"essential: yellow-tan circumscribed mass; uniform proliferation of mature adipose tissue with atypical hyperchromatic stromal cells"
"Intramuscular lipomas have nearly identical histology to superficial lipomas; however, intramuscular lesions tend to invade the adjacent musculature and commonly lack a capsule. These are sometimes known as infiltrating lipomas. In contradistinction, intermuscular lipomas do not exhibit local invasion and tend to be lobular or dumbbell-shaped, easily separated from adjacent soft tissues during surgical resection 6,7."
"Superficial lipomas are typically well-circumscribed ovoid masses with homogeneous imaging characteristics of fat. A thin capsule, very thin septations ("
"Deeper or larger lesions may have scattered areas of internal soft-tissue density, often more apparent on CT versus MRI. These may represent areas of fat necrosis, fibrous tissue, blood vessels, or muscle fibres; these lesions cannot be confidently differentiated from liposarcoma by imaging."
"Lipomas appear as variably echogenic masses on ultrasound. If encapsulated, the capsule may be difficult to identify on ultrasound 5. There is a wide range of appearances of biopsy-proven lipomas, with wide inter-reader variability 8 :"
