Sialolipoma is a new variant of salivary gland lipoma, which was first proposed by Nagao et al. ( Histopathology 2001; 38: 30) in 2001. We report this rare case of sialolipoma in the hard palate. A 60‐year‐old Japanese woman was referred to our department complaining of a painless swelling on the right side of the hard palate. Intra‐oral examination revealed a soft, elastic, dome‐shaped mass with 1 cm in diameter located in the posterior part of the hard palate. Magnetic resonance imaging examination revealed high intensity on T 1 ‐weighted image and isointensity on T 2 ‐weighted image. Incisional biopsy revealed that the tumor was encapsulated by fibrous tissue, consisted of adipose tissue, and also contained normal salivary gland tissue peripherally. First diagnosed as an ordinary lipoma of the hard palate, the tumor was excised. According to the recent criteria of histologic findings of sialolipoma, we rediagnosed the tumor as sialolipoma of the hard palate.
