Abstract
The clinical and pathological-anatomical features of lipomas of the hypopharynx, based on a review of 23 cases presented in the literature and exemplified by a new case, are discussed. The tumor may be solitary or multiple and appears mostly in men over the age of 40. Although it may reach a considerable size, it may be asymptomatic until it appears in the mouth or suffocation occurs. Recurrences are rare but metachronous multiple lipomas may appear. Long term follow-up is therefore recommended. The difficulties of differential diagnosis between lipomas and well-differentiated liposarcomas are discussed.
