MEDULLARY CARCINOMA OF THE THYROID METASTATIC TO THE TEMPORAL BONE

We report a case of proven thyroid medullary carcinoma, metastatic to the temporal bone. Review of the otolaryngology literature demonstrate s that this is the first such report. The patient presented with sympt oms, physical examination, and imaging studies suggestive of a glomus jugulare tumour. The pre-operative diagnosis of metastatic thyroid med ullary carcinoma, however; was made, based on a history of medullary c arcinoma of the thyroid with previous metastases as well as an elevati on in calcitonin levels. Histological examination of the surgical spec imen cofirmed the diagnosis.
