ABSTRACT
Lipoma is an uncommon benign, oral, soft-tissue neoplasm commonly found on the buccal mucosa. It is predominantly composed of mature fat with or without other mesenchymal tissue elements, showing a variety of histologic subtypes, one of which is the rare "spindle cell variant" with only nine previously reported cases in the English literature. In this report, we review clinical and histomorphologic data of 164 cases of oral lipomas retrieved from the files of Long Island Jewish Medical Center, Department of Dental Medicine (New Hyde Park, NY). Of these, only two cases were diagnosed as the spindle cell variant, further confirming the rarity of this histologic subtype. A review of oral lipoma with particular reference to the spindle cell variant is also presented.
