Solitary Metacarpophalangeal Metastasis from Poorly Differentiated Thyroid Carcinoma: Excellent Tumor Marker and Scan Response to Two Fractions of Radioiodine Therapy.

ABSTRACT

Rare solitary metacarpophalangeal skeletal metastasis from poorly differentiated carcinoma of thyroid is reported in this communication. The case demonstrated excellent tumor marker and scan response to two fractions of radioiodine therapy (serum thyroglobulin 0.01 ng/ml at the time of the 3rd follow-up) and is being presently followed up on levothyroxine suppression.
