title: Pleomorphic adenoma in the nasal cavity: a clinicopathological study of ten cases in Finland.
abstract: The objective of the study was to investigate the nationwide occurrence of sinonasal pleomorphic adenoma in Finland. A retrospective study was conducted at The Departments of Otorhinolaryngology-Head and Neck Surgery, and Pathology at the five university hospitals in Finland. Data were obtained by searching for sinonasal pleomorphic adenoma cases in the clinical and histopathological registries at these institutions for the past two to four decades. All patients who had had a histologically proven pleomorphic adenoma in the sinonasal area were included as participants. Ten cases with pleomorphic adenoma of the nasal cavity were found. The majority of these tumours originated in the septum, and there were no malignant transformations. Pleomorphic adenomas of the nasal cavity were found to be extremely rare in this nationwide investigation.
