The association between IgG4 dysregulation and inflammatory pseudotumor (IPT) was first reported in sclerosing pancreatitis. Recently, we described IPTs of the liver and breast, into both of which many IgG4-positive plasma cells had infiltrated. In this study, we examined the clinical and histological features of 9 cases of IPT (histologically corresponding(More)
Chronic sclerosing sialadenitis (CSS) is a cryptogenic tumor-like condition of the salivary gland(s). While immune-mediated processes are suspected in its pathogenesis, and CSS is occasionally reported to be associated with sclerosing pancreatitis, an IgG4-related disease, the exact immunopathologic processes of CSS remain speculative. In this study, we(More)
The association between IgG4 and inflammatory pseudotumor was first reported with regard to pancreatic pseudotumor, which is well known as sclerosing pancreatitis or autoimmune pancreatitis. In addition, there is increasing evidence that IgG4 is also involved in inflammatory pseudotumor of the extrapancreatic tissue. In this report, we present a case of(More)
Desmoid tumors develop in the muscle or aponeurosis, but rarely in the chest wall. We report a patient with desmoid tumor in the chest wall. A 30-year-old female visited our hospital due to an abnormal shadow in the chest detected at a health examination. No definite diagnosis could be made by chest CT, MRI, or Ga scintigraphy, and finally a biopsy(More)
BACKGROUND AND OBJECTIVE Although midazolam is commonly given orally to infants and small children for premedication, the taste is sometimes unacceptable even when mixed with syrup. We tested the efficacy and safety of oral fentanyl compared with oral midazolam in a randomized open-label study. METHODS Fifty-one children, aged 12-107 months and weighing(More)
We report the case of a 67-year-old man with metastatic papillary renal cell carcinoma (RCC) who developed bloody sputum after the administration of sunitinib. Chest computed tomography revealed diffuse ground-glass opacity lesions, and bloody bronchoalveolar lavage fluid was obtained by flexible bronchoscopy. The abnormal shadows promptly regressed after(More)
The ciliated hepatic foregut cyst (CHFC) is a rare lesion that may arise from remnants of the embryonic foregut. Its wall is lined by pseudostratified ciliated columnar epithelium, and is characterized by the presence of bundles of smooth muscle. Herein is presented two cases of ciliated hepatic cyst without smooth muscle layer. One case was an incidental(More)
Patients with neurolymphomatosis show lymphoma cells within the peripheral nerves, nerve root/plexus, or cranial nerves. However, most neurolymphomatosis patients show lymphomatous infiltration not only in the peripheral nervous system (PNS), but also in the meninges, Virchow-Robin space, and brain parenchyma. Here, we report a 74-year-old woman with(More)
