title: Extravasation mucocele involving the ventral surface of the tongue (glands of Blandin-Nuhn).
abstract: BACKGROUND
  Mucocele is a lesion that involves the salivary glands and respective current ducts caused mainly by traumas in the affected area. Two different histological forms can be found: extravasation phenomenon and mucus-retention cyst where the former is the most frequently observed involving minor salivary glands such as the glands present in the anterior portion of the ventral surface of the tongue (glands of Blandin-Nuhn).
  
  
  METHODS
  This report describes a large lesion involving the ventral surface of the tongue that was definitively diagnosed by histological examination as extravasation mucocele.
  
  
  CONCLUSIONS
  Important concepts are reviewed to help clinicians correctly diagnose and treat this pathology.
