“…Very few cases of submandibular gland sialolipoma are reported. To the best of our knowledge, only 3 cases of submandibular gland sialolipoma have been reported in the English literature, all in adults [5][6][7]. We present the first reported case of submandibular gland sialolipoma in a child.…”

“…Sialolipoma is characteristically composed predominantly of adipose tissue with admixed islands of salivary gland acini, ductal, myoepithelial and basal cells [32]. The epithelial/myoepithelial elements may show focal oncocytic change in some cases [32][33][34][35], but unlike oncocytic lipoadenoma, sialolipoma in general lacks a prominent oncocytic component. The tumor tends to show lobulation with evenly distributed salivary gland elements within the fat.…”

Oncocytic lipoadenoma is an exceedingly uncommon neoplasm of the salivary gland composed of oncocytic epithelium and adipose tissue. Retrospective. Seven cases of oncocytic lipoadenoma were analyzed in order to further characterize the clinical and pathologic features of this rare tumor. The patients included six males and one female who ranged from 40 to 83 years of age (mean 62 years) at presentation. All tumors arose in the parotid gland. Grossly, the tumors were solitary, well circumscribed and had light brown to yellow cut surfaces. Histologically, the tumors were composed of an admixed population of oncocytes and adipocytes in varying proportions, with the lipomatous component ranging from 5 to 70 %. Other common features included the presence of serous acini, ductal elements, sebaceous glands, and a patchy chronic inflammation. Clinical follow up information, available in all cases, with a duration of 3-148 months (mean 57 months), showed no evidence of tumor recurrence. Due to its rarity, oncocytic lipoadenoma can pose problems in diagnosis, although the distinctive morphologic features of this neoplasm allow for separation from more commonly recognized oncocytic neoplasms of the salivary glands.

“…Adipose tissue composes a higher percentage of parotid gland sialolipomas (90% or more) than sialolipoma arising in other sites (50%-80%) [2,5,6]. Four cases of sialolipomas arising in the submandibualr gland were analyzed and found to have a proportion of adipose tissue as high as that of the parotid gland sialolipomas [3,4,7] (Table 1). Hence, a more accurate statement might be that major salivary gland sialolipomas have a higher proportion of adipose tissue than do those of the minor salivary glands.…”

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.
