Infected dermoid cyst of the tongue with a sinus tract to the submental skin

Summary 

Objectives: We report a case of a teratoid type dermoid cyst of the tongue with a sinus tract to the submental skin. Study design: Case report. Methods: We present a 3-month-old infant with a dermoid cyst of the tongue with a sinus tract to the submental skin and review of the literature on dermoid cysts of the tongue. Results: This rare case presented as an enlarging tongue mass and difficulty feeding. A midline submental skin pinpoint discharge revealed to be a sinus tract connecting the cyst to the skin. Complete excision of the cyst and sinus tract through midline ventral tongue and submental incisions was performed. Conclusion: Although dermoid cysts of the tongue are rare they should be part of the differential diagnosis of tongue masses and presence of a sinus tract should be considered in such cases.
