Multiple genital tract tumors and mucinous adenocarcinoma of colon in a woman with Peutz-Jeghers syndrome: a case report and review of literatures.

We report a very rare case of Peutz-Jeghers syndrome (PJS) composed of multiple genital tract tumors and mucinous adenocarcinoma. A 46-year-old woman presented to our hospital with lower abdominal pain resulting from PJS involves sex cord tumor with annular tubules (SCTAT), ovarian mucinous tumor, ovarian serous tumor, mucinous adenocarcinoma of colon. The CEA concentration is high before surgery, and decreases after the surgery and subsequent chemoradiotherapy. This case demonstrates a classic clinical presentation of a patient with PJS. PJS patients have increased risk of malignancy and early detection and regular surveillance of the high-risk patients with PJS is crucial. Surgery may be required for obstructive gastrointestinal lesions as well as those exhibiting malignant degeneration.
