Introduction Lung carcinoid tumors are neuroendocrine neoplasms, less frequent than other lung tumors. They are subdivided into typical carcinoids (TC) and atypical carcinoids (AC), according to the rate of mitosis and the presence of necrosis. Lung carcinoids are often asymptomatic and only discovered incidentally. They may also present with cough, wheezing, asthma, and chronic obstructive pulmonary disease, chest pain, and hemoptysis depending on the location of the tumor and, less commonly, present with carcinoid syndrome...

Pulmonary carcinoids are relatively rare tumors with low metastatic potential. Pleural carcinomatosis of a bronchial carcinoid has only been reported in 4 cases. Due to the rarity of this condition, there are no guidelines for its treatment or management. We report a case of atypical carcinoid with local recurrence and pleural metastases treated by video-assisted thoracoscopic surgery lobectomy and total pleurectomy with photodynamic therapy after non-radical wedge resection.

Introduction: Mixed neuroendocrine non-neuroendocrine neoplasm (MiNEN) is a rare form of neuroendocrine neoplasms (NENs). The purpose of this study was to investigate the characteristics and survival profile of appendiceal MiNENs, with a view of providing robust clinical features of this rare disease. Methods: Patients were selected from the Surveillance, Epidemiology, and End Results database (2004-2016). The prognosis of MiNEN ( n = 315) was compared with other histological subtypes including neuroendocrine tumor (NETs) ( n = 1734), neuroendocrine carcinoma (NECs) ( n = 375), goblet cell carcinoid (GCC) ( n = 968), signet ring cell carcinoma ( n = 463), mucinous adenocarcinoma (MAC) ( n = 2355), and non-mucinous adenocarcinoma (NMAC) ( n = 1187) in the appendix...

The aim of our study was to explore the value of the 8th edition TNM staging system on evaluating the prognosis of colorectal carcinoid. Colorectal carcinoid patients between 1988 and 2015 were selected in the Surveillance, Epidemiology, and End Results Program (SEER) database for analysis. About 4286 patients with colorectal carcinoid tumors were identified, of which were carcinoid tumor NOS (n = 1726), neuroendocrine carcinoma (NEC) (n = 1346) and other carcinoid tumor (OCT) (n = 591). Worsening 10-year CSS rates with increasing N status, M status, and SEER historic stage were demonstrated across all three above groups (all P < ...

Carcinoids have been classified according to their embryonic origin in the past and are now categorized and classified as neuroendocrine tumors, including low malignant typical carcinoids, moderate malignant atypical carcinoids, and highly malignant large cell neuroendocrine and small cell carcinomas. A typical carcinoid is a previously used term for the current designation of a grade I neuroendocrine tumor, well differentiated, belonging to a group of rare tumors with a good prognosis with metastasis of less than 15% with a five-year survival of more than 90%, rarely producing serotonin...

Goblet cell carcinoid (GCC) of the perforated appendix is rare, and its pathological features and prognosis remain poorly described. A 71-year-old woman was admitted to our hospital for right lower abdominal pain, vomiting, and high-grade fever. She was diagnosed with acute appendicitis and underwent emergency laparoscopic appendectomy. Intraoperative examination revealed an enlarged and perforated appendix. Histopathological examination revealed GCC of the appendix with subserosal invasion. She underwent laparoscopic ileocecal resection with lymph node dissection (D3) following appendectomy...

BACKGROUND Carcinoid tumor is the most frequent neuroendocrine tumor (NET) that causes liver metastases. One of the best methods to assess this type of pathology is magnetic resonance imaging with hepatocyte-specific contrast media with low molecular weight gadolinium chelate Gd-BOPTA. As these lesions do not contain hepatocytes, they present as hypointense on MRI in comparison with liver tissue which enhances this type of contrast. CASE REPORT In this article, we present a case of a 65-year-old female patient who was admitted to the Emergency Department with abdominal pain...

Monjur Ahmed
Gastrointestinal neuroendocrine tumors are rare slow-growing tumors with distinct histological, biological, and clinical characteristics that have increased in incidence and prevalence within the last few decades. They contain chromogranin A, synaptophysin and neuron-specific enolase which are necessary for making a diagnosis of neuroendocrine tumor. Ki-67 index and mitotic index correlate with cellular proliferation. Serum chromogranin A is the most commonly used biomarker to assess the bulk of disease and monitor treatment and is raised in both functioning and non-functioning neuroendocrine tumors...

Purpose: Nuclear medicine imaging can provide a noninvasive means of distinguishing inflammatory mass lesions from oncologic intraocular tumors. Observation: We report a case of paraneoplastic ocular sarcoidosis with choroidal mass lesions that was initially concerning for choroidal metastasis of a primary carcinoid tumor. PET CT was utilized with two different tracers to characterize the choroidal mass as being FDG-avid, consistent with a sarcoid-like lesion, and lacking the Gallium (Ga-68) DOTATAE uptake of carcinoid tumor metastases...

Mediastinal neuroendocrine tumors (NETs) are very rare. They have been estimated to account for approximately 2%-4% of all anterior mediastinal neoplasms. Carcinoid tumors are a type of NET that can occur in a number of locations. They arise from endocrine amine precursor uptake and decarboxylation cells that can be found in organs such as the lungs. In general, they are slow growing tumors but are nevertheless capable of metastasizing. We present the case of a carcinoid tumor of the anterior mediastinum in a 38-year-old woman presented to our hospital with a 4-month history of worsening breathless and cough...

Small bowel neuroendocrine tumors (SB NETs) are increasing in frequency and becoming more common in surgical practice. It is often difficult to make the diagnosis of a SB NET at an early stage, as the primary tumor tends to be small and patients are asymptomatic until there is regional or distant metastasis, when they develop abdominal pain, partial obstruction, or bleeding and/or develop carcinoid syndrome. Despite this advanced presentation at the time of diagnosis, patients with metastatic SB NETs, as compared to other gastrointestinal malignancies, have favorable survival, which can be improved by appropriate surgical interventions...

Bronchial carcinoids are uncommon tumors accounting for 20 to 30% of all neuroendocrine tumors and about 1-2% of all cancers of pulmonary origin. Bronchial carcinoids are well-differentiated neuroendocrine tumors and have a favorable survival outcome when compared with other subtypes of lung cancers. Treatment of bronchial carcinoids is not simple owing to intricacy of symptom presentation and heterogeneity of disease biology. Successful treatment of patients requires a multimodality approach. Resection is curative in the majority of patients with localized tumors and adjuvant treatment is not routinely recommended...

Neurofibromatosis type I (NF1) is an autosomal dominant genetic disorder associated with characteristic skin findings, as well as a fourfold increase in risk of malignancy. NF1 patient malignancies commonly include the central and peripheral nervous system, but these patients are also at high risk of developing gastrointestinal (GI) tumors. While most often these GI tumors are benign upper GI neurofibromas; clinicians should have a high suspicion for malignant tumors, degeneration into a malignant peripheral nerve sheath tumor or less common associated malignancies such as well-differentiated neuroendocrine tumor (formerly carcinoid tumor), when patients present with multiple GI tumors...
