Sialolipoma of salivary glands: Two case reports and review of the literature

Abstract

The sialolipoma is a rare neoplasm of salivary glands, described as a distinct entity by Nagao et al. in 2001. Thirty-six cases of sialolipoma in minor and major salivary glands have reported thus far in addition to reporting two new cases of osteolipoma arising in the major salivary gland in this study. Thirty-six cases of sialolipoma that published in English language reports were analyzed including gender, age, location, size, duration of symptoms, treatment mode, follow-up, and histologic fi nding. Congenital sialolipomas were considered in this study. Also, two new cases of this lesion are reported in this study. The fi rst case occurred in a 45-year-old female and presented as a localized swelling in right tragus. The second case occurred in an 18-year-old female as a swelling in the left parotid region. On histopathological examination, these lesions were diagnosed as sialolipoma.
