Abstract
Neuroendocrine carcinoma in Barrett's esophagus is rare and its developmental mechanisms remain unclear. Neuroendocrine carcinoma arising in Barrett's esophagus with adenocarcinoma was detected at an early stage and resected by endoscopic submucosal dissection. Detailed pathological examination revealed that the neuroendocrine carcinoma originated via differentiation of the preexisting adenocarcinoma. A 79-year-old man presented with a flat protruding lesion in the esophagogastric junction. Esophagogastroduodenoscopy revealed a red flat 10-mm protruding lesion in the Barrett's epithelium and a shallow depression at the distal end. Narrow band imaging with magnification showed that the blood vessels in the protrusion were dilated and meandered irregularly, while those in the depression were small and did not form a network; the blood vessels were missing in some parts of the depression. Well-differentiated adenocarcinoma was diagnosed after analysis of the biopsy specimen of the protrusion, and endoscopic submucosal dissection was performed. The pathological diagnosis was neuroendocrine carcinoma with an adenocarcinoma component.

Neuroendocrine neoplasms of gastrointestinal tract and secondary primary synchronous tumors: A systematic review of case reports. Casualty or causality? PLoS One 2019; 14:e0216647. [PMID: 31086397 PMCID: PMC6516644 DOI: 10.1371/journal.pone.0216647] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2018] [Accepted: 04/26/2019] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Neuroendocrine neoplasms (NENs) can arise in most of the epithelial organs of the body and are not a rare condition in the gastrointestinal tract (GIT). The presence of NENs in GIT associated with other secondary primary malignancies (SPM) has been considered an exotic event. This study aims to describe the case reports of NENs accompanied by synchronous primary tumors. METHODS AND FINDINGS We performed a systematic literature search of the databases Scopus, PubMed, Scielo and LILACS to identify case reports that described the presence of NENs in GIT with SPM. 78 case reports were included. The mean of age of the cases was 60.2 years. 60% were male. 95.4% were NENs G1. 17 cases of NENs had metastasis. 80% of SPM were recognized in the GIT (36% in stomach, 27% in large intestine, 11.2% in small intestine, and 5.6% in esophagus). The most common type of SPM was adenocarcinoma (49.4%), followed by GIST (13.5%), other NENs in different GIT segment (7.9%), lymphoma (6.8%), and squamous cell carcinoma (4.5%). The most common tumor in GIT was adenocarcinoma (97.6%) and the presence of adenocarcinoma in the same segment of GIT was found in 68.4% of the cases. Association between adenocarcinomas and NENs in GIT (p:<0.0001) and adenocarcinoma and tumor in the same segment of GIT location were observed (p<0.001). CONCLUSION These results demonstrate that NENs with SPM are not a rare condition. Several theories have been proposed to explain this association; one of these is the ability of NENs to generate synchronous tumors by autocrine and paracrine effect. We observed an association between adenocarcinomas and NENs in the same segment of GIT.

Abstract
Background An esophageal neuroendocrine carcinoma arising in Barrett’s esophagus is extremely rare. Here, we report a case of an esophageal neuroendocrine carcinoma with a well-differentiated adenocarcinoma component arising in Barrett’s esophagus and review the literature. Case presentation A 71-year-old man with no symptoms was admitted to our hospital because of the detection of an esophagogastric junction tumor on regular upper endoscopy screening. Endoscopy revealed a sliding hiatal hernia and an approximately 10 mm elevated mass at the esophagogastric junction. Biopsy showed a moderately differentiated tubular adenocarcinoma. Computed tomography did not indicate lymph node metastasis or distant metastasis. Proximal gastrectomy with D1 lymph node dissection was performed along with jejunal interposition. On immunohistochemical staining, the tumor was positive for chromogranin A and synaptophysin. Ki-67 was positive in 40% of the tumor cells. The histological diagnosis was a neuroendocrine carcinoma with a well-differentiated adenocarcinoma component arising in Barrett’s esophagus. The postoperative course was good, and the patient was discharged on the twentieth postoperative day. He has remained free of the disease at 36 months postoperatively. Conclusions Barrett’s esophagus may be related to the development of a neuroendocrine carcinoma.

Abstract
The authors describe a case of small cell carcinoma of the esophagus that was treated by concurrent chemoradiotherapy. Both the esophageal tumor and the regional lymph node metastases disappeared after this treatment. The patient is alive and disease free after more than five years. Primary small cell carcinoma of the esophagus is a rare and aggressive neoplasm with a very poor prognosis, and the treatment modality is controversial. This case illustrates the possibility of treating this tumor type with concurrent chemoradiotherapy.

