Background: Innominate grooves (IGs) in the colon are ubiquitous structures limiting
anthemic folds. The histology of the crypts in anthemic folds is well known but the histology …

The morphological characteristics of innominate lines and grooves of the colonic mucosa
are described. There are three basic mucosal patterns: linear circumferential, network, and …

Histologic sections from patients with inflammatory bowel disease (IBD) usually exhibit
crypts with architectural distortions and branching crypts. It has been postulated that crypt …

Background/Aim: In ulcerative colitis (UC) the colonic mucosa shows, in addition to a high
number of inflammatory cells, crypts with architectural distortions, called corrupted colonic …

Aims Studying crypt branching in ulcerative colitis (UC) and in infectious colitis (IC), we
detected previously unreported crypt-associated anomalies (CAAs). The objective was to …

Aims Recently, eight novel histologic structures in colon mucosa with inflammation were
described. Here, we assessed the frequency of one of them: crypt rings in tandem (CRT), in …

Background Aberrant crypt foci of the colon are possible precursors of adenoma and cancer,
but these lesions have been studied mainly in surgical specimens from patients who already …

Aims We previously found colonic crypts with asymmetric fission bordering regenerating
ulcers in ulcerative colitis (UC). The present objective was to assess the frequency of …

Radiological—histological studies showed that the normal mucosal units of the colon are
bounded by the innominate lines. The lines are superficial indentations of the mucosa with …

Aberrant crypt foci are considered potential markers of colorectal cancer risk. The aim of this
study was to analyze a large series of human aberrant crypt foci according to frequency …
