A 15-year-old boy presented with a mass in the left side of his neck that had been discovered incidentally several weeks earlier. The mass was not painful and had manifested no inflammatory features. The patient was in good health otherwise and had no additional constitutional symptoms. Physical examination revealed a subcutaneous, nontender, mobile mass measuring 2.0 × 1.5 cm at the posterior border of the left sternocleidomastoid muscle. The overlying skin was intact and normal in color and consistency. No additional cervical masses were palpated. The findings of the remainder of the otolaryngologic and systemic examinations were normal.