Abstract
We present a case of small cell esophageal carcinoma (SCEC) treated with alternated chemotherapy (including cisplatin, etoposide, vincristine, cyclophosphamide and doxorubicin) and irradiation (36 Gy) followed by surgery. Despite a pathological complete response, the patient died of regional disease recurrence 29 months after the diagnosis. We reviewed the available literature on SCEC with regard to the incidence, clinical symptoms, radiological signs, diagnostic workup, therapeutic modalities and prognosis of this malignancy.

Abstract
A 41-year-old female presented with a pedunculated mass in the upper esophagus and bilateral lymphadenopathy. Biopsies suggested a neuroendocrine tumor, possibly carcinoid, and ensuing imaging revealed cervical lymph node metastases. The esophageal mass was removed endoscopically and discovered by pathologists to closely resemble medullary thyroid carcinoma (MTC) on immunohistochemistry staining. Following surgery, further work up demonstrated very high serum calcitonin levels, suggestive of medullary thyroid carcinoma, however the thyroid gland was normal on ultrasound. The patient underwent a neck dissection to remove the lymph node metastases and subsequently her calcitonin levels dropped to 0 ng/mL, indicating remission. It appears that the primary tumor was not in the thyroid, but in the cervical esophagus. The thyroid has appeared normal on multiple ultrasounds without any detectable nodules or masses. This is quite a unique case because this patient presented with a tumor resembling medullary carcinoma of the thyroid that presented as a pedunculated mass in the cervical esophagus. The actual final diagnosis of this mass in the cervical esophagus was neuroendocrine tumor (NET), consistent with a carcinoid tumor, not ectopic MTC. This case report highlights that calcitonin-secreting tumors outside the thyroid should not lead to erroneous recommendations for thyroidectomy.

Abstract
BACKGROUND: Most prevalent esophageal neoplasm is squamous cell carcinoma and adenocarcinoma. Other tumors are uncommon and poorly studied. Primary neuroendocrine esophageal neoplasm is a rare carcinoma and most of its therapy management is based on lung neuroendocrine studies. Neuroendocrine tumors can be clustered in the following subtypes: high grade (small cell carcinoma or large cell carcinoma) and low grade (carcinoids). OBJECTIVE: The present study aims to assess clinical and pathological neuroendocrine esophageal tumors in a single oncologic center. METHODS: A retrospective analysis of patients and review of the literatures was performed. RESULTS: Fourteen patients were identified as neuroendocrine tumors, 11 male and 3 female patients. Mean age was 67.3 years old. Ten patients were classified as small cell, 3 as large cell and 1 as carcinoid. Four patients presented squamous cell carcinoma simultaneously and 1 also presented adenocarcinoma. Main sites of metastasis were liver, peritoneum, lung and bones. Most patients died before 2 years of follow-up. Patient with longer survival died at 35 months after diagnosis. CONCLUSION: Neuroendocrine esophageal tumors are rare; affect mainly men in their sixties or seventies. High grade tumors can be mixed to other subtypes neoplasms, such as adenocarcinoma and squamous cell carcinoma. Most of these patients have poor overall survival rates.

Abstract
Background Metastatic melanoma involving the esophagus is rare; the occurrence of metastatic melanoma in a background of Barrett esophagus is rarer still. We report a case of an 80 year-old male who presented to our institution for workup of Barrett esophagus with high-grade dysplasia and who proved to have metastatic melanoma occurring in the background of Barrett esophagus, the first report of this kind, to our knowledge, in the English literature. Case presentation An 80 year-old Caucasian male was diagnosed at an outside institution with Barrett’s esophagus with high grade dysplasia and presented to our institution for therapy. The patient underwent endoscopic mucosal resection using a band ligation technique of an area of nodularity within the Barrett esophagus. Microscopic examination demonstrated extensive Barrett esophagus with high-grade dysplasia as well as a second tumor which was morphologically different from the surrounding high-grade dysplasia and which was positive for S-100, HMB 45 and Melan-A on immunohistochemistry, consistent with melanoma. Further workup of the patient demonstrated multiple radiologic lesions consistent with metastases. Molecular studies demonstrated that the melanoma was positive for the 1799T>A (V600E) mutation in the BRAF gene. The overall features of the tumor were most consistent with metastatic melanoma occurring in a background of Barrett esophagus with high-grade dysplasia. Conclusion This case demonstrates a unique intersection between a premalignant condition (Barrett esophagus with high grade dysplasia) and a separate malignancy (melanoma). This report also shows the utility of molecular testing to support the hypothesis of primary versus metastatic disease in melanoma.

