The objective was to characterize imaging findings of benign notochordal cell tumors (BNCTs). Clinical and imaging data for 9 benign notochordal cell tumors in 7 patients were reviewed retrospectively. Conventional radiographs (n = 9), bone scintigrams (n = 2), computed tomographic images (n = 7), and magnetic resonance images (n = 8) were reviewed. Eight(More)
In the present study, we cloned and characterized a novel actin-binding molecule, designated skeletrophin, from aggregated neuroblastoma cells. The putative amino acid sequence of human skeletrophin cDNA contained a cysteine-rich zinc-finger motif which was also found in dystrophin and five ankyrin repeats. Northern blot analysis revealed that the 3.2-kb(More)
Primary ovarian angiosarcoma is extremely rare. Only 16 cases have histologically been reported to date in the literature. A case of angiosarcoma arising in the right ovary of a 46-year-old female is presented. Grossly, the resected right ovary was completely replaced by a solid tumor mass, which revealed multiple necrotic and/or hemorrhagic foci. This case(More)
Only a small number of clear cell sarcoma (CCS) cell lines have been reported, including the cell line HS-MM. In the present study, this cell line, maintained for more than 4 years since establishment, was further characterized by cytogenetic studies, fluorescence in situ hybridization (FISH) analysis, and reverse transcriptase-polymerase chain reaction(More)
BACKGROUND The line of differentiation in synovial sarcoma still remains controversial. Thus far, only a few human synovial sarcoma cell lines have been described. However, their morphologic characteristics have not been fully established. EXPERIMENTAL DESIGN We established a new synovial sarcoma cell line (HS-SY-II) from pleural effusion with lung(More)
A 60-year-old-man underwent initial resection of a rectal tumor, with a transanal approach, on December 6, 2000. The tumor was diagnosed as a gastrointestinal stromal tumor(GIST) by KIT and CD34 immunohistochemistry. In June 2003, a third recurrence in the rectum was discovered, at the same location as the initial tumor, and he was referred to our hospital.(More)
Some clinicians have argued that combining pancreatic and portomesenteric venous resection could improve the rates of long-term survival. However, whether resection of the portosplenomesenteric vein could provide an acceptable survival benefit to patients with pancreatic cancer involving the portosplenomesenteric system remains controversial. The purpose of(More)
A new human cell line, designated Ty-82, was established from the pleural effusion of a 22-year-old woman with undifferentiated thymic carcinoma. This cell line consisted of primitive cells that were positive for alpha-naphthyl butyrate esterase and acid phosphatase. The cells were shown to express epithelial membrane antigen, but were completely negative(More)
Only 13 cases of pigmented squamous cell carcinoma (SCC) have been reported in the English language literature, with most frequent development in the oral cavity and conjunctiva. However, no case of pigmented SCC of the scrotum has been reported. We report here a case of pigmented SCC that arose primarily in the scrotum of a 70-year-old man. Light(More)
