Aggressive angiomyxoma (AA) is a rare mesenchymal tumor that preferentially involves the pelvic and perineal regions, and is characterized by frequent local recurrences. We describe here a case of large AA in a 31-year-old woman. The patient was admitted to our hospital with a mass in the perineal region, associated with severe menstrual pain. Although her(More)
Primary laryngeal angiosarcoma (LA) is quite rare with only 13 cases reported in English literature to date. A case of LA after radiation therapy for tuberculosis and squamous cell carcinoma is reported. A 70-year-old woman had a history of radiation therapy for left cervical tuberculosis at the age of 28. At 60 years of age a squamous cell carcinoma of the(More)
We herein report a rare case of double primary liver cancer, consisting of intrahepatic cholangiocarcinoma (ICC) and hepatocellular carcinoma (HCC). A 67-year-old Japanese man with hepatitis C virus-related liver cirrhosis was diagnosed with multiple HCC in S7 and S8 of the liver. We performed a hepatic resection of S7 and S8. The liver tumors in S7 and S8(More)
To assist physicians in recognizing the potentially fatal onset of symptoms in cases of fulminant bacterial infection, we analyzed 11 autopsy cases of such infection (four caused by Streptococcus pneumoniae, four by S. pyogenes, one by S. dysgalactiae subsp. equisimilis, one by Staphylococcus aureus, and one by Vibrio vulnificus). Clinicohistopathologic(More)
Myoepithelial neoplasm mainly occurs in the salivary glands and breasts and is extremely rare in the lung. To our knowledge, this report describes the first documented case of a myoepithelial carcinoma present in the lung. The tumor derived from the right main bronchial submucosa and exhibited a dual epithelial and smooth muscular phenotype by(More)
BACKGROUND The increase of glucose transport is a distinguishing marker of tumor cells. We hypothesized that a hypopharyngeal carcinoma, characterized by high frequency of lymph node spread or distant metastasis, was associated with glucose transporter 1 (Glut 1) overexpression. MATERIALS AND METHODS We investigated the incidence of Glut1 expression by(More)
BACKGROUND Cytomegalovirus (CMV) is the most significant infectious cause of congenital anomalies of the central nervous system caused by intrauterine infection in humans. The timing of infection and the susceptibility of cells in early gestational stages are not well understood. In this study we investigated the susceptibility of embryonic stem (ES) cells(More)
The autopsy case of a 3-year 6-month-old boy with chordoma arising in the sacrococcygeal region is presented. The primary lesion of the sacrococcygeal area was unresectable and lung metastasis was detected. He was treated with multi-agent systemic chemotherapy and radiation therapy, but the tumor was less responsive to these therapies. He died about one(More)
Intravenous leiomyomatosis (IVL) is a rare benign tumor. The clinical behavior can be life-threatening due to extension through the pelvic veins. A 70-year-old woman was referred to our hospital with IVL originating from a uterine leiomyoma and extending to the inferior vena cava. The patient was diagnosed on the basis of the results of various studies, and(More)
