A 24-year-old man presented with a 3-month history of a slowly enlarging mass in the left side of his neck. He was otherwise healthy and had no other symptoms. He denied any pain, hoarseness, difficulty breathing, paresthesias, or upper extremity weakness. He had no history of neck surgery. Physical examination revealed a large mass centered in the left posterior triangle. The mass was soft and compressible and felt to be deep to the subcutaneous layer of the skin. The patient did not experience any shooting pains with firm palpation of the mass.
