Dedifferentiated subserosal liposarcoma of the jejunum: sonographic and computed tomographic findings with pathologic correlation.
Dedifferentiated liposarcoma, one of five subtypes of liposarcomas, occurs as a consequence of the progression of well-differentiated liposarcoma to dedifferentiation. Liposarcoma arising from the subserosa of small bowel that can mimic the appearance of mesenteric liposarcoma or teratoma is extremely rare. Here, we report a case of dedifferentiated liposarcoma that developed in the subserosal layer of the jejunum and metastasized to the mesentery.
