Anti-mitochondrial antibody type 2 is a diagnostic marker of primary biliary cirrhosis and complicates myositis. Myositis with anti-mitochondrial antibody type 2 is clinically characterized by slowly progressive limb, cardiac, and respiratory muscle weakness as well as serum creatinine kinase elevations. However, there has been few cases with eye symptoms. ⋯ Magnetic resonance imaging revealed bilateral ocular muscle enlargement and abnormally high intensities in the lower limb muscles. Corticosteroid therapy improved these symptoms. Myositis with anti-mitochondrial antibody type 2 can present with eye symptoms.

A 71-year-old woman with a four-year history of chronic lymphocytic leukemia (CLL) received ibrutinib as initial treatment due to progressive anemia and thrombocytopenia. Eleven months after the start of the treatments, although her cytopenia had ameliorated, she developed classic Hodgkin lymphoma, a rare form of Richter's transformation. ⋯ In general, several clinical, genetic and molecular factors are associated with Richter's transformation. In addition, our present case suggested that ibrutinib could be a potential risk factor for Richter's transformation in CLL patients.

Case Reports
Rapid Improvement of Severe Pulmonary Hypertension Due to Scoliosis-related Restrictive Ventilatory Disorder.
Few reports have highlighted the serial changes in pulmonary hypertension during respiratory management. An 18-year-old girl with severe scoliosis was referred to our hospital for worsening dyspnea on exertion. ⋯ Her oxygenation improved rapidly under noninvasive positive pressure ventilation, although partial pressure of carbon dioxide remained >80 Torr. Transthoracic echocardiography on day 7 showed clinically significant and rapid improvement of pulmonary hypertension with a TRPG of 30 mmHg.

Case Reports
Cardiac Tamponade during Tocilizumab Therapy in a Patient with Rheumatoid Arthritis and Anti-DNA Antibody Positivity.
Drug-induced lupus (DIL) is a drug-mediated immune reaction with the same symptoms as that of lupus erythematosus. We herein report the first case of tocilizumab-induced lupus syndrome presenting with cardiac tamponade. A 65-year-old man presented with cough, exertional dyspnea, and chest pain after 2 months of tocilizumab therapy for rheumatoid arthritis. ⋯ The diagnosis of cardiac tamponade due to tocilizumab-induced lupus syndrome was made. He had no recurrence of pericardial effusion after tocilizumab discontinuation. Clinicians should be alert for lupus syndrome in patients receiving tocilizumab.

Case Reports
The Acute Onset of Autoimmune Hepatitis During Pregnancy in the Absence of Hypergammaglobulinemia and Autoantibodies.
The onset of autoimmune hepatitis (AIH) during pregnancy is rare and often poses a diagnostic challenge. A 29-year-old Japanese woman experienced epigastric pain and nausea during the third trimester of her third pregnancy. ⋯ Despite normal serum IgG concentration and absence of autoantibodies, biopsy-proven severe hepatitis with centrilobular zonal necrosis and good biochemical response to corticosteroids led to a diagnosis of AIH. Therefore, AIH should be included in the differential diagnosis of liver dysfunction during pregnancy.
