“…Minamoto et al reported that superficialtype adenocarcinomas classified as de novo carcinomas may arise from very small superficial-type adenomas. 36) In the present study, drs mRNA expression was down-regulated in 2 of 8 superficial carcinomas without any adeno- matous component. These cases may be carcinomas arising from flat adenoma in the course of the adenoma-carcinoma sequence.…”

“…[4][5][6][7] Flat colorectal adenomas have previously been detected in individuals with and without hereditary colorectal cancer predisposition. [8][9][10] Flat colorectal adenomas are described as pre-malignant lesions with subtle morphological differentiation limited to the submucosa and no or limited protrusion into the colorectal lumen. 11 The malignant properties are evident during histological examination and little is known about the genetic changes that predispose to the development of the flat, rather than exophytic, appearance.…”

“…Muitos autores recomendam o uso da CE com o objetivo de aumentar a sensibilidade da colonoscopia de resolução convencional na detecção desses tipos de lesão (1,4,5,6,7,8,9,10,11,12,15) .…”

“…Com o objetivo de otimizar a detecção de lesões menores ou planas localizadas no cólon, diversos autores passaram a utilizar corantes durante a realização da colonoscopia convencional (1,4,5,6,7,8,9,10,11,12,15) . O índigo-carmim (IC) é corante habitualmente instilado sobre a mucosa colorretal, objetivando melhor visualizar lesão já detectada à colonoscopia convencional, como resultado de sua deposição sobre os orifícios que correspondem às aberturas mucosas das glândulas intestinais (Lieberkühn), levando dessa forma, a melhor definição do relevo mucoso intestinal -cromoendoscopia (CE) de contraste.…”
