Liposarcoma
Published in Dongyou Liu, Tumors and Cancers, 2017
Classified along with fibroblastic or myofibroblastic tumors, so-called fibrohistiocytic tumors, smooth muscle tumors, pericytic or perivascular tumors, skeletal muscle tumors, vascular tumors, chondro-osseous tumors, gastrointestinal stromal tumors, nerve sheath tumors, tumors of uncertain differentiation, and undifferentiated or unclassified sarcomas under tumors of soft tissues [1], adipocytic tumors are divided into (1) benign (lipoma, lipomatosis, lipomatosis of nerve, lipoblastoma or lipoblastomatosis, angiolipoma, myolipoma, chondroid lipoma, extrarenal angiomyolipoma, extra-adrenal myelolipoma, spindle cell or pleomorphic lipoma, and hibernoma), (2) intermediate (locally aggressive) (atypical lipomatous tumor [ATL] or well-differentiated liposarcoma [LPS]), and (3) malignant (dedifferentiated LPS, myxoid LPS, pleomorphic LPS, and LPS not otherwise specified [NOS]) [1].

Lipomas are common benign soft tissue tumors composed of mature white adipocytes. Lipoma, along with angiolipoma, spindle cell lipoma, pleomorphic lipoma, hibernoma, chondroid lipoma and lipoblastoma are categorized as benign lipomatous tumors [1]. Based on the depth of lesion, lipomas can be classified into superficial and deep lipomas. Superficial lipomas are typically asymptomatic and frequently found in the upper back, neck, shoulder and abdomen. Approximately 5–8% of lipomas present as lipomatosis, which lesions are microscopically indistinguishable from solitary lesion.

Orbital lymphoma is typically a salmon colored mass, hard on palpation, and adherent to the surrounding planes. Its progression is also more rapid than that of SOFP. Pleomorphic lipoma and liposarcoma, especially well-differentiated forms, are also usually clinically distinguishable from SOFP.
