Infiltrating Lipomata of The Head and Neck

Recent discovery and subsequent excision of two histologically benign but unusual infiltrating intramuscular lipomas prompted a review of available literature and a collection of lipomatous disorders of interest to the head and neck surgeon. Such lesions may, by their position, cause significant symptoms. Other instances occur wherein their unusual location causes initial confusion in diagnosis. Finally, accurate histologic identification may be obscured by the inclusion of other tissues within the benign fatty tissue.
