Intraoral spindle cell lipoma: case report with correlated light and electron microscopy.
A nontender submucosal nodule in the anterior floor of the mouth of a 33-year-old woman was removed surgically. Light and electron microscopic studies revealed features of a spindle cell lipoma, i.e., a well-circumscribed, unencapsulated mass composed of a mixture of univacuolated lipocytes and fibroblast-like spindle cells within a mucinous and collagenous stroma. To our knowledge this is the first reported case of a spindle cell lipoma in the oral cavity.
