tumor, which is occasionally found during screening colonoscopy. Tumors less than 1 cm in diameter and limited in depth to the submucosal layer can be managed by endoscopic treatment, several types of which have been reported for rectal carcinoid tumor [1,2]. Because carcinoid tumor extends to the submucosal layer, simple endoscopic mucosal resection (EMR) will often leave tumor involvement in ...

Carcinoid tumor is one of the commonly encountered primary pulmonary neoplasms. Although it has been known to be accompanied by calcification and/or ossification, presentation with a large ossified mass is rare. We describe here the case of a 29-year-old female with the radiological finding of a single bony nodular lesion. Pathological examination of the surgically resected specimen led to the ...

Carcinoid tumors are relatively rare neuroendocrine malignancies most commonly originating from enterochromaffin cells in the gastrointestinal tract. The incidence is 1 in 100 000 of the general population.1 They usually grow slowly over years, commonly causing no symptoms at all until they become large or have metastasized. Carcinoid tumors of midgut origin may secrete large amounts of vasoact...

Carcinoid tumors are rare but diverse group of malignancies that arise from neuroendocrine cells. Skeletal muscle metastasis is exceedingly rare and is associated with a poor prognosis. We report a case of carcinoid tumor of the ileocecal with skeletal muscle metastasis. We also review available case reports of carcinoid tumors metastasizing to the muscle.

Thymic carcinoid tumors belong to the group of mediastinal tumors, but are quite rare and usually carry a very poor prognosis. This report illustrates a case in which a thymic carcinoid tumor that had led to cavernous sinus syndrome was treated successfully. This is the first case report of a thymic carcinoid to metastasize to the cavernous sinus.

The author investigated clinicopathologic features of 13 cases of carcinoid tumor in the digestive organs. The 13 cases of carcinoid were identified from 18,267 pathological specimens of digestive organs in the last 10 years in our pathology laboratory. The tumor locations were rectum in 9 cases, duodenum in 2 cases, liver in 1 case, and stomach in 1 case. The age of the patients ranged from 52...
