[Resection of a laterally spreading tumor by strip biopsy].
A male white patient 58 years-old was submitted to colonoscopy for follow-up of surgical resection of an advanced colorectal carcinoma 33 months ago. Small polyps were observed in the colons and histopathological examination proved to be tubular adenomas with moderate dysplasia. At the hepatic flexure of the transverse colon a large flat-elevated laterally spreading tumor measuring 2.5 cm in diameter was observed. After spraying of methilene-blue 0.1% the margins of the lesion were demarcated and following saline injection under the lesion it was completely resected in one single procedure. Histologically, the lesion was diagnosed as intramucosal adenocarcinoma.
