Carcinoid is a rare tumor originating from neuroendocrine cells, which are generally localized in the gastrointestinal tract. It has an annual incidence of 1.5 persons per 100 000. Usually, only carcinoid tumors that invade the liver result in pathological changes to the heart. The cardiac manifestations are caused by paraneoplastic effects of vasoactive substances such as serotonin, bradykinin...

This case report describes for the first time a case of pure testicular carcinoid pre-aortic lymph node metastases in a 25 year old patient with carcinoid syndrome. The simultaneous occurrence of intratubular germ cell neoplasia in the surrounding testicular tissue was identified by OCT4 and placental-like alkaline phosphatase positivity. This confirmed that the tumour had a germ cell origin in...

Carcinoid heart disease is classically described as right-sided valvular pathology. Solid cardiac metastases from carcinoid tumors are seldom reported. A multimodality imaging approach is needed to diagnose and localize this disease. Biopsy remains the gold standard to confirm the diagnosis of carcinoid. Octreotide uptake is characteristic of carcinoid tumor but not myxoma; thus, an indium-111 ...

Carcinoid tumor is a slow-growing type of neuroendocrine tumor, originating in the enterochromaffin cells and secreting mainly serotonin. Neuroendocrine tumors (NETs) are found throughout the intestinal tract, the appendix and terminal ileum being the most common locations, and are classified by site of origin and by degree of differentiation, with well-differentiated lesions representing those...

Rectal carcinoids comprise 12.6% of all carcinoid tumors and represent the third largest group of the gut carcinoids. A 64-year-old woman was diagnosed as high-grade neuroendocrine carcinoma. She had liver, bone, and bone marrow metastasis. Carcinoid syndrome was diagnosed due to diarrhea, nausea, vomiting, tachycardia, and high level of 24-hour urinary 5-hydroxyindoleacetic acid (160 mg/24 hou...

BACKGROUND: 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 70-year –old male with a complaint of right upper abdominal pain. Computer tomography scans revealed a hyper vascular mass in segment 5, 6th and 8 of the liver. An ultrasonography –guided biopsy showed a carcinoid tumor.No other lesi...

Primary carcinoid tumors of the ovary account for 5% of ovarian teratomas. They are frequently components of mature cystic teratomas or, less commonly, mucinous cystadenomas. Most tumors are seen in peri- or postmenopausal women with symptoms of enlarging mass, or are incidental findings. Microscopically, there are four major variants of ovarian teratomas of carcinoid type: insular, trabecular,...
