Solitary ulcer of the rectum is no longer considered as an idiopathic or autonomous disease. It is probably due to mucosal microtraumas, the most frequent being that resulting from anterior or complete rectal prolapse. Characteristic histopathological features can easily be recognized in biopsies taken from the edges or around the ulcers. This concept leads to a policy of consistent therapeutic measures: re-education of bowel habit and as a last resort surgery, either abdominal proctopexy or postanal pelvic floor repair.

Melanoma is a highly aggressive malignancy originating from melanocytes, characterized by its potential to arise in various anatomic locations, both common and rare. The incidence of melanoma has been steadily increasing globally, with variations in clinical presentation, tumor behavior, and prognosis depending on the anatomical site involved. Understanding the diverse pathological spectrum of melanoma is critical for optimizing diagnostic and therapeutic strategies.

Purpose: Proctectomy is frequently deferred at index colectomy for ulcerative colitis due to acuity or immunosuppressive treatments. The retained rectum remains symptomatic in over 50% with associated cancer risk. Management options include index or delayed proctectomy with or without restoration of continuity or surveillance.

Ulcerative colitis is a chronic relapsing-remitting and potentially progressive form of inflammatory bowel disease in which there is extensive inflammation and mucosal damage in the colon and rectum as a result of an abnormal immune response. MV130 is a mucosal-trained immunity-based vaccine used to prevent respiratory tract infections in various clinical settings. Additionally, MV130 may induce innate immune cells that acquire anti-inflammatory properties and promote tolerance, which could have important implications for chronic inflammatory diseases such as ulcerative colitis.

Background: Inflammatory bowel disease (IBD), encompassing ulcerative colitis and Crohn's disease, is a heterogeneous chronic condition characterized by periods of relapse and remission. Ulcerative colitis involves inflammation of the colon and rectum mucosa, while Crohn's disease causes deeper, transmural inflammation affecting all four gut layers from the mouth to the anus and can lead to complications such as fistulation. IBD significantly impacts patients' physical and psychological well-being, thus reducing their quality of life (QoL).

Ulcerative colitis (UC) involves persistent inflammation in the colon and rectum, with excessive reactive oxygen species (ROS) accumulation. This ROS buildup damages colonic epithelial cells and disrupts intestinal flora, worsening disease progression. Current antioxidant therapies are limited due to their instability in the gut and lack of targeting, hindering precise intervention at the lesion site.
