Lipomas are common soft tissue neoplasms; however, they are found rarely in the parotid gland region. The purpose of this study was to analyze the diagnostic challenges of this rare condition. We performed a retrospective analysis of 11 patients with parotid lipomas, treated from November 2009 to February 2014. The mean age at diagnosis was 46.6 +/- 2.9 years, and the study population included 8 males and 3 females. Computed tomography (CT) and/or magnetic resonance imaging (MRI) were performed in radiological diagnosis. Fine needle aspiration (FNA) was performed in all cases (including two times in five patients, for a total of 16 biopsies) and results were diagnostic in four instances. Specificities of the CT, MRI, and FNA cytology tests were 100%, 100%, and 25% respectively. CT and/or MRI scans were more reliable than FNA cytologies for accurate diagnosis of parotid lipomas.
