Sonographic detection of a lingual node metastasis from early squamous cell cancer of the tongue.

Lingual node metastasis from early-stage squamous cell carcinoma of the tongue is uncommon and difficult to detect. We present a case of a lingual lymph node metastasis from an early tongue cancer. Sonography demonstrated a small nonpalpable lingual node on the floor of the mouth. The patient underwent complete surgical resection and had no evidence of recurrence 5 years later. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 46:69-72, 2018.
