Malignant tumors account for most sources of ectopic ACTH Cushing syndrome (EA-CS). Early localization of the source and complete removal can be curative and also prevent metastasis. Diagnostic CT is known to perform better than PET/CT (low dose) in characterizing lung pathologies. However, bronchial carcinoids, a common source of EA-CS, may be difficult to detect on chest CT scan especially when it is small and located close to the hilar region. We present a case of EA-CS due to bronchial carcinoid, which was easily seen on Ga DOTANOC PET/CT after a diagnostic chest CT was reported as normal...

INTRODUCTION: Transient jejunal intussusception in an adult is a rare clinical finding as reported in the English literature. The diagnosis is usually a matter of exclusion given the extremely rare nature of this medical condition. PRESENTATION OF THE CASE: A young female presented to our hospital with abdominal pain and distention of six months duration. The episodes were intermittent in nature and resolved with conservative management. The aetiology remained obscure until a computerized tomography(CT) scan diagnosed a small bowel intussusceptionIntraoperatively a small bowel tumour was identified and resected...

BACKGROUND/AIM: Large-cell neuroendocrine carcinoma (LCNEC) of the lung is a relatively uncommon and aggressive subset of pulmonary neuroendocrine tumors, which include typical and atypical carcinoid, and small-cell lung cancer. LCNEC of the lung accounts for no more than 1% of all lung cancers. LCNECs show features of high-grade neuroendocrine tumors and patients with LCNEC have a very poor prognosis. MATERIALS AND METHODS: Twenty-five patients (22 males and 3 females; mean years 60...

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...

Neuroendocrine tumors (NETs) are aggressive diseases developing from neuroendocrine cells that most frequently involve the gastro-entero-pancreatic tract and the lung, but more rarely are found in almost all body tissues. Limited biological and clinical data are currently available for NETs in uncommon sites, such as female genital tract. NETs represent 0.9% to 1.5% of the tumors of the uterine cervix. They are more likely to have lymph-vascular space invasion and lymph node involvement, and to develop local and distant relapses when compared with the mostly common cervical squamous cell carcinomas or adenocarcinomas...

Optimal histopathological analysis of biopsies from metastases of neuroendocrine tumor (NET) of the lung requires more than morphology only. Additional parameters such as Ki-67 labeling index are required for adequate diagnosis, but few studies have compared reproducibility of different counting protocols and modalities of reporting on biopsies of lung NET. We compared the results of four different manual counting techniques to establish Ki-67 LI. On 47 paired biopsies and surgical specimens from 22 typical carcinoids (TCs), 14 atypical carcinoids (ACs), six large cell neuroendocrine carcinomas (LCNECs), and five small cell carcinomas (SCCs) immunohistochemical staining of Ki-67 antigen was performed...

We report a unique case of synchronous double primary gastric cancer consisting of adenocarcinoma components with micropapillary features and composite glandular-endocrine cell carcinoma components. The patient was a 53-year-old man presenting with a 6-month history of epigastric pain and diarrhea. A subtotal gastrectomy was performed. Histologically, one tumor was composed of micropapillary carcinoma components (50%) with tight clusters of micropapillary aggregates lying in the empty spaces, admixed with moderately differentiated adenocarcinoma components...

Gastrointestinal carcinoids have occasionally been reported in patients with autoimmune diseases. We report a middle-aged woman who presented with episodic hypertension and a skin rash. Initial evaluation led to the diagnosis of systemic lupus erythematosus for which the patient was treated. Further investigations revealed the presence of a carcinoid tumour in the pituitary. Although gastrointestinal carcinoids associated with autoimmune diseases have been seen occasionally, to our knowledge, extragastric carcinoid coexisting with an auto- immune disorder has never been reported before...

The objective of this article is to determine the relevance of close postresection surveillance for bronchopulmonary carcinoid. From 2006 to 2013, 57 patients underwent lung resection for bronchopulmonary carcinoid. They were assessed for effects of clinical presentation, subtype, stage, and tobacco use on survival and recurrence. Utility of bronchoscopy and radiographic surveillance was reviewed. Mean follow-up was 2.1 ± 1.7 years. Carcinoid patients presented at a young age (51 ± 15 years) with normal spirometry regardless of smoking status (forced 1-second expiratory volume, 88% ± 19% for never smokers vs 87% ± 16% for smokers)...

Esophageal carcinoids are exceedingly rare and only a few limited cases have been reported. Because knowledge about esophageal carcinoid is based primarily on case reports, the treatment of choice has not been settled. We report here on a localized carcinoid tumor in the esophagogastric junction. As our initial biopsy was nearly equal for the excision, we only performed coagulation ablation therapy instead of a wide excision which is traditionally recommended. The patient is free of recurrence so far during 50-month follow-up...

A 26-year-old female with carcinoid heart disease consisting of severe pulmonary and tricuspid valve stenosis was admitted with line associated sepsis. She recovered from sepsis with antibiotics and aggressive fluid resuscitation but became grossly volume overloaded with evidence of tense ascites and lower extremity edema. She developed worsening renal and hepatic function due to congestive nephropathy and hepatopathy, which did not respond to intravenous diuretics, and she was deemed too sick for surgical pulmonary and tricuspid valve replacement...

BACKGROUND: Currently, molecular profiles and prognosis of primary pulmonary neuroendocrine carcinoma (PNC) are poorly elucidated. The present study was designed to evaluate genomic abnormalities and survival in patients with primary PNC. METHODS: Completely resected PNC samples were collected from Zhejiang Cancer Hospital during the period of 2008 to 2015. Nine driver genes, including 6 mutations (EGFR, KRAS, NRAS, PIK3CA, BRAF, and HER2) and 3 fusions (ALK, ROS1, and RET), were evaluated by reverse transcription-polymerase chain reaction (RT-PCR)...
