BACKGROUND: Near-infrared (NIR) imaging using the second time window of indocyanine green (ICG) allows localization of pulmonary, pleural, and mediastinal malignancies during surgery. Based on empirical evidence, we hypothesized that different histological tumor types fluoresce optimally at different ICG doses. STUDY DESIGN: Patients with thoracic tumors biopsy-proven or suspicious for malignancy were enrolled in an NIR imaging clinical trial. Patients received a range of ICG doses one day prior to surgery: 1 mg/kg (n=8), 2 mg/kg (n=8), 3 mg/kg (n=13), 4 mg/kg (n=8), and 5 mg/kg (n=8)...

INTRODUCTION: Multiple tumors belong to rare cancers. Almost all malignancies may occur in combination, the most common combination being gastrointestinal cancer with respiratory or urogenital tract cancer and with breast cancer in females. CASE REPORT: In 1999, a 66-year-old patient was diagnosed with a rectosigmoid tumor histologically proven as adenocarcinoma. Rectosigmoid resection was performed, followed by adjuvant radiotherapy and the Mayo Clinic FU/FA chemotherapy regimen...

RATIONALE: Thymic carcinoids are a rare type of malignant neuroendocrine tumors which have a poor prognosis due to their distant metastasis, invasive behaviour, and postoperative recurrence. Surgical resection is still the fundamental mode for treating thymic carcinoids. Here, we report the rapid shrinkage of an atypical thymic carcinoid with multiple metastases following chemoradiation plus octreotide as a first-line therapy PATIENT CONCERNS:: A 39-year-old Chinese man presented with chest tightness, dyspnea with a history of lumbago and untreated malignant thymoma...

BACKGROUND: Endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) is the primary modality for mediastinal lymph node staging in lung carcinoma. We aimed to evaluate its utility in extra-pulmonary malignancies (EPM). METHODS: Database search of EBUS-TBNA aspirations (2013-2017) done in patients with known/suspected EPMs and mediastinal lymphadenopathy/masses was performed. All archived cytology/histology material was reviewed and categorized as positive, negative and unsatisfactory...

Background: Pulmonary and mediastinal paragangliomas are rare tumors that may have neuroendocrine activity or be non-functional, incidental, in asymptomatic patients, or causing mass effect symptoms. Although being low-grade tumors, they can display an aggressive behaviour, developing local infiltration and distant metastases. We report our experience with three endothoracic paragangliomas and a Literature review, to point out diagnostic difficulties and problems related to surgical treatment...

Large cell neuroendocrine carcinoma (LCNEC) is a highly malignant cancer originally found in lung in 1991. In extremely rare occasions, primary LCNEC is found in the mediastinum; approximately 40 of such cases have been reported. Due to the limited number of reported cases, a standardized treatment protocol has yet to be established. We report a case of a 66-year-old woman with primary mediastinal LCNEC who presented with superior vena cava syndrome. Emergent radiotherapy was performed, followed by systemic chemotherapy with cisplatin and etoposide, which resulted in a dramatic tumor reduction...

Paragangliomas are extra-adrenal tumors that are derived from neuroendocrine chromaffin cells. The rare disease has a variable presentation depending upon its anatomic location and functionality. We describe the case of a 56-year-old female patient who had an incidental mass found on imaging. The patient underwent biochemical testing and a mediastinal biopsy due to the nonspecific imaging findings. The mediastinal mass was resected through hemisternotomy and found to be a functional paraganglioma. This case highlights the importance of radiologists to consider the prospect of paragangliomas in the differential diagnosis of an intra-thoracic mass...

INTRODUCTION: Paragangliomas (PGs) or extra-adrenal pheochromocytomas are rare neuroendocrine neoplasms of ubiquitous distribution. Those that produce excess catecholamine are categorized as functional, and those that do not are categorized as nonfunctional. Although modern medical technology is becoming more widespread, there are still substantial risks of misdiagnosis or missed diagnosis of PGs. CASE PRESENTATION: A 38-year-old woman who lived in an autonomous region of inner Mongolia presented complaining of having experienced coughing for approximately the past month...

Ectopic ACTH syndrome (EAS) is a potentially fatal endocrine disease that results from a variety of neuroendocrine tumors (NETs), such as small cell lung cancer (SCLC) and bronchial typical carcinoid. Typical carcinoid is usually slow growing, not associated with plasma progastrin releasing peptide (ProGRP) elevation. Here, we report a 47-year-old female smoker with progressive typical carcinoid and plasma ProGRP elevation. Several types of Cushingoid features were found on physical examination. In addition, laboratory examination showed elevated plasma ACTH and serum cortisol levels...

