Introduction. Duodenal gangliocytic paragangliomas (GPs) are a subclass of duodenal neuroendocrine neoplasms and are exceedingly rare. They have been associated with an indolent behavior; however, they can rarely metastasize. Radical resection like a pancreaticoduodenectomy is sometimes indicated. We hereby present a case requiring major surgery and perform a literature search about this disease. Presentation of Case. A 49-year-old Caucasian female, who presented with an upper gastrointestinal bleed, was found to have a hypodense mass in the second/third portion of the duodenum. A biopsy of the mass during upper endoscopy was inconclusive. A pancreaticoduodenectomy was recommended based on the high suspicion for a duodenal adenocarcinoma and was performed successfully. Her final pathology revealed a duodenal gangliocytic paraganglioma. Discussion. The majority of duodenal GPs present as gastrointestinal bleeds while others less commonly present with anemia, abdominal pain, duodenal obstructive symptoms, pancreatitis, or abnormal incidental findings on axial abdominal imaging. Duodenal GPs were initially viewed as benign tumors of the duodenum; however, there have been increasing incidence reports of hematogenous and lymphatic metastasis. Appropriate treatment of duodenal GPs is still controversial and ranges from local endoscopic submucosal resection to major radical surgery. Conclusion. Duodenal GPs are very rare tumors of the second portion of the duodenum presenting with upper gastrointestinal bleeding and local symptoms of surrounding organs. Local or radical resection is usually recommended to prevent bleeding and the minor risk of metastatic spread.

Abstract Background Lung neuroendocrine neoplasms (LNENs) are rare solid cancers, with most genomic studies including a limited number of samples. Recently, generating the first multi-omic dataset for atypical pulmonary carcinoids and the first methylation dataset for large-cell neuroendocrine carcinomas led us to the discovery of clinically relevant molecular groups, as well as a new entity of pulmonary carcinoids (supra-carcinoids). Results To promote the integration of LNENs molecular data, we provide here detailed information on data generation and quality control for whole-genome/exome sequencing, RNA sequencing, and EPIC 850K methylation arrays for a total of 84 patients with LNENs. We integrate the transcriptomic data with other previously published data and generate the first comprehensive molecular map of LNENs using the Uniform Manifold Approximation and Projection (UMAP) dimension reduction technique. We show that this map captures the main biological findings of previous studies and can be used as reference to integrate datasets for which RNA sequencing is available. The generated map can be interactively explored and interrogated on the UCSC TumorMap portal (https://tumormap.ucsc.edu/?p=RCG_lungNENomics/LNEN). The data, source code, and compute environments used to generate and evaluate the map as well as the raw data are available, respectively, in a Nextjournal interactive notebook (https://nextjournal.com/rarecancersgenomics/a-molecular-map-of-lung-neuroendocrine-neoplasms/) and at the EMBL-EBI European Genome-phenome Archive and Gene Expression Omnibus data repositories. Conclusions We provide data and all resources needed to integrate them with future LNENs transcriptomic studies, allowing meaningful conclusions to be drawn that will eventually lead to a better understanding of this rare understudied disease.

Pulmonary carcinoids (PCs) display the common features of all well-differentiated neuroendocrine neoplasms (NEN) and are classified as low- and intermediate-grade malignant tumours (i.e., typical and atypical carcinoid, respectively). There is a paucity of randomised studies dedicated to advanced PCs and management principles are drawn from the larger gastroenteropancreatic NEN experience. There is growing evidence that NEN anatomic subgroups have different biology and different responses to treatment and, therefore, should be investigated as separate entities in clinical trials. In this review, we discuss the existing evidence and limitations of tumour classification, diagnostics and staging, prognostication, and treatment in the setting of PC, with focus on unmet medical needs and directions for the future.

Background: Carotid body paragangliomas are rare neuroendocrine neoplasms of chromaffin negative glomus cells. This case report explains an atypical case with unusual presentation and treatment. Case Report: A healthy smoker technician by profession was brought to the emergency room (ER) with coprolalia. The general physical exam did not reveal any information. His history revealed unilateral tinnitus and odynophagia leading to a consultation by the neurologist with head imaging. Acoustic neuroma was ruled out and the caregiver was asked to elaborate the events mentioned in the history and a psychiatric examination was done. The personality changes were evaluated by the psychiatrist that showed overlapping of delirium and depression. The patient was further examined by a vascular surgeon. After careful revisiting of the history, examination and indication of tender mass in the neck by the patient's vascular surgeon, the diagnosis of carotid body paraganglioma was made which was followed by surgical resection for treatment. Conclusion: Carotid Body Paragangliomas are very vascular structures and their manipulation in a surgery setting requires expertise. This case presented with personality changes and tinnitus, a very less likely event to occur in a carotid body tumor. The present care report, thus adds on to the literature of carotid body tumors and its presenting symptoms.
