Pedunculated colonic lipoma prolapsing through the anus

Rectum lipoma incarcerated in anus as a cause of abundant rectorrhagia

INTRODUCTION: Lipomas are slow growing, benign tumors of mesenchymal origin. In most cases, they are incidental findings during endoscopic examinations. Lipomas in the gastrointestinal tract are rare entities with the lowest rate of occurrence in the rectum. They are mostly asymptomatic, but if they are larger than 4 cm can cause pain, intussusception, bleeding, volvulus, prolapse and weight loss. The aim of presented case report is to demonstrate that abundant rectorrhagia can be caused by a rare entity such as rectal lipoma. CASE REPORT: We present the case of a fifty-year-old male patient with a soft-structure prolapse through the anus accompanied by extensive bleeding. After repositioning, the structure was endoscopically removed. Histopathological analysis confirmed the presence of a lipoma. CONCLUSION: Rectorrhagia can be a clinical manifestation of this rare condition - incarcerated rectal lipoma and should be considered in practice as a differential diagnosis in cases where existence of more common conditions like hemorrhoidal disease and malignant tumors is excluded.

Rectal Lipoma in an Elderly Male: A Case Report

Lipomas of the gastrointestinal tract are uncommon, benign non-epithelial tumors detected incidentally during surgery or endoscopy. Rectal lipomas are extremely rare. Patients may be asymptomatic or present with rectal bleeding, constipation, tenesmus and signs of intestinal obstruction. Preoperative diagnosis is challenging. Management consists of simple observation, endoscopic or laparoscopic removal, and open surgery. We present a case of an elderly male admitted to the Department of Surgery of a general hospital in Crete, complaining of a protruding rectal mass during defecation. CT raised the diagnostic suspicion. The mass was removed by trans-anal excision. Histopathology of the resected specimen confirmed the diagnosis. The patient had an uneventful postoperative course and was discharged home at the second postoperative day.

Colonic intussusception as a rare manifestation of colonic lipoma: Case report

Introduction: Colonic lipomas are low-risk lesions that require endoscopic or surgical management depending on their size and symptoms. However, diagnosing a lipoma­tous lesion in the colon is a difficult task, as the clinical or imaging findings point to a low prevalence of these lesions and a higher fre­quency in the female sex. The laparoscopic approach is the current method of choice as it represents fewer traumas and, therefore, a faster clinical recovery.Case presentation: 43-year-old female patient, Caucasian, from the city of Bogotá, housewife, without any medical history. She presented with acute abdominal pain associated with tarry stools. Diagnostic imaging tests were performed, finding colo-colonic intussusception, originated in a lipomatous lesion located in the transverse colon. This patient underwent an enlarged lap­aroscopic right hemicolectomy.Discussion: This case describes how colonic intussusception constitutes a preoperative complication that requires surgical management since its diagnosis considering the associated mortality rates.Conclusion: The analysis of this case is part of the scientific evidence indispensable to im­prove the diagnostic and therapeutic approach to colonic intussusception, as local and in­ternational literature have not addressed this condition sufficiently.

Spontaneous Expulsion per Rectum of a Colorectal Polyp: A Rare and Unusual Case

Colorectal polyps are growths that form on the epithelium of the colon and rectum. While their prevalence varies considerably from region to region, they are common in adults. In fact, among asymptomatic, average-risk individuals at 50 years of age, the prevalence of colorectal polyps averages roughly 10% in sigmoidoscopy studies and more than 25% in colonoscopy studies. Approximately two-thirds of all colorectal polyps are adenomatous precancerous lesions that have the potential to become malignant. Usually, they are discovered and resected during colonoscopy. The spontaneous expulsion per rectum of a colorectal polyp is exceedingly rare. Here, we report a rare and unusual case that we believe is the first of spontaneous expulsion of an adenomatous polyp during defecation. These patients should undergo colonoscopy to search for additional polyps as well as other gastrointestinal pathology.

'Ubiquitous' Tumour Elsewhere, But Uncommon in the Colon! Can We Ignore this Lesion?

Lipoma, a benign tumour of mature fat cells, can occur anywhere in the body and hence termed 'ubiquitous tumour'. But it rarely occurs in the colon and can present with complications and mimic malignancy. We present a case of descending colonic lipoma which led to a diagnostic dilemma.
