Although lingual thyroid is the most common site for ectopic thyroid gland but carcinomas originating from lingual thyroid are extremely rare, accounting only for 1% of all ectopic thyroids. Here we represent a young female with a bleeding mass at the base of her tongue and review the diagnostic approach towards papillary thyroid carcinoma of lingual thyroid. The surgical treatment and follow up are discussed. A combination of radiological studies and histological evaluation should be deployed to investigate suspicious lingual thyroids. The perspective of diagnostic and therapeutic approaches for carcinomas of lingual thyroid is the same as orthotopic thyroid tissue.
