Congenital sialolipoma of the parotid gland first reported case and review of the literature.
ABSTRACT 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.

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.Clinical and Experimental Otorhinolaryngology 06/2014; 7(2):149-52.

ABSTRACT: Sialolipoma is rare benign neoplasm arise from salivary glands (majors and minors) characterized by neoplastic adipose tissue with scattered non-neoplastic salivary gland acinus. To date 60 cases (including 5 cases reported in the present paper) have been reported in scientific literature. This article presents 5 new cases of sialolipoma affecting minor salivary glands (MiSG) and additionally reviews and analyzes the previously published cases to assess possible demographical differences between sialolipoma from minor and from major salivary glands. Case reports: 5 cases (3 females; 2 males; age means 63.8 years), of sialolipoma from MiSG, are reported. 2 of them were located in buccal mucosa, 1 in upper lip mucosa, 1 in floor of the mouth and 1 in retromolar area. All tumors were composed by neoplastic adipocytes cells interlaced with normal salivary gland acinus cover it by a fibrous tissue capsule. Analyzes of literature showed that MiSG sialolipoma is most frequent in females over 60 years old, therefore and in conclusion this article assess different demographical profile of sialolipoma in respect to their topography.Indian Journal of Otolaryngology and Head & Neck Surgery 03/2015; 67(1).
