Abstract

Schneiderian papilloma is typically found on the lateral nasal wall, but, in rare cases, can be located at the mucosa of the nasal septum. Respiratory epithelial adenomatoid hamartoma (REAH) is rare, non-neoplastic lesion characterized by an abnormal proliferation of glandular part of the respiratory nasal mucosa. We present a case of a 42-year-old man with five-year history of bilateral nasal obstruction, rhinorrhea, epistaxis, and hyposmia. On endoscopic examination, we found lobulated, yellowish-pink soft tissue masses on both sides of the nasal septum. The results of histopathological analyses showed the characteristics of Schneiderian papilloma in the lesion excised from the right and REAH in the lesion excised from the left side of the nasal cavity. To our knowledge, cases of simultaneous presentation of Schneiderian papilloma and REAH on opposite sides of the nasal septum have not been published so far. An appropriate cooperation of rhinologist and pathologist allows for a correct diagnosis of these rare and unusual lesions.
