    Abstract Eosinophilic fasciitis is a disease originally proposed as "diffuse fasciitis with eosinophilia" by Shulman in 1974. The patients with this disease often have history of strenuous exercise or labor a few days to 1-2 weeks before the onset. The chief symptoms are symmetrical, full-circumference swelling and plate-like hardness of the distal limbs. This is accompanied by redness and pain in the early stages, with many cases exhibiting systemic symptoms such as fever or generalized fatigue. The lesions have been observed extending to the proximal limbs, though never on the face or fingers. En bloc biopsies from the skin to the fascia show marked fascial thickening and inflammatory cell infiltration by the lymphocytes and plasma cells. Eosinophilic infiltration is useful for the diagnosis but is only seen in the early stages of the disease. Recently, "Diagnostic criteria, severity classification, and clinical guidelines for eosinophilic fasciitis" were published. This review article discusses about eosinophilic faciitis in detail, from its pathophysiology to the treatment.

    Abstract Myocardial injury with systemic sclerosis (SSc) causes pericarditis and arrhythmia, and polymyositis-induced muscle inflammation causes myocarditis. We report a rare case of overlap syndrome (SSc and polymyositis) who presented with sudden chest pain secondary to myocardial fibrosis. Although the etiology of chest symptoms in collagen disease was difficult to identify, cardiac magnetic resonance imaging (MRI) revealed not myocarditis but myocardial fibrosis in our case. Synthetic judgement of serum brain natriuretic peptide/ troponin T levels and cardiac MRI is useful in the search for the cause of chest symptoms even in patients with collagen diseases.

    Abstract Systemic sclerosis (SSc), the focus of this review, is a generalized connective tissue disease that involves sclerotic changes in the skin and sometimes various other organ systems. Clinical outcomes have improved probably due to better management of the complications, but SSc is still considered to be incurable and diffuse cutaneous SSc carries high risk of fatality. Although the pathogenesis of SSc is still unknown, the basic mechanism appears to involve endothelial cell injury, overproduction of extracellular matrix (ECM), and aberrant immune activation. This review discusses recent studies that investigated the cellular and molecular mechanisms in the pathogenesis of SSc.

    Abstract Lupus myelitis is a rare but serious condition characterized by myelopathy in patients with systemic lupus erythematosus (SLE). Its presentation is usually acute or subacute, and it is often refractory to treatment. We reported a rare presentation of lupus myelitis in a 38-year-old Japanese woman with a 20-year history of SLE. She developed paraparesis and bladder/bowel dysfunction 6 months prior to presentation. Magnetic resonance imaging revealed atrophy of the entire thoracic spinal cord with high intensity on T1-weighted sequence. She was initially treated with intravenous pulse steroid therapy, and prednisolone (20 mg/day) was continued; mizoribine was changed to azathioprine (100 mg/day). In addition, she underwent a rehabilitation program to improve lower-extremity muscle weakness. Moreover, because of the refractory clinical condition, intravenous cyclophosphamide pulse therapy was added. Within 1 month, she could walk with a cane and had a desire to urinate and defecate. In conclusion, early and aggressive treatment improves the permanent damage of lupus myelitis.
