title: [Heterotopic thyroid tissue localized to the pelvis].
abstract: A case of well encapsulated thyroid tissue localized to the pelvis and without relation to the ovaries is presented. This anomaly is interpreted as a monodermal extragonadal teratoma. In cases of unusual localization of thyroid tissue, the following should be considered in the differential diagnosis: ectopia, metastasis from an occult carcinoma of the thyroid gland and teratoma. When thyroid tissue of teratoid origin is found, surgical removal is advised on account of the malignant potentialities of these tumors.
