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...

Carcinoid tumors of the rectum are uncommon tumors [1]. However, recent report shows that the number of reported cases increases rapidly in both Japanese and non-Japanese series [2], probably due to the constant increase number of colonoscopic examination. The rectum is the most common site of gastrointestinal carcinoid tumors in Japan and the third most common site in American-European countri...

Purpose: We report an unusual case of trabecular carcinoid of the ovary with orbital involvement. Methods: We encountered a 49-year-old woman with a complaint of bilateral proptosis. Ocular examination revealed severe bilateral proptosis and signs of corneal exposure. Orbital CT scan showed massive enlargement of extraocular muscles and optic nerve compression. The patient medical history showe...

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...

Carcinoid syndrome is the constellation of symptoms mediated by humoral factors produced by some carcinoid tumors. It consists primarily of vasomotor symptoms, gastrointestinal hypermotility, hypotension, and bronchospasm, due to the production and release of vasoactive substances. Carcinoid heart disease occurs in more than 50% of patients with carcinoid syndrome; in some cases, it represents ...

Carcinoid is a neuroendocrine neoplasm derived from primitive stem cells, occurring most frequently in the alimentary tract. Somatostatin-receptor scintigraphy with indium-111 pentetreotide is a sensitive and noninvasive technique for imaging carcinoid and its metastatic spread. However, nontumoral lesions such as sarcoidosis may also express somatostatin receptors, which may present a diagnost...

BACKGROUND Carcinoid tumors represent an unusual and complex disease spectrum with protean clinical manifestations. This compilation of several large United States-based databases comprising patients from 1950 to 1999 examines 13,715 carcinoid tumors and provides epidemiologic information regarding the natural history and evolution of the detection and diagnosis of this entity. METHODS The au...

Carcinoid tumors are rare, arising in 1.2-2.1 per 100,000 people in the general population per year.1 In 20%-30% of patients, the initial presentation occurs as a result of peptide production, ie, carcinoid syndrome. The malignant carcinoid syndrome consists of flushing, gastrointestinal hypermotility (secretory diarrhea), bronchospasm, and carcinoid heart disease. The syndrome is caused by the...

Metastasis to the breast is a rare occurrence, constituting fewer than 2% of all breast tumours. Of all metastatic tumours in the breast, most arise from contralateral breast primaries. Other reported primary solid tumour sites include melanoma; lung, gastric, and renal cancers; and approximately 29 cases of carcinoid tumour.Ambiguous presentations and an absence of carcinoid syndrome features ...
