Sadath M, Al Amadi A, Busafared FA, Alshaiba AA, Idnani DD. Dermoid cyst presenting as a submental swelling, causing diagnostic confusion. J Case Rep Images Otolaryngol 2023;4(2):6–9.ABSTRACT
Dermoid cyst is a benign cutaneous developmental anomaly that arises from the entrapment of ectodermal elements commonly arising from midline where the embryonic structures fuse. It is lined by stratified squamous epithelium with mature skin appendages found on their wall and their lumens filled with keratin and hair. Dermoid cysts usually form in the ovary, testes, the skin of the head, neck, face, or lower back, or in the central nervous system. Rarely dermoid cyst can occur on the lateral part of the neck or floor of the mouth. Neck swellings are difficult to diagnose clinically and are close to vital structures. Radiological investigations will help in diagnosis, but it is not confirmatory. We report a case of a 9-year-old girl who attended our institution with a right-sided neck swelling that had been present for five years and had an occasional history of pain. Examination of neck showed submental swelling above the hyoid, toward the right side, 3 × 4 cm, soft cystic, nontender, moving with deglutition and protrusion of tongue. Intraorally, the swelling was not visible, but it was bimanually palpable. Treated surgically and excision biopsy reported as a dermoid cyst. In the present article we report this rare mode of presentation of a dermoid cyst with a diagnostic confusion and a surgical challenge.
