Dermoid cysts are benign lesions that rarely occur in the floor of the mouth. They can be divided in epidermoid, dermoid and teratoid cysts. In this report the case is presented of a 17 year old female patient with a painful swelling in the left submandibular area. After extensive diagnostics, repeatedly performed cytologic puncture pointed towards a dermoid cyst. The diagnosis epidermoid cyst was made postoperatively, by histologic examination of the surgically removed lesion.Although the final diagnosis of an epidermoid cyst is made by histologic examination, additional imaging is of great importance for preoperative knowledge of size, character, localization and relation to surrounding structures of the lesion.Despite (epi) dermoid cysts being relatively uncommon in the head and neck region, this case as well as case reports in literature show that a swelling located in the neck can be caused by an (epi) dermoid cyst.
