Obstructive congenital gingival granular cell tumour.

Congenital gingival granular cell tumours (CGCT) are rare and always benign intraoral tumours originating from the alveolar ridge. They are also known as congenital epulis, congenital myoblastoma or Neumann's tumour. They are typically seen as a mass protruding out of a newborn child's mouth. In general, CGCT occurs as a solitary tumour. The main differential diagnosis is epignathus (oral teratoma). This report describes a newborn with a mass originating from lower alveolar ridge obtruding into the oral cavity. Clinical features, histiogenesis and necessity for early surgical treatment due to risk of airway obstruction and difficulty in feeding were discussed.
