초록
Sialolipoma is a new variant of salivary gland lipoma containing secondary entrapment of acini and ducts of normal salivary gland, first described by Nagao et al. in 2001. We present the clinicopathologic features of two cases, with a review of 18 cases of sialolipoma reported in the literature so far. In our cases, both 59-year-old and 74-year-old men had painless, movable, and soft mass. The finding of neck enhanced computed tomography was a well-demarcated hypodense mass within the superficial lobe of left parotid gland in both cases. So we performed a superficial parotidectomy with preservation of the facial nerve. Grossly, this tumor was a well-demarcating, soft, greasy, yellowish mass, and microscopically, it consisted of mature adipose tissues and normal entrapped glandular epithelium of acini and ducts. This had been recently recognized as a separate entity under the term, “sialolipoma”. We report two cases with a review of the literature. (Korean J Otorhinolaryngol-Head Neck Surg 2008;51:371-5)
