Abstract
Papillary carcinoma of thyroid (PCT) is the most common type of thyroid malignancy and metastasis to cervical lymph nodes is very common [1]. Blood borne metastases from PCT are less frequent than with the other thyroid carcinomas [2]. Uncommon sites include lungs, bone, atrium, cerebrum, kidney, skin [3].
We report four cases of papillary carcinoma with uncommon sites of metastasis.
One showed tumor emboli of 2.5 cm in internal jugular vein, one had tumor deposit in metacarpal bone and lung, one had a subcutaneous tumor deposit and one was a micropapillary carcinoma with metastasis axillary nodes. All these four cases were classical PCT.
Keywords: Papillary carcinoma, Metastasis, Tumor thrombi, Internal jugular vein, Bone, Lung, Skin
