Sialolipoma of Minor Salivary Gland in Uvula

Basak K, Kayipmaz S and Karadayi N

Lipomatous lesions of the salivary glands are rare, accounting for less than 0.5% of all parotid gland tumours. Distinct microscopic variants of lipoma of the salivary glands, e.g. angiolipoma, fibrolipoma, pleomorphic lipoma and spindle-cell lipoma have been reported. A 45 year-old male patient with mass on uvula was presented. The specimen was capsulated, yellow coloured, soft tissue with 1.3 cm in greatest diameter. Whole-mount section showed tumor composed by mature adipocytes, salivary gland parenchymal tissue and lymphoid follicles surrounded by a fibrous capsule. Salivary gland component consist acinar and ductal elements. In some areas, glandular components were atrophic. Lymphoid follicles and focal fibrosis were seen. Oncocytic, sebaceous, and squamous metaplasia were not observed. Sialolipomas were composed predominantly of adipose tissue and showed expansive growth with fibrous capsule. Sialolipomas were reported at parotid gland, submandibular gland, hard and soft palate. To our knowledge, such a case in uvula localization was not previously presented.
