Rare benign fatty neoplasm
Meis and Enzinger (1993)
Slow growing painless subcutaneous or deep soft-tissue mass
Female predilection
from 14 to 70 years
Proximal extremities and limb girdles are commonly involved, trunk, head and neck may also be involved.
Encapsulated, often multilobular
Well-defined mass with fluidlike areas on US, CT and MR due to large myxoid consistency of the tumor. These lesions often contain only a small amount of fatty tissue, either peripherally or centrally as subtle strands, a finding best seen at MR imaging. Calcification is usually present
Surgically resected. No recurrence or malignant change
