[Inflammatory pseudotumor of paranasal sinuses]

Inflammatory pseudotumor is a rare benign lesion of unknown etiology which was first described in the lung. In head and neck the areas most commonly involved are the orbit and paranasal sinuses, but they have been also described in the larynx, pterygomaxilar space, tonsils, ears, gingiva and other periodontal tissues. We present a case of a 64 years old male who presented a three months history of right nasal obstruction. Physical examination showed a big nasal tumor arising from the nostril. CT scan shows nasal fossa mass with a normal paranasal sinuses. Histology made the diagnosis of an inflammatory pseudotumor. The lesion was surgically removed trough a midface degloving approach. The patient has no signs of recurrence two years after surgery. Data about diagnosis, treatment and outcome of inflammatory pseudotumors is revised also in this paper.
