Some case reports of neuroendocrine tumors (NETs) and neuroendocrine carcinoma (NEC) associated with ulcerative colitis (UC) have been published. Most NET cases are small lesions corresponding to microcarcinoids (MCs). However, published case reports have presented findings of MCs as single-case reports. Thus, the frequency of MCs is still unclear. In this study, we described the clinical and morphological features of 14 cases of UC-associated MC and estimated the frequency of MC. Consecutive patients with UC who underwent complete removal of the large intestine were assessed, and 135 patients were selected...

In patients affected by unresectable liver metastases from neuroendocrine tumor, liver transplant represents currently the only realistic chance for cure. The first attempt to establish selection criteria for liver transplant in patients affected by neuroendocrine tumor liver metastases was made by Mazzaferro and associates in 2007. We report the case of a 46-year-old man who came to our institution in 2006 with right upper quadrant abdominal pain. Diagnosis of rectal neuroendocrine tumor with bilobar liver nodules was made; the patient underwent transanal local resection...

Lower gastrointestinal (GI) neuroendocrine neoplasms (NENs) of the colon and rectum are uncommon and not traditionally associated with hereditary GI cancer syndromes. However, with widespread implementation of colorectal cancer screening programs, lower GI NENs are being identified with increasing frequency. We report the first case series of six patients with lower GI NENs who were diagnosed with hereditary GI cancer syndromes by germline testing. Two patients presented with poorly differentiated rectal neuroendocrine carcinoma (NECs) with colonic polyposis and were found to have Familial Adenomatous Polyposis and MYH-Associated Polyposis, respectively...

AIM: To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for small rectal submucosal tumors (SMTs). METHODS: Between August 2008 and March 2016, 39 patients were treated with endoscopic submucosal resection with a ligation device (ESMR-L) (n = 21) or ESD (n = 18) for small rectal SMTs in this study. Twenty-five lesions were confirmed by histological evaluation of endoscopic biopsy prior to the procedure, and 14 lesions were not evaluated by endoscopic biopsy...

The rectal tonsil is a rare polypoid lesion exclusively found in the rectum and is considered a reactive proliferation of the lymphoid tissue. Although this lesion is benign, we recommend that it should be differentiated from carcinoid or polypoid type of mucosaassociated lymphoid tissue (MALT) lymphomas, based on gross findings. In this case report, we describe a case of rectal lesions with a unique appearance in a 41-year-old man. Colonoscopy revealed two 5-mm-sized nodules located opposite from each other on the left and right sides of the lower rectum...

Carcinoid tumor is the most common neuroendocrine tumor affecting the gastrointestinal tract. The coexistence of multifocal carcinoid lesions is a well-established phenomenon. Although intubation of the terminal ileum is not routinely attempted during colonoscopy, it can occasionally reveal the presence of some incidental findings. We present a patient with known rectal carcinoid, who was found to have another carcinoid lesion in the terminal ileum during surveillance colonoscopy. The patient underwent right hemicolectomy, and no chemotherapy was required as the patient was found to have stage 1 carcinoid tumor...

PURPOSE: Primary rectal lymphoma (PRL) is the third most common cause of rectal cancer following adenocarcinoma (90-95 %) and carcinoid (5 %). The most common variant of PRL is the mucosa-associated lymphoid tissue (MALT) type. To date, no study has been able to recommend an optimal treatment algorithm for this rare disease. The aim of our study was to review the English literature on primary rectal MALT lymphoma. METHODS: A review of the English literature was conducted to identify articles describing the MALT variant of PRL...

INTRODUCTION: The very first TEM (transanal endoscopyc microsurgery) in Hungary was performed in our department by professor Attila Nagy in 1992. Up to August 2016, 1385 operation in total was performed with an average number of 60 per year., 992 operations were carried out for benign reasons and 393 cases for malignancies. We analyze the malignant cases operated by TEM in 2013. SUBJECTS AND METHODS: In 2013 we performed 121 TEM on 118 patients (in 3 cases twice)...

Primary colonic adenocarcinoma and synchronous rectal carcinoids are rare tumors. Whenever a synchronous tumor with a nonmetastatic carcinoid component is encountered, its prognosis is determined by the associate malignancy. The discovery of an asymptomatic gastrointestinal carcinoid during the operative treatment of another malignancy will usually only require resection without additional treatment and will have little effect on the prognosis of the individual. This article reports a synchronous rectal carcinoid in a patient with hepatic flexure adenocarcinoma...

OBJECTIVE: The objective of this study is to explore the clinical effect and safety of endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) for treatment of rectal carcinoids. METHODS: A retrospective analysis was conducted on 42 patients with rectal carcinoids who were hospitalized and subjected to surgical treatment in our hospital from January 2010 to November 2015. The patients were categorized into two groups based on treatment received: ESD (n = 22) and EMR (n = 20)...

AIM: In Japan, most of colorectal carcinoid tumors developed in rectum. The choice of treatment is important because surgical treatment may need to construct artificial anus. Although curative endoscopic resection (ER) is desirable from the point of quality of life, sufficient evidence of endoscopic treatment for rectal carcinoid tumors is not fully obtained. METHODS: Between April 2001 and August 2013, 46 rectal carcinoid tumors in 46 patients who underwent either with endoscopic mucosal resection with a ligation device (EMR-L) or endoscopic submucosal dissection (ESD) were analyzed retrospectively...

Tumors and tumorlike conditions of the anus and perianal region originate from the anal canal and anal margin or result from direct extension of tumors from adjacent organs. The anatomy of the anal canal is complex, and its different histologic characteristics can lead to diverse pathologic conditions. The anal canal extends from the anorectal junction to the anal verge. The World Health Organization classification of anal canal tumors includes (a) anal intraepithelial neoplasia, the precursor of squamous cell carcinoma (SCC), and (b) invasive tumors...

Bladder exstrophy is a rare malformation. Ureteral diversion, such as ureterosigmoidostomy or a neorectal bladder, has been described. When the patients reach adulthood, cancer may arise in these reconstructions. Our aim was to perform a systematic review (all languages) of the published literature on neoplasia after urinary diversion and suggested management in cases of cancer. PubMed and Cochrane library were searched for relevant articles published within the last 20 years. All identified articles were reviewed for inclusion...

Colorectal carcinomas (CRC) were initially thought to be rare in Africa including Nigeria, but recent studies have shown a reverse trend in our environment. This study is aimed to identify the clinical and pathological characteristics of CRC diagnosed between July 2006 and June 2015 in the University of Uyo Teaching Hospital, and a Private Specialist Laboratory, Uyo, Akwa Ibom State, Nigeria. All histological diagnosed cases of CRC seen in the two laboratories (University teaching and a private facility) in Uyo, Akwa-Ibom state, Nigeria during the study period were retrieved noting their bio-data, pathological and clinical variables...

We report multiple rectal carcinoid tumors in monozygotic twins who, respectively, had 42 and 36 carcinoid tumors in the lower rectum. This is the first report about carcinoid tumors in monozygotic twins. Both twins developed a similar number of rectal carcinoids with a similar distribution. Investigation of their genetic background may provide information about the origin of these tumors.
