Background Recent studies have shown that traditional serrated adenoma (TSA) can be
classified into BRAF and KRAS subtypes. Here, we examined the clinicopathological and …

Aims Traditional serrated adenoma (TSA) is the least common subtype of serrated colorectal
polyp. Large protuberant lesions are easily recognised; however, the origins of TSAs are not …

Objectives Serrated lesions of the colorectum often have complex histological morphology,
and some groups include subtypes with different molecular biology. This study aimed to …

Background and Aim Superficially serrated adenoma (SuSA) is a recently proposed subtype
of colorectal serrated lesions. It is characterized by distinct clinicopathological and molecular …

Abstract Background and Aim Serrated lesions (SLs) have attracted attention as precursors
of colorectal cancer (CRC). However, their prevalence, risk factors, and clinical significance …

Background Serrated polyps are incompletely understood lesions and include serrated
sessile lesion (SSL) without or with dysplasia and traditional serrated adenoma (TSA). Aims …

Colorectal cancer (CRC) is one of the world's most common types of malignancy. The
proliferation of precancerous lesions causes this type of cancer. Two distinct pathways for …

Hyperplastic nodules (HNs) have been considered to be hyperplastic lesions among
Japanese pathologists, although they have not been recognized worldwide. Here, we …

The authors also focus on SuSAs accompanied by TSAs alone, but we should look at
tubular adenomas, villous adenomas, invasive cancers, and miscellaneous lesions as …

Superficial serrated adenoma (SuSA) is a new subtype of serrated lesions proposed in
recent years, most of which are located in the sigmoid colon or rectum, with typical mixed …
