cells which are widely distributed in the body. The sites most often affected by these tumors, in order of importance, are the gastrointestinal and bronchopulmonary tracts (1). However, primary neuroendocrine tumors in the presacral region are extremely rare. Even though there were a few reports about neuroendocrine tumor of the presacral region, to the best of our knowledge, primary malignant ...
BACKGROUND The primary neuroendocrine tumors of the gallbladder are very rare, representing 0.2% of all neuroendocrine tumors. The definite diagnosis is incidental in most cases. CASE REPORT A 60-year-old male patient presented with a one-month history of epigastric pain and jaundice, itching, flushing, cough and wheezing.

We describe a rare hepatic collision tumor composed of a hepatocellular carcinoma and a high-grade neuroendocrine carcinoma. The patient, a 68-year-old man, underwent a partial hepatectomy because of a 4.0 cm mass. The tumor had two distinctive patterns. The majority of the tumor was a high-grade neuroendocrine carcinoma with features of a small cell carcinoma that was positive for chromogranin...

Primary hepatic carcinoid tumor is rare and poses a challenge for diagnosis and management. We presented a case of primary hepatic carcinoid tumor in a 53-year-old female with a complaint of right upper abdominal pain. Computer tomography scans revealed a hypervascular mass in segment 4 of the liver. An ultrasonography-guided biopsy showed a carcinoid tumor. No other lesions were found by the r...
The aim of this study was to assess the clinical sensitivities of the tumor markers chromogranin A (CgA), urinary 5-hydroxyindoleacetic acid (5-HIAA) and alkaline phosphatase (AP) in neuroendocrine tumors (NETs) of the GastroEnteroPancreatic-(GEP-) system depending on tumor primary location and metastatic spread. In a retrospective single-center series, sensitivities were evaluated in serum sam...
