Unexpected XXXX incidence in surgically removed unilateral and bilateral nasal polyps.

@entity5 @entity1 @entity1412 @entity1127
OBJECTIVE: The objective of the study was to investigate the postoperative @entity5 incidence on routine histopathologic examination of surgical specimens in @entity1 who underwent endoscopic sinus surgery with the preoperative diagnosis of unilateral or @entity1412 . METHODS: @entity1 who underwent endoscopic sinus surgery with the preoperative diagnosis of unilateral or @entity1412 between 2000 and 2009 were included in the study as the 2 separate groups. In both groups, @entity5 incidence that had been noticed on routine postoperative histopathologic examination was recorded retrospectively. @entity1 who had a preoperative diagnosis other than @entity1412 , determined on biopsy, were excluded. RESULTS: Of 251 @entity1 included, 197 had the preoperative diagnosis of @entity1412 , and 54 had @entity1412 . No @entity5 was diagnosed on postoperative histopathologic examinations in @entity1 with preoperative @entity1412 . Seven @entity1 (12.96%) with the preoperative diagnosis of @entity1412 had @entity5 on postoperative histopathologic examinations. Two of these 7 @entity1 had @entity5 that were reported preoperatively by intranasal biopsy as @entity1127 . CONCLUSIONS: Diagnosis of a @entity5 is an extremely rare situation, unless there are special findings of @entity5 in @entity1 with preoperative diagnosis of @entity1412 . On the other hand, histopathologic examinations should be carried out in every case operated with preoperative diagnosis of @entity1412 , as the @entity5 incidence is higher.
