Oral Fibrolipoma Arising from Maxillary Alveolus: A Rare Case Entity

Abstract

Lipoma is a non malignant tumour of adipocytes. Lipomas are most commonly seen during 4th to 6th decades of life. About 20% lipomas are seen in head and neck region of which only 1-4% have been reported in oral cavity. Most common site of occurrence in oral cavity is buccal mucosa and tongue (50%). Various histological variants of lipoma have been identified, which include fibrolipoma, angiolipoma, infiltrating (intramuscular) lipoma, pleomorphic lipoma, osteolipoma, sialolipoma, chondrolipoma, myxolipoma and spindle cell lipoma. Fibrolipoma is a rare histological variant and occurrence on alveolus is even rare. This case reports a case of fibrolipoma of size 2×2 cm arising from maxillary alveolus in a 42-year-old female patient with a long standing history of four years.
