The patient, an 11-year-old white boy, presented with an asymptomatic cervical nodule that was present from birth. The patient and his parents desired removal of this nodule for both cosmetic reasons and prevention of injury when competing in athletic events. The child was otherwise healthy with no other history of medical problems or malformations. The nodule was located anterior to the insertion of the left sternocleidomastoid muscle at the sternoclavicular joint (Fig 1). It was approximately 1 cm in diameter, smooth surfaced, fairly movable, and firm but with a "springy" consistency, like cartilage. The nodule appeared to lie predominantly in the subcutaneous fat, and its lateral extent could be palpated by pinching it between the thumb and index finger. The overlying skin was normal, but a minute dimple could be seen overlying the lesion when the skin was pinched together.
