Among the differential diagnosis are lipoma, lipoblastoma, fibromatosis, cystic hygroma and pilomatrixoma.
Those in which adipose tissue predominates are distinguished from fibrolipoma by foci of immature mesenchyme and from lipoblastoma by their lack of a capsule and of a lobular pattern .
Lipoblastoma is a rare tumor composed of fetalembryonal fat that occurs exclusively in infants and children.
Plain radiography in patients with lipoblastoma generally shows a nonspecific soft tissue mass.
are benign mesenchymal tumours of embryonal white fat.
This histopathologic picture was consistent with the diagnosis of lipoblastoma.
First described by Jaffe, (2) a lipoblastoma is a developmental anomaly characterized by continued proliferation of lipoblasts in the postnatal period.
In conclusion, giant liposarcomas in scapular region are extremely rare; and possible differential diagnosis may be lipoma, lipoblastoma
, pleomorphic lipoma, chondroid lipoma, hibernoma and neurofibroma etc.
is a rare benign tumor that occurs primarily in children younger than 3 years of age.
Lipomas, lipomatosis, angiolipomas, chondroid lipomas, lipoblastoma
, lipobalostomatosis, spindle cell lipoma and pleomorphic lipomas are lesions that can mimic the condition.
The differential diagnosis of a mammary hibernoma includes nonneoplastic inflammatory or reactive processes such as fat necrosis and xanthogranulomatous mastitis, other soft tissue tumors with lipomatous differentiation such as lipoblastomas
, and some benign and malignant breast neoplasms such as granular cell tumor and histiocytoid carcinomas.
 According to Fugemann, the benign lipomatous tumors of this region can be further subclassified as solitary or multiple classic lipomas; infiltrating or intramuscular lipomas; hibernomas; lipoblastomas
(socalled fetal lipomas); and diffuse lipomas in children.
