The designation 'sialolipoma’ is given to a recently described histologic variant of lipoma characterized by well-demarcated proliferation of mature adipocytes with secondary entrapment of salivary gland elements. Nagao et al from Japan first described this new variant. These tumors have been observed in both the major and minor salivary glands with around 35 cases being reported in the English literature. The most common site for the tumor is the parotid (17 cases, 60.7%) followed by the hard palate (four cases, 14.2%). We report a similar case of sialolipoma arising in the hard palate presenting in a 45-year-old male. Diagnosed as an ordinary lipoma of the hard palate, complete surgical removal of the tumor was done. The histopathological features showed a well-encapsulated lesion exhibiting both adipose tissue and glandular epithelium, and based on the recent criteria of histological findings of sialolipoma, the tumor was diagnosed as sialolipoma of the hard palate. Because of its rarity, it was fitting to report this entity.
