[Pathological characteristics in screening versus clinically-detected breast cancer].

We report pathological characteristics of screen detected breast cancers versus breast cancers diagnosed outside the official breast screening program. The breast cancer screening program was organised in the county of Haute-Vienne and a pathological record was established in the Association de dépistage des cancers du sein (ADCS 87). Three hundred and thirty three cases were recorded in 50 to 74 years-old women who had been screened (74 were interval cancers), six hundred and eighty seven in 50 to 74 years-old women without screening and three hundred and fifteen in women under 50.

[Benign mesothelioma of the uterus. Clinical and histopathological aspects and evidence of its mesothelial origin. Apropos of 1 case].

Benign mesothelioma is a rare tumor nearly always find in relation to the genital tract. We report the case of a 47-year, old woman admit in the gynecologic department for metrorragia. The tumor was composed of irregular tubules between smooth muscle cells, lined by flattened or cuboidal cells without nuclear atypia or mitoses.

MLH1 and MSH2 protein immunohistochemistry is useful for detection of hereditary non-polyposis colorectal cancer in young patients.

Aims: Hereditary non-polyposis colorectal cancer is related to germline mutations of DNA mismatch repair genes MLH1 and MSH2, which result in microsatellite instability and loss of protein expression of the corresponding mutated gene in the tumour tissue.

Methods And Results: MLH1 and MSH2 protein expression was studied by immunohistochemistry in paraffin-embedded surgical samples of 100 colorectal adenocarcinomas occurring before 50 years of age. Absence of tumour cell nuclear staining with positive internal control (normal mucosa, lymphoid follicles) was considered negative.
