A rare case of paediatric sublingual keratinous cyst

Abstract

The occurrence of keratinous cyst in the oral cavity is extremely rare. Keratinous cyst in the floor of the mouth is painless, doughy or fluctuant lesion and causes no symptoms until it is large enough to interfere with speech or eating. Cyst generally presents as slow and progressive growth and often not diagnosed until the second or third decade of life.We report an uncommon presentation of keratinous cyst of the sublingual space in a 6year old female child. The swelling was mimicking ranula on inspection. On complete examination, the swelling appeared as epidermoid cyst. After a routine evaluation of the sublingual mass, surgical excision was performed under general anaesthesia. This case report addresses novel information regarding simple yet effective way of managing a sublingual keratinous cyst in a paediatric patient.
