Oral fibrolipoma: A rare clinicopathological entity

Abstract

Fibrolipoma, a subtype of lipoma, is a painless, well-circumscribed, slow-growing, submucosal benign adipocyte tumour. It is uncommon in the oral cavity and oropharyngeal region. It accounts for 1.6% of all facial lipomas. Fibrolipomas mostly affect the buccal mucosa and buccal vestibule and cause functional and cosmetic disabilities. The diagnosis and differentiation of fibrolipoma with clinically similar lesions such as fibroma and pleomorphic adenoma are very essential for a correct treatment plan and complete follow-up. Here, we present fibrolipoma, a very rare subtype of lipoma involving the buccal mucosa of the left premolar region in a 44-year-old male patient.
