Review Case Reports
CD3- and CD4-positive plasmablastic lymphoma: a literature review of Japanese plasmablastic lymphoma cases.
Plasmablastic lymphoma (PBL) is a very rare and recently-described subtype of diffuse large B-cell lymphoma. A maxillary tumor in an 84-year-old HIV-negative Japanese-man was referred. ⋯ He was diagnosed as a plasmablastic lymphoma; radiation therapy (RT) was started, but the response to the RT was only a partial response. To our knowledge, this is the first report of a patient with PBL expressing CD3 and CD4.

Review Case Reports
Subacute longitudinal myelitis associated with Behcet's disease.
In neuro-Behcet's disease (NBD), myelitis is a rare clinical form. We report the case of a woman with NBD presenting with unsteady gait and generalized spasticity. ⋯ Longitudinal myelitis involving the entire spinal cord, as seen in our patient, has never been described before. This case suggests that NBD could be one of the important differential diagnoses of longitudinal myelitis.

Necrotizing fasciitis (NF) is a necrotizing soft tissue infection that can cause rapid local tissue destruction, necrosis and life-threatening severe sepsis. Predisposing conditions for NF include diabetes, malignancy, alcohol abuse, and chronic liver and kidney diseases. ⋯ The cardinal manifestations of NF are severe pain at onset out of proportion to local findings, hemorrhagic bullae and/or vital sign abnormality. In such cases, NF should be strongly suspected and immediate surgical intervention should be considered, along with broad-spectrum antimicrobials and general supportive measures, regardless of the findings of imaging tests.

Review Case Reports
Idiopathic portal hypertension in a patient with mixed connective tissue disease and protein C deficiency.
We report a 29-year-old woman with a 2.5 year history of mixed connective tissue disease (MCTD) who developed idiopathic portal hypertension (IPH) and thrombocytopenia as a result of hypersplenism. She had recurrent esophagogastric variceal rupture. ⋯ However, portal vein thrombosis developed after splenectomy. This was a rare case of severe complications of IPH accompanying MCTD and protein C deficiency.

Review Case Reports
Purulent pericarditis caused by the Streptococcus milleri group: a case report and review of the literature.
A 69-year-old woman with a history of diabetes mellitus presented at our emergency room with chest pain and dyspnea. A chest computed tomography revealed a pericardial effusion. Pericardiocentesis was performed; strains of the Streptococcus milleri group were detected on culture of the fluid thus obtained. ⋯ Emergency pericardial drainage was performed, after which the condition resolved without any complications. We report an extremely rare case of purulent pericarditis caused by a strain of the Streptococcus milleri group. In addition, we review 5 previously reported cases of purulent pericarditis caused by strains.
