Multiple primary neoplasms. Ovarian carcinoid tumor, mucinous cystadenoma of low malignant potential tumor of left ovary, and adenocarcinoma of the colon.

Abstract

We describe a case of primary left ovarian carcinoid tumor with metastases to the right paraovarian tissue, left fallopian tube, the right lung, omentum, cul-de-sac, pericolonic fat, and, most likely, metastasis to the contralateral ovary, as well as a simultaneous left ovarian mucinous cystadenoma of low malignant potential and a well-differentiated colonic adenocarcinoma. Primary ovarian carcinoids are almost always unilateral. Metastases from such tumors to the lung and adrenal gland are very rare. To our knowledge, no such combination of all the above tumors has been reported.
