A 28-year-old woman presented with a lump in her neck. She had noticed the lump 6 months earlier but had not been experiencing any pain or tenderness. She denied any history of hoarseness, difficulty in swallowing, double vision, or weight loss. She stated that the mass had not enlarged and that there was no drainage from it. She also denied using tobacco or alcohol. Physical examination revealed a hard 3.0×2.5-cm mass on the right side of the neck, located between the angle of the mandible and the sternocleidomastoid muscle. The mass did not show any signs of inflammation or pulsation, but palpation revealed that it was only partially mobile. The patient did not feel any tingling or spiking sensation during palpation of the mass. Her otorhinolaryngological examination revealed no other abnormalities.
