Well-differentiated neuroendocrine tumors (NETs) are globally increasing in prevalence and the liver is the most common site of metastasis. Neuroendocrine liver metastases (NELM) are heterogeneous in clinical presentation and prognosis. Fortunately, recent advances in diagnostic techniques and therapeutic strategies have improved the multidisciplinary management of this challenging condition. When feasible, surgical resection of NELM offers the best long-term outcomes. General indications for hepatic resection include performance status acceptable for major liver surgery, grade 1 or 2 tumors, absence of extrahepatic disease, adequate size and function of future liver remnant, and feasibility of resecting >90% of metastases...

BACKGROUND Completely isolated enteric duplication cysts (CIDCs) are rare malformations that can occur at any site in the gastrointestinal system. This report describes a woman with a CIDC and an incidental appendiceal neuroendocrine tumor (ANET). CASE REPORT A 26-year-old woman who presented with dysmenorrhea was assessed by ultrasound (US), which revealed a pelvic mass. Other imaging modalities, including magnetic resonance imaging (MRI), failed to clarify the origin of the mass. Intraoperative findings during diagnostic laparoscopy revealed an isolated, ovaloid mass with autonomous peristalsis and a short pedicle towards the root of the ileal mesentery...

Purpose: Neuroendocrine tumors (NETs) associated with carcinoid syndrome (CS) overproduce serotonin, mediated by tryptophan hydroxylase-1 (TPH1). The TPH inhibitor telotristat ethyl (TE) reduces peripheral serotonin and relieves CS symptoms. We conducted a real-world clinical practice study to explore the effects of TE on tumor growth in patients with NETs and CS. Patients and Methods: Single-arm, pre/post chart review study of patients with advanced NETs who received TE for ≥6 months and had ≥2 radiological scans within 12 months before and ≥1 scan after TE initiation...

<b/> Typical carcinoid tumors arise from neuroendocrine cells, many of which are present in the digestive tract and lungs. Tumors occurring in the nose and paranasal sinus area are very rare. We encountered a patient with a typical carcinoid tumor that arose in the sphenoid sinuses, and we report the case with a review of the literature. The patient was a 53-year-old woman presented with right-side headache and repeatedly rhinorrhea for half a year. The sinus CT revealed a soft tissue mass in the right sphenoid sinus, MR showed equal T1 signal and T2 signal tissue, and enhanced MR showed abundant blood perfusion in the arterial phase before surgery...

A 38-year-old Japanese man who had been diagnosed with appendiceal carcinoid and undergone ileocecal resection 8 years before, presented with duodenal obstruction caused by a submucosal tumor-like appearance. He was diagnosed with long-term recurrence of appendiceal goblet cell carcinoid (GCC) with a multi-morphological pattern based on the histological assessment of a duodenal biopsy and his previously resected appendix. He underwent subtotal stomach-preserving pancreaticoduodenectomy combined with resection of an ileo-colic anastomotic lesion...

Nonpeptide sst2 agonists can provide a new treatment option for patients with acromegaly, carcinoid tumors, and neuroendocrine tumors. Our medicinal chemistry efforts have led to the discovery of novel 3,4-dihydroquinazoline-4-carboxamides as sst2 agonists. This class of molecules exhibits excellent human sst2 potency and selectivity against sst1, sst3, sst4 and sst5 receptors. Leading compound 3-(3-chloro-5-methylphenyl)-6-(3-fluoro-2-hydroxyphenyl)-N,7-dimethyl-N-{[(2S)-pyrrolidin-2-yl]methyl}-3,4-dihydroquinazoline-4-carboxamide (28) showed no inhibition of major CYP450 enzymes (2C9, 2C19, 2D6 and 3A4) and weak inhibition of the hERG channel...

A 27-year-old male patient presented with cough and right-sided, light thoracic pain. His physical appearance showed typical features of gigantism. Subsequently, further diagnostic work-up showed elevated level of growth hormone and a huge tumor of the right lung, identifying a typical pulmonary carcinoid tumor (TPCT). Curative surgery was performed leading to normalization of the elevated growth hormone levels few days after surgery. Two- and five-year follow-up showed no signs of recurrence. Respected to tumor size, we determined the largest TPCT to be reported in medical literature history...

We report a case of a retropubic parasymphyseal cyst in a 69-year-old multiparous female with a protracted history of metastatic small bowel carcinoid (neuroendocrine) tumor. Cysts related to the pubic symphysis are uncommon, and mostly reported in subpubic location. They may be confused with primary vulvar masses, malignant bone tumors or metastatic disease. In our case, encapsulation, lack of solid components or diffusion restriction, communication with the symphysis, lack of activity on Gallium-68-Dotatate PET/CT and signal characteristics on MRI similar to those previously reported in literature for subpubic cysts all aided in eventual diagnosis...

A 68-year-old woman with a history of multiple myeloma on regular hematological follow-up and with no previous relevant gynecological diseases was found to have an incidental focal uptake by the right ovary at C-methionine PET/CT (C-MET). Transvaginal ultrasound was then performed showing a 2-cm solid right ovarian mass with irregular borders and moderate vascularization at color Doppler examination. Therefore, the patient underwent bilateral salpingectomy, and the final histological results revealed a rare presentation of mature teratoma with insular carcinoid tumor arising from the right ovary...

Up to 35% of small bowel neuroendocrine tumors (SBNETs) may present with an acute intra-abdominal complication including obstruction, perforation, bleeding or ischemia and may require emergency surgical treatment in centers not normally accustomed to managing patients with neuroendocrine tumors. These patients may have a known diagnosis of SBNET, be suspected as suffering from SBNET or have SBNET diagnosed as an incidental finding on presenting radiology or postoperative pathology. Perioperative priorities include obtaining both clinical and radiological staging with cross-sectional imaging and clinical examination, screening for the presence of carcinoid syndrome and right-sided cardiac disease and assessment of prognosis...

Pulmonary large cell neuroendocrine carcinoma (LCNEC) is a rare and aggressive malignancy that is strongly linked to smoking and notoriously difficult to diagnose and treat. Recent molecular data reveal that it represents a biologically heterogeneous group of tumors, characterized by morphologic and genomic diversity that straddles small cell and non-small cell lung carcinomas (NSCLCs), and in a minority of cases atypical carcinoids. This review provides an update on recent molecular and clinical developments in LCNEC with the main focus on practical approach to pathologic diagnosis using illustrative examples of the main differential diagnostic considerations...

Lung nodules are often incidentally discovered on lung imaging and can be solitary, which makes them suspicious for tumors, or multiple, which can be suggestive of an infectious process. A bronchial carcinoid is a rare pulmonary neoplasm, representing 1.2% of all primary pulmonary tumors. We report a case of incidentally discovered multiple lung nodules in an asymptomatic human immunodeficiency virus (HIV) patient, which turned out to be a tumor, necessitating the need for keeping a broad differential, a high degree of clinical suspicion, and long-term follow-up for the optimal management of the patient...

Neuroendocrine tumors (NETs) frequently overexpress somatostatin receptors (SSTR) on their cell surface. The first-line pharmacological treatment for inoperable metastatic functioning well-differentiated NETs are somatostatin analogs. On second line, Lu-DOTA-TATE (177 Lu-DOTA0 Tyr 3 octreotate) has shown stabilization of the disease and an increase in progression free survival, as well as effectiveness in controlling symptoms and increasing quality of life. The management of functional NETs before and during LU-DOTA-TATE treatment is specially challenging, as several complications such as severe carcinoid and catecholamine crisis have been described...
