Abstract

APARCERO, Miguel et al. Virtual Chromoendoscopy in the early diagnosis of squamous cell carcinoma of the anal canal. Gen [online]. 2016, vol.70, n.4, pp.131-135. ISSN 2477-975X.

The anal canal is the terminal portion of the digestive tract. The anal canal is 2.5 to 4cm in lenght. The cancer of anal canal is a relatively rare malignancy and the most frequent is the type squamous cell carcinoma, accounting for a 5 year survival of 58 %. The endoscopic evaluation of microvascular pattern of superficial lesions of the anal canal, by virtual chromoendoscopy and magnifying endoscopy, achieves the diagnosis of intraepithelial neoplasia and early squamous cell carcinoma of the anal canal. Here we report our experience in 4 patients with early squamous cell carcinoma and show the endoscopy-histopathological correlation. The early diagnosis of the disease, permit curative treatment with local resection.
