Tumours of the parotid gland in children are uncommon, and represent only 1.3% of all benign salivary tumours. Lipomas of the parotid are also rare, and account for 0.5% of all parotid gland tumours. Sialolipoma is a new variant of salivary gland lipoma, consisting of adipose and glandular tissue that was first proposed by Nagao et al. in 2001. Ten cases of parotid gland lipoma associated with glandular elements have been previously reported in the literature. All have been in adults and none in children. We present the first reported case of congenital sialolipoma that had developed in a female infant. It was managed successfully by superficial parotidectomy undertaken at ten weeks of age.
"According to a review of 28 cases of sialolipoma by Jang et al. , the most common site for sialolipoma was the parotid gland (17 cases), followed by the palate (4 cases); sialolipoma arising from the submandibular gland was found in only 2 cases. The age distribution of patients ranged from 7 weeks to 84 years; 1 case reported by Hornigold et al.  was congenital in onset. Previous studies had reported that sialolipoma predominantly affected males [2,5], but this review found the male to female ratio to be 1:1. "
[Show abstract][Hide abstract] ABSTRACT: Sialolipoma, a rare tumor of the salivary gland, is a recently described variant of salivary gland lipoma. Oncocytic sialolipoma was first described by Pusiol et al. in 2009. We report the case of an oncocytic sialolipoma of the submandibular gland in a 43-year-old female. Excision of the tumor was performed with preservation of the submandibular gland. The tumor had a thin, fibrous capsule and consisted of abundant adipose tissue, an oncocytic nodule, and scattered normal glandular structures surrounded by adipose tissue. Four cases of sialolipoma of the submandibular gland, including the present case, were reviewed. All 4 tumors were developed on the right submandibular glands, with a composition of adipose tissue as high as that of sialolipoma of the parotid gland; in contrast to previous reports, three cases were in females. As newly described tumor type, care should be taken to distinguish oncocytic sialolipoma from other salivary gland neoplasms such as simple lipoma, pleomorphic adenoma, or oncocytoma.
"Nineteen cases of sialolipoma were reported in major salivary glands without our cases [Table 2]. Fourteen cases have been reported in the parotid gland and 5 cases in the sub-mandibular gland. "
[Show abstract][Hide abstract] ABSTRACT: Sialolipoma is a rare neoplasm of salivary glands, described as a distinct entity by Nagao et al. in 2001. Thirty-six cases of sialolipoma in minor and major salivary glands have been reported thus far in addition to the two new cases of sialolipoma arising in the major salivary glands in this study. Thirty-six cases of sialolipoma published in English language reports were analyzed considering gender, age, location, size, duration of symptoms, treatment mode, follow-up, and histologic findings. Congenital sialolipomas were considered in this study. The first case occurred in a 45-year-old female and presented as a localized swelling in right parotid area. The second case occurred in an 18-year-old female as a swelling in the left parotid region. On histopathological examination, these lesions were diagnosed as sialolipoma.

[Show abstract][Hide abstract] ABSTRACT: Sialolipoma is a relatively rare and fairly recently described as a variant of lipoma with salivary elements. Any site within the oral and maxillofacial region may be involved with the parotid gland being the most common location. Herein, we present a case of silaolipoma in lower lip. The clinical and histological features and differential diagnosis are discussed.
