Sialolipoma of the parotid gland with diffuse sebaceous differentiation in a female child.

Sialolipoma of the salivary gland is a tumor with ambiguous histogenesis. Histologically, this lesion is composed of mature adipose tissue and salivary glandular components. To the best of our knowledge, only 12 documented cases of sialolipoma have been reported in the literature. Except for 1 congenital case, all of the cases were found in adult patients. In this report, we present a unique case of sialolipoma with diffuse sebaceous differentiation in a 3-year-old female child. The differential diagnoses are discussed.
