[Mucocele of the oral mucous membrane].

Mucoceles of the oral mucous membrane are benign tumoral diseases of the minor salivary glands of the oral mucous membrane. They most commonly occur in the labial mucosa. They can be caused by a break in the epithelium of the gland secreting saliva in the extra-glandular space and forming a pseudo cyst (extravasation mucoceles) or by a block in salivary flow due to an epithelial proliferation of the excretory duct forming salivary cyst (retention cyst). Various therapeutic approaches can be used. Traditional surgical resection is the most effective strategy with low recurrence rate. We here report a clinical case in order to give an update on this lesion. The patient involved in the study was treated in the Department of Dentistry and Oral Surgery, CCTD, Rabat, Morocco.
