A Rare Case of Intrathyroid Dermoid Cyst in a Middle-aged Female

Abstract

Introduction: The term ‘dermoid cyst’ describes a cystic lesion comprising of stratified squamous epithelium with epidermal
appendages. Presentation of case: A dermoid cyst arising in the left lobe of the thyroid gland in a 35-year-old female
was managed with a left hemithyroidectomy. Discussion: While congenital lesions feature frequently in the differential
diagnosis of childhood neck masses, dermoid cysts presenting as a unilateral neck mass are rare. Conclusion: When dermoid
cysts are found within the thyroid, their pathogenesis may be explained by a disruption of normal thyroid development.
Excision appears the treatment of choice.
