AbstractAbstract PDF
Primary ovarian angiosarcoma is very rare with only 27 cases reported so far in the medical literature. We report here on a rare case of ovarian microinvasive mucinous carcinoma that was coexistent with angiosarcoma in a 54-year-old woman. The tumor was a 26x19x10 cm-sized multilocular cystic mass with a 4x3 cm-sized solid hematoma-like nodule in the center. Microscopically, it was composed mostly of mucinous tumor of various grades from borderline to microinvasive carcinoma. The hematoma-like area turned out to be an angiosarcoma, composed of pleomorphic cells that formed slit-like spaces, spindle cells that formed short fascicles and anastomosing vascular channels with atypical endothelial cells. All these cells were positive for CD31, CD34 and factor VIII-related antigen. The patient developed peritoneal and pleural metastases, which were angiosarcoma and mucinous carcinoma, respectively. We believe this case is only the fourth example of an ovarian collision tumor of angiosarcoma and surface epithelial tumor.

AbstractAbstract PDF
Carcinoma of the ampulla of Vater is rare and its pathogenesis is unclear. The role of epigenetic changes in the APC or CDH1, in the Wnt pathway, has not been reported in ampullary carcinomas.
We performed immunohistochemistry on 73 sporadic ampullary carcinomas to identify Wnt-related molecules (APC, beta-catenin, E-cadherin, c-erbB2, cyclin D1) and examined mutations in the CTNNB1, loss of heterozygosity of 5q21, and the methylation status of the CpG island of APC and CDH1.
Thirteen tumors (17.8%) showed abnormal nuclear localization of beta-catenin; this was more prominent in the intestinal type than in the pancreaticobiliary type (p=0.01). The loss of APC correlated with the loss of beta-catenin or c-erb B2 (p<0.01). The prognosis was worse in the group with APC loss than when APC was maintained (p<0.05). There was no mutation identified in CTNNB1. Six (24%) out of 25 informative cases had 5q21 allelic loss. CpG island methylation in APC and CDH1 was detected in 33 (45.2%) and 29 (31.5%) cases, respectively.
The absence of mutations in CTNNB1 and the epigenetic alteration of APC and CDH1, might be characteristic changes in the Wnt/beta-catenin signaling pathway during the carcinogenesis of ampullary carcinomas.
