Multiple infiltrating lipomas of the tongue.

A rare case of multiple infiltrating lipomas in the tongue of a 54-year-old man is reported. There have been only five previously reported cases of infiltrating lipoma of the tongue. They were all solitary in nature. The present lesion is the first case reported in the English literature of multiple infiltrating lipoma of the tongue. Because of its infiltrating nature, this tumour may be mistaken for a liposarcoma. Achievement of adequate surgical margins is essential, as the recurrence rate may be as high as 62.5 per cent without complete excision.
