BACKGROUND/AIMS Rectal carcinoid tumors can be resected with endoscopy, and it is important to assess their prognostic factors. We evaluated the potential of Ki-67 expression as a prognostic factor in rectal carcinoid tumors. METHODS We retrospectively reviewed the medical records of 37 patients with rectal carcinoid tumors who got endoscopic resection from January 2001 to January 2011 at Inj...

Neuroendocrine neoplasms of the larynx encompass five separate tumors: paraganglioma, typical carcinoid, atypical carcinoid, small cell carcinoma, and large cell neuroendocrine carcinoma. Many synonyms are employed, with well-, moderately, and poorly differentiated neuroendocrine carcinoma commonly applied to the middle three tumors (World Health Organization preferred terminology). Paraganglio...

PURPOSE Metastatic neuroendocrine tumors secrete serotonin and other vasoactive substances that are responsible for carcinoid syndrome and carcinoid heart disease. We sought to evaluate the discriminatory utility of diagnostic biomarkers in determining the presence and severity of carcinoid heart disease in patients with metastatic neuroendocrine tumors. PATIENTS AND METHODS A cross-sectional...

Neuroendocrine tumors are rare tumors primarily located in the gastrointestinal tract. Goblet cell carcinoid is a rare subgroup of neuroendocrine tumors located in the appendix. Neurofibromatosis type 1 is an autosomal dominant disorder caused by a mutation in the NF1 gene. Patients with neurofibromatosis type 1 have an increased incidence of typical neuroendocrine tumors, but it is unknown if ...
