title: Double tongues.
abstract: A 1-year-old Chinese boy presented with a mass at the base of his tongue with dysphagia. The distal end of the lesion could be put out of his mouth, making a "double tongue" appearance. Before surgery, serum test showed euthyroidism. Thyroid scintigraphy showed good function of the orthotopic thyroid, yet no uptake by the lesion, excluding ectopic thyroid. En bloc resection was performed. Histopathology demonstrated aberrant salivary tissues. Our case indicates that differential diagnosis between ectopic salivary tissues and ectopic thyroid should be borne in mind when treating patients with double tongues.
