Case Report - Isolated submandibular gland metastasis from an occult papillary thyroid cancer

A case of an isolated submandibular gland metastasis from a clinically occult papillary thyroid carcinoma is described in a 46-year old lady. Initial surgery was done based on the fine needle aspiration cytology (FNAC) report of adenocarcinoma of the submandibular gland. Histopathologic examination of the specimen suggested a metastatic papillary carcinoma. Occult papillary carcinoma in the thyroid was found by multiple blind FNACs. Subsequently to near-total thyroidectomy, no other site of metastasis was found on radio-iodine scanning.
