title: Struma salpingis associated with struma ovarii.
abstract: We report a case of a struma salpingis, a benign teratoma consisting entirely of thyroid tissue in the fallopian tube. This 0.2-cm tumor was an incidental finding in a 44-year-old, clinically euthyroid, woman. The ipsilateral ovary showed a 0.1-cm struma ovarii, and there was a 7.0-cm mucinous cystadenoma of the contralateral ovary. To our knowledge, this is the second report of struma salpingis and the first account of concurrent thyroid tissue in both the tube and ovary. Struma salpingis probably arises from germ cells arrested in their migratory path towards the genital crest.
