A healthy 52-year-old man started to have few minutes spells of palpitation, tachycardia, hot flashes, and chest tightness. He had a lab work-up for carcinoid, including 5-hydroxyindoleacetic acid (5-HIAA), which was negative. Months later, his symptoms became worse which warranted further investigation to exclude carcinoid disease. Read More

Type A thymoma with simultaneous solitary intrapulmonary metastasis: A case report.

Thorac Cancer 2021 May 7. Epub 2021 May 7.

Department of Oncology, Immunology and Surgery, Nagoya City University Graduate School of Medical Sciences, Nagoya, Japan.

A 79-year-old woman was referred to our facility because of an abnormal chest shadow. Chest computed tomography (CT) showed a solitary right middle lung nodule with a maximum diameter of 3 mm and anterior mediastinal nodule with a maximum diameter of 21 mm. The lung nodule was suspected of being a primary lung cancer rather than a metastatic tumor because there were no primary malignant tumors, apart from an anterior mediastinal tumor visible on diagnostic imaging, including F fluorodeoxyglucose-positron emission tomography, and a solitary lung nodule.

Middle ear adenomatous neuroendocrine tumours: single institution experience with five cases.

Clin Otolaryngol 2021 May 1. Epub 2021 May 1.

APHP, Otology, auditory implants and skull base department, Pitié-Salpêtrière Hospital, Paris, France.

Middle ear adenomatous neuroendocrine tumours are extremely rare causes of middle ear masses.

Hypovascular pancreatic neuroendocrine tumor with hepatic metastases: A case report and literature review.

Radiol Case Rep 2021 Jun 10;16(6):1424-1427. Epub 2021 Apr 10.

Department of Radiology, Ha Noi Medical University, Ha Noi, Vietnam.

Hypovascular pancreatic neuroendocrine tumors are uncommon pancreatic tumors and commonly misdiagnosed as pancreatic ductal adenocarcinoma or chronic mass-forming pancreatitis. The liver is the organ most commonly affected by neuroendocrine tumor metastases but hepatic neuroendocrine tumor metastases are quite difficult to discriminate from other hepatic metastases and primary hepatic tumors. We describe a case of a 47-year-old man with incidentally detected multiple hepatic lesions on ultrasound. Read More

Division of Thoracic Surgery, Kobe University Graduate School of Medicine, Kobe, Hyogo, Japan.

Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune inflammatory disease, occasionally accompanied by malignant tumors. Immunosuppressive therapy is the mainstay treatment for idiopathic NMOSD; no guidelines have been published for paraneoplastic NMOSD because it is rarely reported in the literature. We report a rare case of a 67-year-old man with paraneoplastic NMOSD associated with thymic carcinoid whose cells expressed aquaporin-4 antibody. Read More

Cardiac Imaging in Carcinoid Heart Disease.

JACC Cardiovasc Imaging 2021 Apr 9. Epub 2021 Apr 9.

Department of Medical Sciences, Cardiology, and Clinical Physiology, Uppsala University, Uppsala, Sweden. Electronic address:

Carcinoid disease is caused by neuroendocrine tumors, most often located in the gut, and leads in approximately 20% of cases to specific, severe heart disease, most prominently affecting right-sided valves. If cardiac disease occurs, it determines the patient's prognosis more than local growth of the tumor. Surgical treatment of carcinoid-induced valve disease has been found to improve survival in observational studies. Read More

Efficacy of Lutetium-Peptide Receptor Radionuclide Therapy in Inducing Prolonged Tumour Regression in Small-Bowel Neuroendocrine Tumours: A Case of Favourable Response to Retreatment after Initial Objective Response.

Oncol Res Treat 2021 14;44(5):276-280. Epub 2021 Apr 14.

Digestive Disease Unit, Sant'Andrea University Hospital, ENETS Center of Excellence, Rome, Italy.

Introduction: The efficacy of 177Lu-Dotatate was shown in the NETTER-1 trial, an international, open-label, multicentre phase III clinical trial that evaluated the safety and efficacy of 177Lu-Dotatate in patients with well-differentiated, advanced midgut neuroendocrine tumours (NETs) with evidence of disease progression. Recently, retreatment with peptide receptor radionuclide therapy (PRRT) has been proposed as a valid therapeutic option in patients without other effective options who had responded to initial PRRT; however, data on this therapeutic option are still inadequate.

Case Report: In this report, we present the case of a patient who achieved a delayed complete radiological response after initial 177Lu-Dotatate treatment and who had a complete tumour response with PRRT retreatment 5 years later. Read More

Indian J Pathol Microbiol 2021 Apr-Jun;64(2):376-378

Department of Pathology, Gujarat Adani Institute of Medical Sciences, Bhuj, Kachchh, Gujarat, India.

The carcinoids are the most frequent tumors arising from the appendix, in majority of the cases, these are asymptomatic and are discovered after appendectomy. The lipid-rich carcinoid, also known as clear cell carcinoid; is histologically characterized by the presence of clear vacuoles in the cytoplasm of tumor cells. Only 24 cases of lipid-rich carcinoid of the appendix are described in the English literature, and there is no report of this entity in the Indian literature. Read More
