Abstract:
The anatomical structures of the perianal and perirectal regions are complex and prone to neoplastic and non-neoplastic lesions. Some non-neoplastic lesions may show morphological similarities with neoplastic lesions, potentially resulting in misdiagnosis and unnecessary treatment. This article focuses on the pathological diagnostic features of challenging non-neoplastic lesions in the anorectal region, including inflammatory cloacogenic polyp, solitary rectal ulcer syndrome, endometriosis of the intestinal mucosa and infectious proctitis.
