Abstract

Background/Aims:
Many endoscopists in Korea lack an understanding of laterally spreading, or creeping tumors(LSTs) which characteristically grow laterally, as opposed to other polypoid lesions, and which show superficially elevated lesions. An LST is similar in color to the adjacent normal mucosa, so it is difficult to recognize, but it can be detected by chromoscopy. When it grows to over 2-3 cm in its largest diameter, it can have malignant foci. It is important not to overlook the lesion and to remove it in a timely manner.
Methods:
The authors experienced 9 cases of LSTs from Jan. 1996 to Jan. 1997. We reviewed those 9 cases clinically, endoscopically, and pathologically, and tried to establish the diagnostic and therapeutic key points. (Korean J Gastrointest Endosc 17: 615-623, 1997) (continue)
