A 32-year-old white woman presented with a subcutaneous nodule on her neck. The lesion was first noticed by her parents when she was 8 years old. It had gradually increased in size proportionately to the patient's own growth, without any periods of progressively rapid enlargement. The patient denied any history of symptoms, infection, or other complications associated with the nodule, but she reported that the mass would swell at times, particularly after exercise. Subsequently, the lesion would express clear viscous material either spontaneously or after external squeezing. The patient was otherwise healthy.
