BACKGROUND Nuclear protein in testis (NUT) midline carcinoma (NMC) is a rare, aggressive malignancy. Only two pediatric and three adult cases of pulmonary NMCs have been documented. In more than two-thirds of NMC cases, a gene fusion between NUT and BRD4 or BRD3 has been documented; other fusions are rare. CASE PRESENTATION A 36-year-old woman was(More)
The concentrations of placental transfer of halothane (H), enflurane (E), sevoflurane (S), and isoflurane (I) were measured in 46 patients during cesarean section. The mean inhalation times of H (0.5%), E (1%), S (0.8%), and I (0.6%) were 13 min 27 s, 13 min 49s, 13 min 20s, and 8 min 8s, respectively. The mean concentrations in the maternal artery (MA)(More)
We report an asymptomatic 72-year-old woman with a small, incidentally detected, pancreatic somatostatinoma. The tumor, measuring 1 cm in diameter, showed a hypervascular pattern of contrast enhancement on computed tomography, and was found angiographically to receive a blood supply from the posterior superior pancreaticoduodenal artery. The results of(More)

We report a rare case of primitive neuroectodermal tumor arising from adrenal gland in adulthood, diagnosed preoperatively as having non-functional adrenocortical adenoma. Laparoscopic adrenalectomy was performed. Immunohistological examination revealed the definite diagnosis as primitive neuroectodermal tumor of the adrenal gland. Although primitive(More)
An 11-year-old boy was diagnosed with chronic recurrent multifocal osteomyelitis (CRMO) and presented with right sacro-femoral and occipital lesions. Initially, a tumor was suspected. However, the bone biopsy showed osteomyelitis with a negative bacterial culture. Bone scintigraphy revealed inflammatory changes on multiple bone lesions. The slight elevation(More)
