Abstract
Abstract This case report highlights our management of a large sublingual dermoid cyst. A fifteen-year-old Irish male presented with a swelling in the floor of mouth and displacement of the tongue. Speech changes were noted on presentation. A magnetic resonance imaging (MRI) scan revealed a 7 × 4 × 3 cm mass in the submental and sublingual spaces. Fine needle aspiration suggested a dermoid cyst. We excised the cyst via an intraoral approach. Sublingual dermoid cysts are rare entities, and their management has been poorly described. Our case report illustrates the value of an intraoral surgical approach.
Highlights
Dermoid cysts of the oral cavity most commonly occur in the midline floor of the mouth but can be displaced laterally or develop in other locations
Dermoid cysts are prevalent in the head and neck with a range of 1.6-6.9% and are extremely rare in the oral cavity, representing less than 0.01% of all oral cavity cysts [1,2,3,4,5]
Dermoid cysts are most commonly found in the ovaries and testacies. 7% of dermoid cysts occur in the head and neck, while 1.6% occurs in the mouth [15]
Summary
Dermoid cysts of the oral cavity most commonly occur in the midline floor of the mouth but can be displaced laterally or develop in other locations. A sudden increase in size has been reported during the onset of puberty due to an increase production of sebum from the sebaceous glands [8] They can displace the tongue, and patients may present with dysphagia, dysphonia, and dyspnea or when below the geniohyoid muscle, can produce a submental swelling or “double-chin” effect [9]. This ruled out a salivary and vascular pathology Cytological examination of this fluid demonstrated very occasional benign squamous epithelial cells together with proteinaceous material. These features were suggestive of a sublingual dermoid cyst.
