rectal carcinoid

Molham Abdulsamad, Naeem Abbas, Bhavna Balar
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...

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...

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...

BACKGROUND AND OBJECTIVES: Transanal minimally invasive surgery (TAMIS) has emerged as an alternative to transanal endoscopic microsurgery (TEM). The authors report their experience with TAMIS for the treatment of mid and high rectal tumors. METHODS: From November 2011 through May 2016, 31 patients (21 females, 68%), with a median age of 65 years who underwent single-port TAMIS were prospectively enrolled. Mean distance from the anal verge of the rectal tumors was 9...

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.

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) has been a valuable treatment of choice for rectal carcinoid tumors that are endoscopically treatable because of its satisfactory resection rate and low recurrence rate. For treatment of small rectal carcinoids, endoscopic mucosal resection (EMR) is more often chosen by endoscopists because of its safety and time efficiency. We applied circumferential incision and endoscopic mucosal resection (CI-EMR), which is a modification of EMR, to treat rectal carcinoid tumors and compared their efficacy and safety...

The present case study presented a 59-year-old man with a 7 mm submucosal tumor in the lower rectum and swelling in a 7 mm lateral lymph node (the obturator lymph node). No swelling of the lymph nodes within the mesorectum was observed. The patient underwent laparoscopic intersphincteric resection with left side lateral lymphadenectomy. At the pathological examination, the patient was diagnosed with a rectal neuroendocrine tumor (Grade 1; carcinoid), which had invaded the perirectal tissues and exhibited lateral lymph node metastasis; however, mesorectal lymph node metastasis was not observed, therefore, the definitive diagnosis was rectal carcinoid with skip metastasis to the lateral lymph node...

A 77-year-old woman was admitted to our hospital with the chief complaint of chest pain. CT showed a liver tumor that was 45 mm in diameter. A colonoscopic examination revealed a submucosal tumor in the lower rectum, which was diagnosed by histopathology as a neuroendocrine tumor (NET), grade 2. Liver biopsy confirmed the diagnosis of a liver metastasis from a rectal carcinoid. Considering surgical stress and possible complications, we first performed hepatectomy followed by low anterior rectal resection in a two-stage operation...

BACKGROUND: Local excision of small (<10 mm) rectal carcinoids is a standard treatment. Actual patterns of care and outcomes are understudied because of the rarity of this tumor. METHODS: Surveillance, Epidemiology, and End Results database (1988 to 2012) was interrogated for rectal carcinoid patients. Chi-square testing and Kaplan-Meier survival analysis were used to compare survival outcomes. RESULTS: Of all, 11,329 patients were identified-9,605 with only localized disease...
