A 55-year-old female patient came to surgical outpatient clinic with complaint of gradual increasing painless swelling of the floor of the mouth and submental region under the tongue and beneath the chin with difficulty in speech and swallowing for 6 months of duration. No history of trauma, operation, or prolonged fever was present. She was nondiabetic, nonhypertensive and had no history of tuberculosis or chronic illness. On clinical examination, her vitals were within normal limit. Central nervous system, cardiovascular, and chest and abdominal examination revealed no abnormality. Local examination revealed cystic, nonpulsatile, noncompressible, nontender, and nontranslucent sublingual and submental swellings [Figure 1a and b]. The submental swelling was not moving with tongue protrusion. No sign of inflammation was present. No transmitted pulsation over the sublingual swelling was felt during compression of submental swelling and vice versa. Clinical diagnosis was plunging ranula or dermoid/epidermoid cyst. Ultrasound examination of the sublingual swelling showed cystic swelling with uniform low-level echogenicity, internal particulate content with no internal vascularity on the color Doppler study [Figure 1d]. The submental lesion revealed particulate internal content with multiple floating echogenic lobules (like stalk of marble) inside the cystic swelling with no posterior acoustic shadow and no evidence of internal vascularity on color Doppler study [Figure 1c]. Noncontrast-enhanced computed tomography (CT) of the face shows hypodense cystic lesion in the sublingual and submental region [Figure 2a]. Magnetic resonance imaging of the face revealed two separate sublingual and submental cystic lesions showing T1-weighted hyperintense, T2-weighted/short tau inversion recovery (STIR) hyperintense signal and diffusion restriction in diffusion weighted image (DWI), and apparent diffusion coefficient (ADC) sequences [Figure 2b-f]. The submental swelling shows T1-/T2-weighted hypointense discrete nodular structures within the fluid content. No fat signal was seen within the both swellings. Radiological diagnosis was sublingual and submental epidermoid cysts. She was operated under general anesthesia. Both cystic lesions were enucleated by intraoral sublingual dissection with intact capsules, and the opening in the floor of the mouth was marsupialized [Figure 3a-c]. The sublingual cyst was below the floor of mouth mucosa and the submental cyst was between genioglossus muscles. The cystic lesions were pearly white and revealed epidermoid cyst on histopathological examination [Figure 4a and b]. The echogenic nodules of submental lesion in ultrasonography (USG) study were keratin accumulation. Her postoperative period was uneventful. She was advised for 6 monthly follow-up for 2 years. No recurrence was seen during 18 months of postoperative follow-up.
