Despite numerous attempts to uncover the mechanism of other iatrogenic immunodeficiency-associated lymphoproliferative diseases (OIIA-LPDs), this mechanism remains poorly understood, especially in rheumatoid arthritis (RA) patients. We analyzed the data on 23 patients with LPDs and RA. Patients were categorized into three groups according to whether they(More)
Although the introduction of bortezomib and immunomodulatory drugs has led to improved outcomes in patients with multiple myeloma, the disease remains incurable. In an effort to identify more potent and well-tolerated agents for myeloma, we have previously reported that 1'-acetoxychavicol acetate (ACA), a natural condiment from South-East Asia, induces(More)
Primary cardiac lymphoma is extremely rare and is associated with a poor prognosis. In most cases, cardiac involvement occurs as a late symptom and the diagnosis is thus delayed. We herein report a 35-year-old woman with cardiac diffuse large B-cell lymphoma (DLBCL) with breast infiltration. The patient was admitted to our hospital based on an initial(More)
Recently, attention has been focused on methotrexate-induced lymphoproliferative disease (MTX-LPD), and atypical phenotypes are occasionally documented. We encountered two patients with rheumatoid arthritis (RA) who were diagnosed with non-specific LPD (LPD-nos). Biopsy samples were not obtained during the initial examination when the LPD development was(More)
Thrombopoietin receptor (TPO-R) agonists have been shown to be effective in refractory chronic immune thrombocytopenia (ITP); however, their efficacy in patients under critical care is not known. We report the case of a female patient with a newly diagnosed ITP who experienced severe bleeding from an external wound. The patient was administered the standard(More)
