Abstract

An oral foregut cyst is a rare congenital choristoma lined by the respiratory and/or gastrointestinal epithelium. The exact etiology has not been fully identified, but it is thought to arise from misplaced primitive foregut. This lesion develops asymptomatically but sometimes causes difficulty in swallowing and pronunciation depending on its size. Thus, the first choice of treatment is surgical excision. Surgeons associated with head and neck pathology should include the oral foregut cyst in the differential diagnosis for ranula, dermoid cyst, thyroglossal duct cyst and lymphangioma in cases of pediatric head and neck lesions.

Figure

• 

  Fig. 1 Magnetic resonance (MR) images. A. Coronal MR image showed a low attenuated on T1-weighted in the ventral tongue. B. A high attenuated on T2-weighted. Thus, we could concluded this lesion is consisted with fluid accumulation.

• 

  Fig. 2 The cystic mass was dissected and removed (oval shaped with 2 cm diameter).

• 

  Fig. 3 A. Ciliated columnar epithelium was seen (H&E staining, ×200). B. Goblet cell responded positively to a periodic acid Schiff (PAS) staining (×400).
