Abstract

Background: Mucoceles are self-limiting mucus-containing cavities that is caused by mechanical trauma to the excretory duct of the gland, which leads to pooling of saliva into the surrounding tissues. They may vary according to its clinical presentations, depending on its depth of involvement. They are usually asymptomatic. Sometimes they may show change in size due to rupture and subsequent mucin accumulation. They more frequently occur in relation to the lower lip.
Case Presentation: We present a case report of mucocele on the ventrolateral aspect of the tongue, which is a rare occurrence. Even though it clinically resembled a mucocele, diagnostic confirmation was done after histopathological examination.
Conclusion: Although surgical excision is the treatment of choice, removal of all the adjacent minor salivary glands is required to prevent the recurrence. They pose a diagnostic and therapeutic challenge to the clinician as well as surgeon due to its clinical resemblance with other lesions of the tongue. So, a thorough clinical knowledge as well as the determination of varying aspects of the etiopathogenesis of these oral lesions is necessary for correct diagnosis and for the indication of appropriate treatment.

Key words: Mucocele, extravasation cyst, retention cyst, case report.
