Carcinoid tumors rarely originate in the urogenital system. We represent a unique case of primary renal carcinoid tumor which was initially diagnosed as renal cell cancer and 10 years later correctly diagnosed as metastatic renal carcinoid.

Endocrine pancreatic tumors are neuroendocrine neoplasms with malignant potential and give rise to varied clinical syndromes due to excessive secretion of multiple hormones. In this study 22 endocrine pancreatic tumors and 11 carcinoid tumors were examined for the expression of CD44 using a monoclonal antibody. CD44 gene activity of 11 endocrine pancreatic tumor tissues and five carcinoid tumor...

Received June 2007 Accepted September 2007 INTRODUCTION Carcinoid tumors frequently develop in the gastrointestinal tract and the respiratory system.(1) Those originating from the kidneys are exceptionally rare. Less than 45 cases of primary carcinoid tumors of the kidney have been reported in the English literature, so far.(2-4) We herein report another case of primary renal carcinoid tumor fo...

Carcinoid tumors are neuroendocrine tumors and most frequently occur within tissues derived from the embryonic gut. These tumors can occur in any organ but are very rare in the paratesticular region. We hereby report a case of paratesticular carcinoid in a 70-year-old male who, to the best of our knowledge, is the oldest patient reported so far in the world literature.

Carcinoid tumors are commonly found in the gastrointestinal tract and are rarely seen in the presacral/sacrococcygeal region. Moreover, such tumors at these sites are usually silent without associated carcinoid syndrome even if the tumor has metastasized. These tumors may arise in tailgut cysts or teratomas thereby suggesting their congenital origin.

Carcinoid tumors are uncommon, slow-growing neoplasms. These tumors are capable of secreting numerous bioactive substances, which results in significant potential challenges in the management of patients afflicted with carcinoid syndrome. Over the past two decades, both surgical and medical therapeutic options have broadened, resulting in improved outcomes. The pathophysiology, clinical signs a...

Background: Carcinoids make nearly 2% of all lung tumors, and the typical carcinoid are more frequent than atypical (AC). Case presentation: We report a histologically confirmed AC case 23-years old male patient; revealed by back chest pain as first presentation; after covid vaccination. Past medical history that patient had received covid-19 vaccine in days before presentation. Contrast-enhanc...

Carcinoid pulmonary tumors occur in the fourth to sixth decades of life. Usually, typical carcinoid arise a decade earlier when compared to atypical carcinoid (45 years and 55 years, respectively). Typical carcinoid tumors are the most common primary lung neoplasm in children and late adolescents, but there are less than 40 cases described in the literature. The clinical presentation is nonspec...

Strumal carcinoid develops in a germ cell tumor characterized by an intimate mixture of thyroid and carcinoid. Unlike other carcinoid tumors, most patients with strumal carcinoid have no symptoms of carcinoid syndrome; few are reported to cause severe constipation. We report a case of a 60-year-old female patient presenting with severe progressive constipation and painful defecation for last fe...
