[Intramuscular capillary-venous angioma extending into the infratemporal fossa. Apropos of a case].

A rapidly growing tumor in the temporal area extended into the infratemporal fossa. Imaging findings favored a hypervascularized meningo-sarcoma type extracranial tumor, but the pathology report on the surgical specimen confirmed the diagnosis of capillaro-venous angioma. The therapeutic approach was preoperative hyperselective embolization then access via the temporal and infra-temporal fossa for simple tumor exeresis.

Expression of p53 in oesophageal squamous epithelium from surgical specimens resected for squamous cell carcinoma of the oesophagus, with special reference to uninvolved mucosa.

Accumulation of p53 protein has been considered an intermediate biomarker in multistage oesophageal carcinogenesis. The aim of the present study was to investigate p53 expression by immunohistochemistry in 13 thoroughly sampled oesophagectomy specimens from a geographical area with a high oesophageal cancer incidence (Basse Normandie, France). Expression of p53 was looked for in tissue samples of cancer, intraepithelial neoplasia, and uninvolved mucosa.

DNA cytometric abnormalities in human esophageal squamous intraepithelial and invasive carcinomas.

DNA ploidy abnormalities of 21 archival human esophageal intraepithelial neoplasia samples were assessed, using image cytometry of deparaffinized samples, with reference to invasive squamous cell carcinoma and corresponding uninvolved squamous epithelium. Cytometric parameters investigated were proportion of G0G1 aneuploid cell population, histogram typing, proportion of G0G1 diploid nuclei, coefficient of variation, mean DNA content, crude 5c exceeding proportion, 2c deviation index, malignancy index and grade, and entropy. The distributions of the above parameters were compared using the paired t test and Fisher's exact test.

Pathologic assessment of tumor regression after preoperative chemoradiotherapy of esophageal carcinoma. Clinicopathologic correlations.

Background: The benefits of preoperative chemotherapy and radiation for esophageal carcinoma are under investigation. A pilot study was undertaken to determine if pathologic assessment of tumor regression correlated with disease free survival.

Methods: Ninety-three resected specimens from patients treated with cis-dichloro-diamino cisplatin and irradiation before surgery were examined on semiserial sections.
