XXXX invading the orbit.

@entity1 @entity227 @entity41 @entity5 @entity1179 @entity9467 @entity1606 @entity8968
@entity1179 is an unusual entity for many ophthalmologists. We report a case of @entity1179 of the nasal cavity and sinuses, invading the orbit in a 33-year-old @entity1 . The @entity1 presented with a right medial canthal mass, proptosis, @entity227 , @entity9467 and @entity8968 . In the past, he underwent multiple procedures for surgical @entity5 with frequent recurrences. A computed tomographic scan revealed a mass filling both the nasal cavities and sinuses, destroying adjacent bones and invading the medial aspect of the orbit, leading to proptosis. Excision of the @entity5 was performed by a lateral rhinotomy approach. The @entity5 proved to be an @entity1179 with focal @entity1606 . Post-operative CT scan revealed @entity41 , which responded to radiotherapy, with no recurrence over six months. Histopathologically, these @entity5 are benign, but locally invasive. The @entity5 that invade the orbit are usually locally aggressive, highly malignant and recur frequently. Radical excision of the @entity5 is technically difficult and often incomplete, so radiotherapy should be considered as an adjunct to surgery.
