A large polyp in the ascending colon

What is the most likely diagnosis of this polyp?

  • Hyperplastic polyp

  • Sessile serrated lesion

  • Deep submucosal cancer with submucosal invasion depth > 1,000 μm

A case suspicious for carcinoma should be resected en bloc with EMR or ESD with enough submucosal layer. Because such a lesion has the potential to invade into submucosal layer. To get the precise histopathologic diagnosis including submucosal invasion or not, polypectomy should not be conducted. Polypectomy can not obtain enough submucosal tissue for pathologic diagnosis.
