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: Oncocytic lipoadenoma is a rare salivary gland tumour composed of adipose tissue and oncocytic epithelial cells in varied proportions. This tumour is still not included in the current WHO classification of salivary gland neoplasms. We herein report a further case of oncocytic lipoadenoma originating in the parotid gland of a 55-year-old woman. The tumour presented as a slowly growing asymptomatic left-sided parotid gland mass. The resected tumour measured 2.7 cm in maximum diameter and was composed of oncocytoma-like epithelial component admixed with mature adipocytes that made up 10% of the whole mass. Foci of sebaceous differentiation were seen. This rare variant of lipomatous salivary gland tumours is in need of more recognition and should be distinguished from other fat-containing salivary gland lesions, particularly lipomatous pleomorphic adenoma and myoepithelioma.International journal of clinical and experimental pathology 01/2012; 5(9):1000-6. · 1.78 Impact Factor

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.The Open Dentistry Journal 01/2012; 6:208-11. DOI:10.2174/1874210601206010208

ABSTRACT: Sialolipoma is a recently described histologic variant of lipoma and is characterized by well-demarcated proliferation of mature adipocytes with secondary entrapment of salivary gland elements. These tumors have been observed in both the major and minor salivary glands, with more than 20 cases being reported in the English literature. In general, the clinical presentation of sialolipomas of the minor salivary glands suggests a diagnostic hypothesis of salivary gland lesions, commonly neoplasms. In the major salivary glands, the clinical features suggest either a salivary gland neoplasm or a lipoma. Surgical excision is the treatment of choice for sialolipomas, with no reports of recurrence or malignant transformation. The present article reports 4 additional cases of sialolipoma, all of them affecting the minor salivary glands, and reviews the literature regarding clinicopathologic aspects, differential diagnosis, and therapeutic management of this recently recognized histologic variant of lipoma.Annals of diagnostic pathology 03/2010; 15(1):6-11.