Abstract
Clinicopathologic features of esophageal neuroendocrine carcinoma (NEC), apart from those of small-cell carcinoma, have not been characterized. We evaluated the clinicopathologic features and prognosis including overall survival of NEC of the esophagus. We identified 40 patients with esophageal NEC from our institutional database. All cancers had been clinically staged using endoscopic ultrasonography, computed tomography, and positron emission tomography. Neuroendocrine differentiation was confirmed by immunohistochemical staining. The NEC component was classified into small-cell and large-cell subtypes, and non-neuroendocrine components were evaluated. Patients with locoregional disease were treated with chemoradiation with or without surgery or with surgery only. Patients with distant metastasis were treated with systemic therapy. The extent of residual tumors was evaluated in esophagectomy specimens after preoperative chemoradiation. Twenty-seven patients had large-cell NEC, and 13 had small-cell neuroendocrine carcinoma. An adenocarcinoma component was present in 15 patients and squamous carcinoma component in 1 patient. Synaptophysin was positive in all cases, and chromogranin was positive in 31 cases. Seventeen patients had distant metastasis, and 21 had locoregional disease. Seventeen patients with locoregional disease received preoperative chemoradiation. Disease progressed in 7 patients, and 10 had residual tumor in resection specimens. Overall survival was better with locoregional disease than with distant metastasis (P=0.006). Overall survival was better in patients with non-neuroendocrine component than in patients with pure NEC (P=0.031). There was no difference in prognosis between patients with large-cell NEC and those with small-cell neuroendocrine carcinoma. Esophageal NEC is an aggressive tumor, and patients with mix NEC have better outcome.

Abstract
Most Barrett's oesophagus-associated cancers are adenocarcinomas which occur in a pure form. They are rarely combined with another type of malignancy, such as endocrine tumours. Within the endocrine spectrum, small cell carcinomas (SmCC) usually have a highly aggressive behaviour with a poor prognosis. We report a case of composite SmCC and adenocarcinoma in the setting of a Barrett's oesophagus, in a 54-year-old man. This tumour was identified on a surgical specimen after neoadjuvant treatment with radiotherapy and 5-FU-Cis-platin based chemotherapy. The SmCC component was positive for chromogranin A, synaptophysin, neural cell adhesion molecule and neuron-specific enolase and negative for high molecular weight cytokeratin. The adenocarcinoma component showed a converse phenotype. In our case, the origin of the SmCC component could be explained by the numerous chromogranin A-positive cells observed in the Barrett's oesophagus or by the potential progenitor cells that may be located in the submucosal oesophageal gland ducts and the Barrett's metaplasia. Our report is thus indicative of the high and totipotential risk of Barrett's oesophagus. Moreover, it is particular because of its favourable behaviour, with a 6-year disease-free survival, after neoadjuvant chemoradiation, surgery and postoperative chemotherapy.

Abstract
Extrapulmonary small cell carcinomas (EPSCCs) are uncommon malignant neoplasms with a reported incidence of 0.1% to 0.4% in the United States. Since their first description in 1930, they have been seen in nearly every organ system. Like their more common pulmonary counterparts, EPSCCs are thought to arise from a multipotential stem cell. However, there is recent molecular evidence that small cell elements may arise as a late-stage phenomenon in the genetic progression of more organ-typical carcinomas. The morphologic, immunohistochemical, and ultrastructural features are similar to those described in pulmonary small cell carcinomas (PSCCs). The differential diagnosis of EPSCC includes PSCC, other neuroendocrine tumors, small round blue cell tumors, metastatic melanoma, lymphoma, and poorly differentiated non-small cell carcinomas. Molecular alterations reported to occur in EPSCCs include abnormalities described in PSCC and changes found in carcinomas more typically encountered in the organ from which they arise. In this article we discuss the pathology of EPSCC with a review of theories of histogenesis, sites of occurrence, diagnostic features, differential diagnosis, molecular alterations, and clinical behavior.

Abstract
The concurrence of carcinoid admixed with adenocarcinoma in the gastrointestinal tract is an unusual phenomenon that has been reported in the oesophagus, stomach, small intestine, appendix, colon and rectum. These mixed or 'composite' tumours seem to be derived from a multipotential stem cell capable of bidirectional differentiation and have a worse prognosis than ordinary adenocarcinoma. Chromogranin-A staining has increased the diagnostic yield for detecting these tumours and provides information for perioperative management and long-term prognosis. We describe a patient who presented to our department due to painful defecation. Sigmoidoscopy demonstrated a mass in the anal canal. Histology revealed that the tumour was a mixed carcinoid-adenocarcinoma neoplasm. To our knowledge, this is the first report in the English literature of a composite tumour of the anal canal.
