Abstract
Mucocele is a benign lesion occurring in the buccal mucosa as a result of the rupture of a salivary gland duct and consequent outpouring of mucin into soft tissue. It is usually caused by a local trauma, although in many cases the etiology is uncertain. Mucocele is more commonly found in children and young adults, and the most frequent site is the lower inner portion of the lips. Fibroma, on the other hand, is a benign tumor of fibrous connective tissue that can be considered a reactionary connective tissue hyperplasia in response to trauma and irritation. They usually present hard consistency, are nodular and asymptomatic, with a similar color to the mucosa, sessile base, smooth surface, located in the buccal mucosa along the line of occlusion, tongue and lip mucosa. Conventional treatment for both lesions is conservative surgical excision. Recurrence rate is low for fibroma and high for oral mucoceles. This report presents a series of cases of mucocele and fibroma treated by surgical excision or enucleation and the respective follow-up routine in the dental clinic and discusses the features to be considered in order to distinguish these lesions from each other.
Highlights
Mucocele is a benign cystic lesion, asymptomatic, usually containing saliva in its interior, and caused by disruption of the ducts of minor salivary glands or the presence of calculus inside gland ducts
Oral mucoceles can alternatively be treated by the technique of filling the interior of the lesion by dental alginate followed by enucleation and micromarsupialization [7,9]

Summary
Mucocele is a benign cystic lesion, asymptomatic, usually containing saliva in its interior, and caused by disruption of the ducts of minor salivary glands or the presence of calculus (sialolith) inside gland ducts. Slightly bluish or translucent, present slow growth [4], and are more common among children and young adults. Some oral mucoceles involute and disappear spontaneously after a short time, while others are chronic and require surgical removal or marsupialization. Fibromas are asymptomatic lesions found more frequently in the buccal mucosa, in the fourth decade of life. They present a smooth surface, nodular appearance, hard consistency and a sessile base. Oral mucoceles can alternatively be treated by the technique of filling the interior of the lesion by dental alginate followed by enucleation and micromarsupialization [7,9].
