Sub-Lingual Implantation Keratinized Epidermoid Cyst Masquerading as Plunging Ranula: Report of a Rare Case with Literature Review.

Sublingual epidermoid cysts are rare benign lesions derived from ectodermal tissue, typically located beneath the tongue or the floor of the mouth. While often asymptomatic, these cysts can grow and cause discomfort or complications, making accurate diagnosis and appropriate treatment crucial. We present the case of a 6-year-old Indian girl diagnosed with an implantation keratinized sublingual epidermoid cyst, initially misidentified as a plunging ranula.
