The plunging ranula or cervical ranula is amucous extravasation cyst of the
sublingual gland. It is slightly common in females, shows no side preference, and is
more prevalent in the second and third decades of life. It typically manifests as a
painless, nonmobile swelling in the neck. The pathogenesis of plunging raunla is the
discontinuities of the mylohyoid muscle in a position that would allow extravasation of
sublingual gland mucin. The histologic appearance is characteristically of a cyst, devoid
of epithelium of epithelium or endothelium, with a vascular fibro-connective tissue wall
containing some chronic inflammatory cells and macrophages stuffed with mucin. The
correct diagnosis is essential for the most effective treatment, which is exicision of the
sublingual gland. The plunging ranula must be differentiated clinically and
histomorphologically from thyroglossal duct cyst, dermoid cyst, branchogenic cyst,
lymphangioma, laryngocele, lipoma, hemangioma, cervial thymic cyst, cysts of the
parathyroid or thyroid gland, lymphadenopathy, abscess, or tumor.
We report a case and review the literatures, in our case, 23-year old man were
diagnosis as plunging ranula after have been taken sialogam, MRI, etc. He underwent
surgery via a cervical approach. The ranula reached the anterior neck by passing
through a dehiscence in the mylohyoid muscle. A pseudocyst was extirpated. Although
total rior neck by passing through a dehiscence in the mylohyoid muscle. A pseudocyst
was extirpated. Although total sublingual gland excision was not performed, no
recurrence was observed during 6 months follow-up periods.
