Sialolipoma: report of two cases and review of the literature. 
Sialolipoma is a new variant of salivary gland lipoma first described in 2001.  We present 2 cases of sialolipoma involving the soft palate and buccal mucosa of 2 female patients.  A review of the English language literature revealed 16 cases of sialolipoma reported thus far.  We have reviewed the clinicopathologic features of the literature cases and are adding the present 2 cases for a total of 18 cases.  To the best of our knowledge, this is the first report of sialolipoma involving the buccal mucosa and the second case in the soft palate.  The purpose of this publication is to increase awareness of this recently described variant of lipoma and to address the diagnostic challenges posed both clinically and histopathologically.
