case_images: On intra-oral examination, a massive swelling present in the floor of the mouth which measures about 5 * 5 cm raised the body of the tongue palatally [Figure 1a]. Extra-orally, it looks like a "double chin" in the mid-line, in which the swelling was firm and fluctuant extending up to the mylohyoid muscle [Figure 1b].

case_images: Using blunt dissection, the oral mucous membrane was freed up bilaterally to expose the mass beneath [Figure 3a]. The initial plan was to remove the cyst in toto, but because of its extent, the cyst was decapsulated intentionally and the white cheesy sebaceous keratinaceous material was evacuated, followed by removal of the capsule from underlying mucosa and muscular fibers [Figure 3b].
