Sialolipoma: case report and review of 27 cases.

INTRODUCTION: This article presents a patient with sialolipoma of the submandibular gland, a rare neoplasm, and reviews related literatures. A MEDLINE literature and articles published in the Korean language in KMbase (kmbase.medric.or.kr) search was performed and the literatures were reviewed. DISCUSSION: We presented a sialolipoma of the submandibular gland and other 27 cases from published literatures. Our case was shown in 62-year-old female. It was the second case of submandibular gland sialolipoma reported in the English literature. Unlike other lipomatous lesion in the oral cavity, definite male predilection was not observed in the sialolipoma. The most common site for the tumor was the parotid gland (17 cases, 60.7%), followed by the palate (four cases, 14.2%). Histopathologically, a tumor was a benign lesion with proliferating lipocytes including scattered foci with a normal salivary gland tissue. Our treatment of choice was surgical excision and recurrent case has not been reported.
CONCLUSION: Sialolipoma is a rare benign neoplasm in the head and neck and it shows equal sex predilection.
