Abstract

Ectopic thyroid tissue is an uncommon abnormality. Most reported cases were in midline or near midline without thyroid gland in its normal position. Few cases were reported as lateral ectopic thyroid tissue without normally located thyroid tissue BUT Lateral ectopic thyroid tissue with normally functioning and positioning thyroid gland is extremely rare. We present a 60 years old female patient complaining of 5 months history of left submandibular mass. NO risk factors of malignancy. It was diagnosed as a case of submandibular lymph node or minor salivary gland tumor. CT SCAN with contrast showed well defined rounded lobulated mass immediately inferior and not continuous to left submandibular gland. Excisional biopsy was done. Histopathology report came as a benign thyroid tissue with lymphocytic thyroiditis background. This is a rare case of left sequestered submandibular thyroid nodule. Lateral thyroid ectopias reflect difficulties in diagnosis and management.
