ABSTRACT
Metastatic lesions represent up to 3% of malignant tumors of the thyroid
gland. Most cases originate from lung and renal cell tumors. The diagnostic approach
implies a high clinical suspicion in patients with known primaries, however,
it can be the initial manifestation of an extensive undiagnosed malignant disease
in up to 20% to 40% of patients. Fine-needle biopsy has shown good performance
for the diagnosis of metastatic nodules. The prognosis and the option of surgical
treatment depend on the local control of the primary condition and the state of the
associated systemic disease, therefore it must be individualized. In general, up to
80% of patients with thyroid involvement have multi-organ metastatic disease and
surgical treatment is intended to be palliative to prevent complications resulting
from local extension of the disease to structures of the upper aerodigestive tract in
the neck. A case series of six patients with metastatic lesions to the thyroid gland
with primaries in the kidney, breast and melanomas is presented below.
