A high index of suspicion is required for the diagnosis of such a forgotten entity.

These data show that AR is common in the Middle East region as elsewhere in the world. Many patients with AR in Middle East region suffer from their symptoms (e.g., runny nose, nasal itching, nasal congestion, postnasal drip, and other symptoms) on all or most days during the times of the year that their allergies are worst. These symptoms have been shown to reduce QOL and performance at work/school to a significant degree. Additionally, the survey data underscore a considerable treatment gap with current therapies for AR and that many AR patients still have not found adequate effectiveness with currently available medications. Thus, through identification of disease impact on the Middle East population and highlighting treatment gaps, clinicians in the Middle East may better understand and treat AR, leading to improvements in overall patient satisfaction and QOL.

Sinonasal renal cell-like adenocarcinoma is a rare and distinct entity noteworthy in its resemblance to RCC. Immunohistochemistry can easily distinguish between these two tumors. No patient developed recurrent or metastatic disease, or was found to have RCC. Greater experience will allow us to fully understand its long-term behavior and arrive at more standardized therapeutic recommendations.

We report a rare case of an ectop ic third molar at the level ofthe osteo niea tal comp lex. A 2 1-year-old man came to us with a left-sided nasal obs truction of 2 years' duration. Comp uted tom ograph y ofthe pa ran asal sinuses reve aled that an aberrant tooth was obstructing the osteotnea tal comp lex and bulging into the ethmo id infundibulum. Opa city of the entire left maxillar y sinus indicated the presence ofan asso ciated cys tic fo rmation. A tran snasal endosco pi c sinus technique was emp loye d to create a large middle meatal antros tomy and to remove the tooth as well as the cystic contents and cys t wall. Path ologic analys is reveal ed that the cys t was denti gerous. Af ter recoveryfront surgery , the pati ent resumed nasal breathing. The endoscopic surg ica l approach used in this case caused less morbidity tha n do the more commo n methods (e.g., the Caldw ell-Luc p rocedure) of remov ing ectop ic teeth fro m the sinus.
