The majority of mucoceles originate from minor salivary glands. The most importantreason is lip or cheek biting habit, which can lead to trauma, and saliva leakage from the damaged canal intothe adjacent connective tissue. In this case report, a 10-year-old girl patient with mucocele is presented, anddiscussed its' etiology.
