BACKGROUND: The @entity61519 is defined as a cyst that originates by the separation of the follicle from around the crown of an unerupted tooth. The clinical examination reveals a missing tooth or teeth and possibly a @entity4 , sometimes resulting in @entity7439 and possible pathologic @entity174 . A large maxillary cyst involves the whole sinus and can transmit pressure to the walls of the sinus and, consequently, cause ophthalmologic and nasal symptoms to develop. OBJECTIVES: To report the case of an extensive @entity61519 with swelling of the right cheek, accompanied by @entity8968 . CASE REPORT: A 21-year-old @entity1 presented with swelling of the right cheek, right-sided @entity8968 , and watering of the right eye. Panoramic radiography revealed a relatively large and well-defined radiolucency enveloping an unerupted maxillary @entity235 tooth. Computed tomography scan showed a @entity5409 measuring 5.2 cm horizontally, 4.3 cm vertically, and 4 cm sagittally, with expansion and erosion of the anterosinus cortical bone. The mass was seen to extend into the right half of the nasal cavity up to the right ethmoid air cells, and was in contact with the base of the skull. The bony margins of the right maxillary antrum were thinned out, the osteomeatal complex was pushed medially-superiorly, and the pterygoid plates were intact. Excision of the @entity61519 of the right maxilla was performed using the Caldwell-Luc approach under general anesthesia. CONCLUSION: A @entity61519 arising from an unerupted tooth should be considered in the differential diagnosis of @entity735 , and @entity292 of the gingivobuccal sulcus.
