infiltrating lipoma

(1)  An extremely rare variant of lipoma that infiltrates adjacent tissues and tends to recur after excision.
(2) An (incorrect) synonym for liposarcoma.


a benign fatty tumor usually composed of mature fat cells. They have a special importance in horses, in which the pedunculated tumors in the abdominal cavity uncommonly twist themselves around a loop of small intestine, sometimes just below the pylorus or around the rectum. The occurrence of this particular form of colic is limited to horses 12 years or older. The clinical signs are not diagnostic except that the strangulation of the rectum causes a purse-string closure of the lumen just inside the anus and is easily detected at rectal examination.