Extrapulmonary small cell neuroendocrine carcinoma (SNEC) is an extremely rare and highly malignant tumor with a poor prognosis. Multiple metastases of SNEC are even more rare, and patients with locally advanced and metastatic disease generally face a poor outcome. To date, only a few cases of SNEC have been reported. Here, we describe a rare case of a 70-year-old female patient with SNEC of the tonsil who presented with multiple metastases and had achieved a complete response (CR) of the primary lesion and cervical lymph nodes for more than 1 year after receiving palliative chemotherapy...

RATIONALE: Small cell lung cancer accounts for 15-20% of all lung cancers and is the most common pulmonary neuroendocrine neoplasm. Most small cell lung cancers arise from lobar or main bronchi, the most common manifestations of small cell lung cancer is a large mass centrally located within the lung parenchyma or a mediastinal mass involving the hilus. Small cell lung cancer is easily ignored by clinicians without lung parenchyma and hilus involvement. Here, we report a case of small cell lung cancer, which was misdiagnosed as the lymphoma in contrast enhanced CT and Ga-DOTA-NOC PET/CT imagings...

BACKGROUND: Mixed adenoneuroendocrine carcinoma (MANEC) is a tumor of the gastrointestinal tract that contains both exocrine and endocrine components, with each component exceeding 30% of the total tumor area. Because MANECs are exceedingly rare, no therapeutic strategies have been established yet. CASE PRESENTATION: An 81-year-old man was referred to our hospital with a 5-month history of dysphagia. Esophagogastroduodenoscopy revealed an ulcerated mass in the lower thoracic esophagus, extending up to the esophagogastric junction (33 to 40 cm from the incisors)...

Primary neuroendocrine tumors of the thymus are unusual anterior mediastinal tumors with a variable prognosis. A retrospective analysis of five patients with primary neuroendocrine tumors of the thymus admitted to the Gujarat Cancer and Research Institute, Ahmedabad, between 2012 and 2016, was done to study the clinical profile and outcome of these patients. The role of various prognostic factors such as surgical resection, histological grade, and Masaoka-Koga staging was also analyzed. Majority of the patients present with signs and symptoms related to a rapidly expanding mediastinal mass, such as breathlessness, facial puffiness, edema over the neck and extremities, chest pain, and other features of superior vena cava (SVC) syndrome...

Large cell neuroendocrine carcinoma (LCNC) is a rare and aggressive cancer accounting for 3% of all lung cancers. A small percentage of LCNC called combined LCNC, can be seen in combinations with other lung tumor types. Multimodal therapy is proposed for this type of tumor but there is no any significant therapy since it is very rare tumor. This patient was a 66-year male and a heavy smoker with no symptoms of lung disease. Computed tomography core biopsy showed suspected adenocarcinoma. Right lower lobectomy was performed with mediastinal lymph node dissection via mini thoracotomy...

Pulmonary neuroendocrine tumors are rare, and there have been very few reports regarding optimal chemotherapeutic regimens. Two molecular targeted agents, everolimus and sunitinib, have recently been shown to provide an additional treatment benefit for pulmonary neuroendocrine tumors. However, little information is available regarding the usefulness of streptozocin chemotherapy. Here, we encountered a case of relapsed and refractory mediastinal atypical carcinoid tumor associated with multiple endocrine neoplasia type 1 for various cytotoxic and molecular targeted agents...

We report a case of acute pancreatitis secondary to pancreatic neuroendocrine tumor. A 46-year old man presented with upper abdominal pain. The serum amylase and lipase were elevated. Abdominal computed tomography (CT) and magnetic resonance cholangiopancreatography revealed a 1.7 cm sized mass at the pancreas body with a dilatation of the upstream pancreatic duct and mild infiltrations of peripancreatic fat. An endoscopic ultrasound-guided fine needle biopsy was performed for the pancreatic mass, but only necrotic tissue was observed on the pathologic examination...

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the most common cause of euvolemic hypo-osmotic hyponatremia. There are several etiologies of SIADH including neuroendocrine tumor, pulmonary disease, infection, trauma, and medications. Here, we report a case of SIADH associated with a schwannoma involving the mediastinum in a 75-year-old woman who presented with nausea, vomiting, and general weakness. Laboratory testing showed hypo-osmolar hyponatremia, with a serum sodium level of 102mmol/L, serum osmolality of 221mOsm/kg, urine osmolality of 382mOsm/kg, urine sodium of 55 mmol/L, and plasma antidiuretic hormone (ADH) of 4...

Primary neuroendocrine tumors of the thymus (NETTs) are rare and biologically very aggressive neoplasms, usually located in the anterior mediastinal space. They are more frequently observed in males, in their fourth/fifth decades of life. In 50% of cases, NETTs are associated with endocrinopaties [Cushing's syndrome, acromegaly or Multiple Endocrine Neoplasia-1 (MEN-1) syndrome]. NETTs very often present with invasion of the surrounding mediastinal anatomical structures. Surgery, even in advanced stages, is the mainstay of treatment: a compete resection through a median sternotomy or a combined access (sternotomy + thoracotomy) should be always attempted...
