Abstract

Carcinoid tumors of the ovary are rare, comprising about 0.1 percent of all ovarian neoplasms, and account for less than 1 percent of all carcinoids in the body. Since the first two cases of ovarian carcinoid were described in 1939 by Stewart et a1., both primary and less often metastatic forms have been accumulated in the literature. The most common is primary in the ovary, growing in an insular pattern, typically observed in carcinoids arising in the midgut derivatives ; around 70 cases of this type have been documented in the world literature. Less often ovarian carcinoids of trabecular pattern observed in carcinoids arising in the foregut and the hindgut derivatives have been described. There also have been some reported cases of struma carcinoid of the ovary. Most primary ovarian carcinoids are associated with benign cystic teratomas, but some occur in apparently pure form. To our best knowledge, there has been no single proven case of primary ovarian carcinoid in the Korean literature. Authors are to describe a histochemically and ultra-structurally proven case of a nonfunctioning primary ovarian carcinoid of insular pattern associated with an otherwise classical cystic teratoma in a 44 year-old Korean female patient. Clinical Summary ; A moderately developed and nourished 44 year-old Korean female patient was admitted to the Seoul National University Hospital in July 1974, complaining of dull lower abdominal pain of several months duration. Otherwise she had carried out healthy life. On admission body temperature was 36.8℃, pulse rate 76/min and blood pressure 140/90 mmHg. Auscultation of the chest and heart were normal. Pelvic and rectal examination revealed a double fist sized, doughy and movable right sided intrapelvic mass, and an ovarian cyst was suspected. Routine laboratory finding and chest X-ray film were unremarkable. Urinary 5-hydroxyindoleacetic acid was not determined, and evidence of flushing or diarrhea was not recorded. Operation was performed under the impression of ovarian cyst ; there was a large cystic mass on the site of right ovary but with no adhesion to the surrounding structures. Left ovary was grossly normal. Liver, peritoneal cavity and gastrointestinal tract were free. Hysterectomy and right salpingo-ooph-orectomy were carried out. Hospital course was uneventful and she was discharged at the 8th hospital day, and was lost thereafter for further follow up.
