VERY often a patient with thyroid cancer goes first to an orthopedic unit with a fracture or a bony and soft tissue swelling. In some of these cases, the primary cancer in the thyroid is small and unassuming. Even when a palpable mass is present in the thyroid, it is difficult to establish the connection between the primary site and metastasis in the bone. In such cases no other investigation except a biopsy from the metastasis is helpful in suggesting the thyroid as a primary site of carcinoma.
We are presenting a case of metastasis from the thyroid cancer which presented several unusual features. In this patient the bony metastasis from thyroid cancer concentrated radioactive iodine avidly in spite of the fact that the thyroid gland was intact. The case history also illustrates the usefulness of radioactive iodine in diagnosis and treatment of metastasis from thyroid carcinoma.
