DEEP-SEATED LIPOMAS

Abstract

Lipoma is encountered by every clinician so frequently in one site, the subcutaneous tissues, that the possibility of its occurrence in other areas is easily forgotten. For that reason a brief report is here made of four cases of simple lipoma situated in and beneath the muscles. Intramuscular lipoma is exceedingly rare.
