RESUMO
Primary papillary serous carcinoma of the peritoneum(PPSCP) is vere rare. It has been suggested that PPSCP derives from embryonal coelomic epithelium with m llerian ducts potential. PPSCP can develop from a single or multicentric focus. The clinical and histologic disease entities are similar to those of primary papillary serous carcinoma of the ovary, but PPSCP involves the ovarian surface only minimally(microscopic disease) or spares the ovaries entirely. We have experienced a case of primary papillary serous carcinoma of the peritoneum and report this case with brief review of the concerned literature.

OBJECTIVE: To determine the value of sonographic nuchal translucency measurement for the detection of chromosomal abnormalities in high risk pregnancies. METHOD: The feasibility of nuchal translucency was tested in a prospective study of 1260 pregnancies at 10- 13 weeks' gestation. RESULTS: The nuchal translucency of 3 mm or greater was identified in 41 fetuses (3.2%), 19 of whom proved subsequently by either amniocentesis or postnatal follow-up have chromosomal abnormalities. The sensitivity of nuchal translucency for chromosomal abnormalities was 82.6% (19 of 23 cases), the positive predictive value of nuchal translucency for chromosomal abnormalities detection was 46.3% (19 of 41 cases). CONCLUSION: The observed sensitivity, false-positive rate and predictive value suggest that sonographic nuchal translucency should be undertaken at 10 to 13 weeks of gestation.
