Granular Cell Tumor of Rectum: A Very Rare Entity

Granular cell tumors are predominantly benign, occurring more commonly in women, with about 10% developing in the gastrointestinal tract. Rectal location of this tumor is very rare. We herein report one such case of a 61-year-old man with granular cell tumor in the rectum who underwent endoscopic curative resection

Giant Fecalith Causing Near Intestinal Obstruction and Rectal Ischemia

Fecal impaction if left untreated can lead to the hardening of stools and the formation of fecalith. Fecaliths rarely cause serious complications and are usually managed conservatively. We present this rare case of a giant fecalith causing near obstruction in an institutionalized paraplegic patient at high risk for chronic constipation and fecal impaction. This case was also unusual for causing ischemic pressure necrosis in the rectum, thereby highlighting the possible serious complications of fecalith

Squamous Cell Papilloma of the Esophagus: A Case Series Highlighting Endoscopic and Histologic Features

Esophageal squamous papillomas are rare epithelial lesions typically discovered incidentally during EGD. Their prevalence is estimated to be less than 0.01% in the general population. We present three cases of esophageal squamous papillomas identified histologically. It may be possible to identify these lesions macroscopically. One study provided a positive predictive value of 88% for squamous papilloma utilizing the triad of exophytic growth, wart-like projections, and surface vessel crossing seen on narrow band imaging during endoscopy. The etiology is unclear. Chronic mucosal irritation from GERD or esophagitis is the prevailing theory of pathogenesis, but HPV has been detected in some lesions. The malignant potential of these lesions is considered controversial. There are documented cases demonstrating complications with squamous cell carcinoma, so we recommend removal of all esophageal squamous papillomas; however, the small absolute number of cases documented in the literature makes drawing any associations or conclusions between esophageal squamous papillomas and squamous cell carcinoma difficult. Further research is needed regarding treatment and surveillance. This case series helps contribute to the small but growing literature of this rare finding

Rectal leiomyoma, a rare entity

Rectal tumors are often encountered as an incidental finding on screening colonoscopy. As per the World Health Organization, they are categorized according to their histologic appearance. These include epithelial tumors, mesenchymal tumors and lymphomas. Of interest, in our case, are mesenchymal tumors. These are sub-classified into leiomyomas and gastrointestinal stromal tumors. Our case is a 33-year old male who was diagnosed with a rectal leiomyoma. The uncommon incidence and subsequent management of a rectal leiomyoma in a male, make this case worthy for literature review

Adenosquamous Carcinoma of the Colon

Overall, colorectal cancer is the third most commonly diagnosed cancer in both men and women, meaning that it is one of the more widely recognized preventable cancers. Instances of colorectal malignancies though are overwhelmingly attributable to adenocarcinoma. Colorectal cancers with components of squamous cell carcinoma represent a statistical anomaly. Here, we present the case of a 50-year-old male, who complained of abdominal pain and weight loss over a 3-month period of time. Biopsies from a colonoscopy ultimately revealed that this patient’s colon cancer consisted of both adenocarcinoma and squamous cell carcinoma, representing a truly exceptional pathology finding in a patient diagnosed with a colorectal cancer
