ABSTRACT
Salivary duct cyst (SDC) in an uncommon lesion of the minor salivary glands, with etiology related to obstruction of the salivary duct. It presents with a color similar to that of the mucosa, is mobile, measures between 3 and 10 mm and affects preferentially the bottom lip, fl oor of the mouth and the jugal mucosa. SDC have a predilection for the male and individual in elderly groups. The pathogenesis of SDC is associated with the formation of a mucous plug that causes partial or total obstruction of the salivary gland system duct, resulting in the dilation of the duct and increase in intraluminal pressure. They present clinical-pathological characteristics similar to those of salivary gland tumors, making diagnosis diffi cult and subject to errors in treatment. It is important for the dentist to include SDC in the differential diagnosis of lesions that affect the upper lip, although it is relatively rarely found in this anatomic site.
ABSTRACT
The salivary duct cyst is a rare disease and usually found in the parotid gland. A 55-years-old man presented swelling in the left buccal area and pathological diagnosis was a salivary duct cyst. Though its recurrence has been reported rare, the presented case showed recurrent swelling after enucleation. The recurrent lesion was successfully treated by incision and drain insertion.
