“…To our knowledge, only nine cases of rectal carcinoid, including the present case, have been reported [4][5][6][7][8][9] . Frequencies of the pedunculated type in rectal carcinoids were reported to be 2.4 % to 7.1 % in the literature [5,6] . Because of its rarity, pedunculated configuration may confuse the endoscopic diagnosis of carcinoids.…”

Carcinoid tumors generally appear as yellow/gray or tan submucosal nodules. We experienced a case of pedunculated rectal carcinoid showing a mushroom-like appearance. The case was a forty years old woman who was admitted to our hospital due to rectal bleeding. Colonoscopy revealed a pedunculated polyp presenting a mushroom-shaped appearance measuring 13 mm in diameter in the rectum. The histological diagnosis of specimens obtained by biopsy was adenocarcinoma and transanal ultrasonography revealed the tumor localization within the submucosal layer in the rectum. Endoscopic mucosal resection (EMR) was performed. Histopathological examination established the diagnosis of carcinoid tumor in the rectum. Frequencies of the pedunculated type in rectal carcinoids were reported to be 2.4 % to 7.1 % in the literature. Because of its rarity, pedunculated configuration may confuse the endoscopic diagnosis of carcinoids. Treatment for carcinoids of 1 to 1.5 cm in size remains controversial. Although such tumors are technically respectable by EMR, careful attention must be paid in dealing with these tumors because there may be unexpected behaviors of the tumors.

“…In this regard, early detection is necessary to improve prognosis. In addition, preoperative information on tumor extent is useful for surgeons in deciding whether a radical operation or local excision is necessary [11,13].…”

Radiographs of 12 carcinoid tumors of the rectum were reviewed and compared with pathologic findings. There was a good correlation between the radiologic and pathologic findings with respect to tumor invasion and extent. Nine tumors that radiologically presented a smooth round defect less than 2.0 cm in diameter did not invade the muscular layer and did not metastasize. Three tumors that presented a deep crater with an irregular edge greater than 2.0 cm were found to have invaded the muscular layer and metastasized to the lymph nodes or the liver. The double-contrast enema showed an excellent detection rate; no lesion was missed by it.

Two thousand eight hundred thirty-seven cases of carcinoid tumor from files at the National Cancer Institute were analyzed statistically. Tumors were found in the lung, ovary, and biliary and gastrointestinal tracts. Most were in the appendix, rectum, and ileum. Age-adjusted incidence rates were higher for black males, except for lung carcinoids. Carcinoids showed several differences from other kinds of tumor, including a low age for appendiceal and lung cases and low male/female and black/white ratios in the lung. Percentages of concurrent neoplasms and multiple carcinoids were low compared to other series. Five-year relative survival rates ranged from 99% (appendix) to 33% (sigmoid colon). Survival for colon cases was not so low as expected on the basis of the high rate of metastasis. Some appendiceal carcinoids were metastatic and may have killed 1 patient. Findings are compared with other studies.
