Testicular neuroendocrine tumors (NET) or carcinoid tumors are rare neoplasms which represent 1% of all testicular tumors and can be divided into 3 subgroups: pure primary testicular NET, primary testicular NET associated with a teratoma, and NET metastases to the testis. We report an unusual presentation of a primary testicular neuroendocrine tumor in a 39-year-old male who presented after a p...

BACKGROUND Carcinoid tumors are characteristically low grade malignant neoplasms with neuroendocrine differentiation that arise in various body sites, most commonly the lung and gastrointestinal tract, but less frequently the kidneys, breasts, ovaries, testes, prostate and other locations. We report a case of a carcinoid of renal origin with synchronous single liver metastases on radiological s...

Introduction: Pheochromocytomas are catecholamine-producing neuroendocrine tumors that arise from the adrenal medulla. typically present with uncontrollable or paroxysmal hypertension can be accompanied by other common initial symptoms, including headache, diaphoresis, arrhythmia, and pallor. Given morbidity mortality associated undiagnosed pheochromocytomas, their potential for treatment, prim...

The liver is a common site for primary or metastatic disease. In addition to primary liver tumors, such as hepatocellular carcinoma, cholangiocarcinoma, and gallbladder carcinoma, several cancers are known to present with isolated hepatic metastasis, including colorectal carcinoma, ocular melanoma, and neuroendocrine cancers. Moreover, in patients with additional sites of extrahepatic disease, ...

BACKGROUND Presacral masses are unusual growths that have a limited differential diagnosis, typically not including neuroendocrine tumors (NETs). Classically, NETs are well-differentiated gastroenteropancreatic tumors of probable benign behavior. These tumors are associated with a typical morphologic pattern and involve the distal colon, rectum, and genitourinary tract; they are considered less...

Primary hepatic carcinoid tumors are extremely rare neoplasms derived from hormone-producing neuroendocrine cells. It is difficult to make their diagnosis before biopsy, surgical resection or necropsy. A recent publication described only 94 cases of these tumors. There is no sex predilection and apparently it has no association with cirrhosis or preexisting hepatic disease. The most effective t...

We report a case of mixed adenoneuroendocrine carcinoma (MANEC) of stomach with tubular adenoma and well-differentiated neuroendocrine tumor (WD-NET) in the primary tumor in the stomach giving rise to biphenotypic regional nodal metastases. A 35-year-old woman with abdominal pain was found to have a 1.8-cm gastric lesion, diagnosed as WD-NET (intermediate grade) on the biopsy. The resection spe...

INTRODUCTION A neuroendocrine tumor has known as a neuroendocrine system tumor. Rarely, neuroendocrines have found in other areas, like the liver, gallbladder, bile ducts, kidneys, ovaries or testicles. CASE PRESENTATION We have a 41-year-old woman has referred to our medical center, complaining of fullness and vague pain on her right upper quadrant. The liver scan, sonography, MRI demonstrat...
