Carcinoid tumors are rare and slow growing malignancies derived from enterochromaffin cells. Two-thirds of carcinoid tumors arise in the gastrointestinal tract, and in 3% of these cases the primary site cannot be determined. Presenting symptoms depend on the location of the primary tumor but may be nonspecific, and in 13% of patients distant metastases are discovered on diagnosis. The classic c...

The carcinoid syndrome describes the signs and symptoms associated with unregulated vasoactive hormone production by neuroendocrine tumors. Carcinoid tumors can be found anywhere throughout the body, but these will not result in carcinoid syndrome unless they form in the liver as a primary tumor or as a metastasis. Symptoms of carcinoid syndrome include flushing, diarrhea, and wheezing. VIPomas...

Carcinoid tumors are rare, slow-growing neuroendocrine neoplasms that are often indolent and may not become clinically apparent until there is a metastatic spread or evidence of carcinoid syndrome. A 44-year-old man presented to our clinic department with a history of previous left colon cancer operation, chronic crampy left lower quadrant pain, mass and severe anemia. A MR scan was obtained wh...

BACKGROUND Bronchial carcinoid tumors are known as low-grade malignancies. Surgery has been proposed as the best treatment of choice for lung carcinoids. However, less invasive treatment approaches may be considered due to low-grade malignancy potential of such tumors. The aim of this study was to review the results of endobronchial treatments of carcinoid tumors of the lung and to compare with...

PATIENT Female, 67. FINAL DIAGNOSIS Pulmonary carcinoid tumor. SYMPTOMS Abnormal shadow on chest X-ray. MEDICATION -. CLINICAL PROCEDURE -. SPECIALTY Pulmonology. OBJECTIVE Rare disease. BACKGROUND Although pulmonary carcinoid tumors are generally considered to represent a low-grade malignancy, atypical carcinoids are more aggressive than typical carcinoids, metastasizing more com...

RATIONALE Typical pulmonary carcinoid is a kind of low-grade malignancy neuroendocrine tumor. Cushing's syndrome is a very rare clinical feature of typical pulmonary carcinoid caused by hypercorticism. Complete tumor resection is the standard curative treatment for primary typical pulmonary carcinoid. However, our knowledge on the gene level of typical pulmonary carcinoid is limited. PATIENT ...

BACKGROUND Colorectal carcinoid tumors are often described as being low-grade malignant. The objective of the current study was to address the clinicopathological features and outcomes of patients with colorectal carcinoid tumors. METHODS A total of 63 patients with colorectal carcinoid tumors were identified and evaluated using surgical pathology files and medical records between January 200...
