with non-steroidal anti-inflammatory drug treatment. A literature review identified a small number of aortitis cases all caused by prophylactic use of granulocyte colony-stimulating factors (G-CSFs), among which short-acting filgrastim was rarely encountered. The present and previous findings imply a possible relationship between aortitis and prophylactic G-CSF usage.

Review Case Reports
Pulmonary Nodular Lymphoid Hyperplasia Evaluated with Bronchoalveolar Lavage Fluid Findings: A Case Report and Review of the Literature on Japanese Patients.
Pulmonary nodular lymphoid hyperplasia (PNLH) is a very rare disease, and it is difficult to diagnose PNLH and distinguish it from mucosa-associated lymphoid tissue (MALT) lymphoma. In addition, information on bronchoalveolar lavage fluid (BALF) analyses is lacking. ⋯ The BALF showed an increase in B-cell marker-positive lymphocytes, normal patterns of B-cell clonality, mucosa-associated lymphoid tissue 1 gene, and immunoglobulin heavy chain at 14q32 translocations. We also reviewed Japanese cases of PNLH described in Japanese or English to explore the characteristics of such cases.
