Purpose: We report an unusual case of trabecular carcinoid of the ovary with orbital involvement. Methods: We encountered a 49-year-old woman with a complaint of bilateral proptosis. Ocular examination revealed severe bilateral proptosis and signs of corneal exposure. Orbital CT scan showed massive enlargement of extraocular muscles and optic nerve compression. The patient medical history showe...

OBJECTIVE To establish reproducible electron microscopic criteria for identifying the four major types of neuroendocrine tumors of the lung: carcinoid; atypical carcinoid; large cell neuroendocrine carcinoma; and small cell carcinoma. METHODS Measurements were made on electron micrographs using a digital image analyzer. Sixteen morphometric variables related to tumor cell differentiation were...

Endoscopic treatment can be a curative option for small carcinoid tumors with an extremely low risk of metastasis. Since most carcinoid tumors are characterized by a specific growth pattern in the submucosal (SM) layer, specialized endoscopic techniques for deeper resection to achieve clear vertical margins are needed. The endoscopic submucosal dissection (ESD) method in the SM space is superio...

Carcinoid tumors are malignancies originating from neuroendocrine cells, most commonly encountered in the gastrointestinal tract, in a rate of 64%, with the majority affecting the ileum. Certain genetic syndromes sometimes include carcinoid tumors in their phenotype. These malignancies may be rather asymptomatic, although occasionally they behave aggressively. They are typically diagnosed due t...

Ectopic production of adrenocorticotropic hormone by carcinoid tumors is relatively uncommon and may not be recognized by physicians. This report describes a woman who had Cushing syndrome from the ectopic secretion of adrenocorticotropic hormone by a carcinoid tumor. Her cause of death was a pneumonia that may have been secondary to her untreated hypercortisolism. There are threeinstructive el...

BACKGROUND Pulmonary carcinoids (PCs) are rare tumors. As there is a paucity of randomized studies, this expert consensus document represents an initiative by the European Neuroendocrine Tumor Society to provide guidance on their management. PATIENTS AND METHODS Bibliographical searches were carried out in PubMed for the terms 'pulmonary neuroendocrine tumors', 'bronchial neuroendocrine tumor...

Sporadic gastric carcinoid tumors are relatively infrequent malignancies of the stomach. Tumors measuring less than 1 cm can sometimes be safely removed endoscopically; however, larger neoplasias require surgical ablation. The present case report represents a gastric carcinoid tumor laparoscopically resected in a patient with a history of hematemesis. The tumor was first marked endoscopically w...
