[Atypical metastases disclosing vesicular carcinoma of the thyroid].

Differentiated carcinoma of the thyroid may generate bone or lung metastases. Some times, thyroid cancer remains latent, and is revealed by the presence of secondary bone tumors. In the present paper, we relate our personal experiences with two patients who had thyroid cancer diagnosed indirectly through the occurrence of distant metastases. The secondary tumors were localized in the right frontal sinus and the cranial vault, respectively. We discuss the diagnostic and therapeutic problems involved with such metastases. We further present a review of the literature dealing with this topic.
