Аннотация
BACKGROUND: Primary ovarian carcinoid tumor is uncommon and represents less than 0.1% of ovarian malignancies. The strumal carcinoid may be complicated by carcinoid syndrome induced by peptide YY (PYY).
CASE REPORT: We describe a 45-year-old woman with a bilateral ovarian tumor diagnosed through periodical gynecological examination. She presented with severe constipation. Right ovarian cyst laparoscopically resected was diagnosed as a strumal carcinoid tumor; the left one was mature cystic teratoma. No metastatic findings were seen macroscopically on the ovarian surface and pelvic peritoneum. Constipation was drastically improved by resecting the tumor. The carcinoid tumor cells were positive for tumor-producing PYY by mRNA analysis.
CONCLUSION: It is important to be aware of this entity in the pathological diagnosis of ovarian tumors, in the presence of any clinical indicator of carcinoid tumor/syndrome, as it carries a markedly better prognosis and clinical outcome in comparison with most other malignant ovarian tumors.
