A Sialoangiolipoma of Submandibular Gland Origin Case Report

Salivary gland mesenchymal (non-epithelial) tumors are rare tumors and they constitute approximately 2%-5% of all salivary gland tumors. They are most commonly observed in the parotid gland, approximately 90%. Sialolipoma describes well-demarcated tumoral formations that are histologically similar to normal salivary gland tissue containing mature fat cells and different ductal, basal, acinar, and myoepithelial cells. The hamartomatous variant of sialolipoma is defined as sialoangiolipoma and is seen very rarely. Four cases have been described in the literature so far, and only one of them is of submandibular gland origin. In this study, we aimed to present a rare case of sialoangiolipoma of submandibular gland origin.
