Abstract
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 patients with infectious colitis (IC), IBD (ulcerative colitis; UC or Crohn colitis; CrC) and UC in remission (UCR). In addition, the frequency of dysplastic CRT (DCRT) in IBD-associated noninvasive neoplasia (IBDNIN) were also calculated. Methods: Colon biopsies in 578 cases were reviewed: 42 cases with IC, 280 with IBD (180 UC and 100 CrC), 100 UCR and the remaining 156, IBDNIN. Results: The proportions of CRT in IC was 16.7%, in IBD 14.3% %, in UCR 3%, and of DCRT in IBDNIN, 20%. No differences were recorded between the proportions of CRT in IC, UC and CrC. Conversely, the difference in CRT frequency between UC and UCR, and between CRT and DCRT were significant (P = 0.006, and p = 0.05, respectively). Conclusions: CRT evolved in IC and in IBD. The finding of CRT in IC strongly suggest that those characteristic crypts were shaped at the early stages of mucosal inflammation. CRT persisted in IBD with protracted inflammation but plummeted in UCR, that is when the mucosal inflammation waned. The proportion of DCRT was significantly higher than that of CRT. It is submitted that DCRT might had developed in IBDNIN using CRT as scaffolds. This is the first study in which a characteristic pathologic aberration of cryptogenesis was tracked in colon biopsies from patients with IBD and with IBD-associated neoplastic transformation
