Previously reported liposarcoma cases in infancy are mostly deemed as lipoblastomatosis
It has been suggested that fibrolipoma arise from the maturation of the lipoblastomatosis
which is an infiltrative type of benign neoplasm with lobules of immature fat cells separated by connective tissue septa and areas of loose myxoid matrix.
5) Histologically the well-circumscribed and encapsulated features of lipoblastoma differentiate it from the multicentric and infiltrative nature of lipoblastomatosis
1) In 1973, Chung and Enzinger suggested the terms benign lipoblastoma to describe the circumscribed type of tumor and benign lipoblastomatosis
to describe the condition in which multiple tumors are locally diffused.
This variety of lipoblastoma has been termed lipoblastomatosis.
Both lipoblastoma and lipoblastomatosis have a benign course, though they both have a tendency to recur in spite of complete excision.
Lipoblastomatosis is a rare, fat-containing, benign tumor that should be considered as a differential diagnosis of recurrent soft tissue neck masses in infants and children.
