Abstract

Papillary thyroid microcarcinoma (PTMC) is defined as being 1 cm or less in diameter. Although the prognosis of PTMC is known to be more favorable than that of papillary thyroid carcinoma greater than 1 cm in diameter, pathologic factors suggesting aggressiveness, such as multifocality and lymph node invasion, have been reported to be highly prevalent in PTMC. However, the rate of distant metastasis in patients with PTMC is very low. Many investigators have reported that initial distant metastasis was detected only in patients with PTMC greater than 0.4 cm in diameter, however these cases have involved only one organ, usually the lung. We report here on an extremely unusual case of solitary PTMC (0.3 cm in diameter) presenting multiple distant metastases at the time of diagnosis.

Keywords: Multiple distant metastases, Papillary thyroid microcarcinoma
