A 21-year-old female presented with a history of slowly enlarging nodular painless mass on the right side in the anterior part of the neck. The patient was asymptomatic except for cosmetic disfigurement. Thyroid function test results were within normal limits. On fine needle aspiration cytology, it was diagnosed as colloid nodule. A right hemithyroidectomy was performed in view of cosmetic disfigurement; histopathological examination of the excised specimen revealed ectopic thymic tissue adjacent to thyroid. This case is reported to emphasize the possible clinical and surgical presentation of this rare entity.
