Chondrolipoma of floor of the mouth: A case report

Chondrolipoma is one of the less common variants of lipoma, showing mature hyaline cartilage in the underlying adipose tissue. We describe herein a rare case of chondrolipoma arising on the floor of the mouth. A 66-year-old woman was referred for close examination of a lingual mass on the anterior floor of the mouth. Intraoral examination revealed a spherical, well-defined, relatively soft mass, 2.0 cm in diameter, without adhesions to alveolar bone in the anterior floor of the mouth. The tumor was resected, and histopathologic examination diagnosed chondrolipoma. The postoperative course was uneventful and no recurrence within 1 year after surgery. Lipomas are also occasionally found on the floor of the mouth, where the chondrolipoma subtype can arise.
