title: Fine needle aspiration of inverted Schneiderian papilloma. A case report.
abstract: The cytologic and histopathologic findings in an inverted Schneiderian papilloma of the paranasal sinuses are described. This uncommon neoplasm of the sinonasal region is characterized by a significant recurrence rate and an association with squamous cell carcinoma in 7-13% of patients. Fine needle aspiration of inverting papillomas may allow rapid identification of the lesion when a tissue biopsy is impractical.
