Colitis cystica profunda of the rectum: An unexpected operative finding

An Intimate Relationship Lies Between the Appendix and the Colon: A Case Report of Colitis Cystica Profunda Post-Laparoscopic Appendectomy

Cystica profunda is a rare benign finding of mucous-filled cysts in the submucosa of the gastrointestinal tract, more commonly found in the rectum and colon. Risk factors include rectal prolapse, inflammatory bowel diseases, pelvic radiation and being post-appendectomy. We present a case of a female patient presenting with rectorrhagia, found to have sigmoidal colitis cystica profunda (CCP) six months post-appendectomy. This case is one of the few in medical literature to highlight the direct association between laparoscopic appendectomy and CCP, previously discussed in the literature as a complication post-appendectomy in the American Journal of Gastroenterology.

LEARNING POINTS

Physicians should have a high index of suspicion to rule out colitis cystica profunda (CCP) when approaching a patient with rectorrhagia following laparoscopic appendectomy.It is pivotal to make a prompt diagnosis for CCP in the context of rectorrhagia and initiate timely management.It is important to differentiate CCP from other aetiologies of lower gastrointestinal tract bleed as it is coined 'the great imitator'.

Colitis cystica profunda associated with diverticulosis and calcification mimicking colorectal carcinoma: a case report and a brief literature review

Colitis cystica profunda (CCP) is a rare, uncommon and nonneoplastic condition that can occur anywhere in gastrointestinal tract, but its main occurrence is in the rectum and sigmoid colon. It is characterized by the presence of mucin filled cysts, lined by benign epithelium, beneath the muscularis mucosae, usually confined to the submucosa, and it can clinically and radiologically mimic a neoplasm. Here we report a rare case of CCP in a patient with a 2-months history of abdominal pain and severe anemia, associated with diverticulosis. The knowledge of this entity and its differential diagnosis, in particular with the intestinal mucinous adenocarcinoma, is necessary, as it can be a clinically and histological mimic of a malignant neoplasm.

Colitis cystica profunda of the rectum with adenomatous dysplastic features: Radiologic-pathologic correlation

Colitis cystica profunda is a rare nonneoplastic condition characterized by the presence of mucus-containing cysts in the submucosa of the right colon and rectum. The etiology is unclear, with a few cases reported in the literature. The presenting symptoms and signs may mimic colorectal adenocarcinoma. We report a case of colitis cystica profunda localized in the rectum, investigated by colonoscopy, CT, MRI, and subsequently surgically treated.

Report of a case combining solitary Peutz-Jeghers polyp, colitis cystica profunda, and high-grade dysplasia of the epithelium of the colon

BACKGROUND

Colitis cystica profunda is a rare nonneoplastic disease defined by the presence of intramural cysts that contain mucus, usually situated in the rectosigmoid area, which can mimic various malignant lesions and polyps. Its etiology still remains not fully elucidated, and several mechanisms such as congenital, post-traumatic, and infectious have been implicated in the development of this rare entity.

CASE PRESENTATION

Herein, we describe a unique case of colitis cystica profunda in the setting of Peutz-Jeghers-type polyp of the sigmoid colon, associated with high-grade dysplasia of the overlying epithelium in a 48-year-old female patient, who presented to the emergency room with signs of intestinal obstruction. To the best of our insight, this is the first manifestation ever reported in the literature regarding the coexistence of solitary Peutz-Jeghers-type polyp, colitis cystica profunda, and high-grade dysplasia of the epithelium of the colon.

CONCLUSIONS

The purpose of this case report is to highlight colitis cystica profunda and its clinical significance. An uncommon nonneoplastic entity, many times masquerading as malignant lesion of the rectosigmoid area of the colon. Clinicians and pathologists should be aware of this benign condition that is found incidentally postoperatively in patients undergoing colectomies, leading to unnecessary increase of morbidity and mortality in these patients, who otherwise could have been cured with conservative treatment only.
