“…In another study by Koinuma et al[69], magnifying endoscopy was demonstrated as a useful tool for distinguishing neoplastic from non-neoplastic lesions, reducing the amount of biopsies needed; however, the efficacy of this technique for studying the underlying inflammatory process was shown to be limited by the presence of multiple PPs[65]. In another study, 165 patients with long-standing UC were divided and randomized for endoscopic surveillance by means of either conventional endoscopy (with biopsies every 10 cm) or chromo-endoscopy (with 0.1% methylene blue); there were two false-negative results that were not identified by the chromo-endoscopy procedure, for which non-targeted biopsies from colons with multiple PP proved to contain dysplasia[70].…”

Pseudopolyps are a well described entity in the literature and even though the exact pathogenesis of their formation is not completely understood, they are considered non-neoplastic lesions originating from the mucosa after repeated periods of inflammation and ulceration associated with excessive healing processes. Their occurrence is less common in Crohn's disease than in ulcerative colitis, and their overall prevalence ranges from 4% to 74%; moreover, they are found more often in colon but have been detected in other parts of the gastrointestinal tract as well. When their size exceeds the arbitrary point of 1.5 cm, they are classified as giant pseudopolyps. Clinical evaluation should differentiate the pseudopolyps from other polypoid lesions, such as the dysplasia-associated mass or lesion, but this situation represents an ongoing clinical challenge. Pseudopolyps can provoke complications such as bleeding or obstruction, and their management includes medical therapy, endoscopy and surgery; however, no consensus exists about the optimal treatment approach. Patients with pseudopolyps are considered at intermediate risk for colorectal cancer and regular endoscopic monitoring is recommended. Through a review of the literature, we provide here a proposed classification of the characteristics of pseudopolyps.

Organising pneumonia is defined histopathologically by intra-alveolar buds of granulation tissue, consisting of intermixed myofibroblasts and connective tissue. Although nonspecific, this histopathological pattern, together with characteristic clinical and imaging features, defines cryptogenic organising pneumonia when no cause or peculiar underlying context is found. Rapid clinical and imaging improvement is obtained with corticosteroid treatment, but relapses are common after stopping treatment.

Only two cases of rectal giant inflammatory polyposis with ulcerative colitis have been reported in the English literature and both concern children. This is the first report of a case of localized giant inflammatory polyposis of the rectum in an adult with indeterminate colitis. A 71-year-old man underwent sigmoidectomy due to stenosis of the sigmoid colon. Final histological diagnosis was indeterminate colitis. Three years following the first operation, a rectal tumor with giant polyposis was observed, and abdominoperineal resection was performed. Macroscopic and microscopic examination indicated a localized giant inflammatory polyposis of the rectum.
