A woman in her 30s presented with a 1-year medical history of a painless, slowly enlarging, midline neck mass without associated dysphagia, odynophagia, weight loss, or history of infection. The mass was soft, mobile, and compressible in midline level IA, measuring 7 cm and posterior-superiorly displacing the tongue. The mass was visible as a clear blue lesion in the floor of the mouth and was nontender. Computed tomographic (CT) scan of the neck with IV contrast was performed (Figure). The patient was taken to the operating room for a successful combined intraoral and transcervical approach to excision.
