title: Serum thyroglobulin levels in patients with bone metastases from an unknown primary site.
abstract: Four cases with metastatic spread to bones and with primary site unknown are reported. The histopathologic examination on the bone biopsy material in 3 cases was adenocarcinoma. One case was suspected radiologically as primary bone tumor. The usefulness of estimation of serum thyroglobulin for detection of involved primary site is discussed.
