NCIt definition : A benign, well-defined, lobulated, myxoid or gelatinous tumor that arises from the
vulva. It shares morphological features with lipoblastoma, myxoid liposarcoma, and
spindle cell lipoma. It is characterized by a lobulated growth and is composed of
mature adipocytes, lipoblasts, and spindle cells without atypia in a myxoid matrix.
DDIT3 and PLAG1 gene rearrangements seen in lipoblastoma and myxoid liposarcoma are
not present in this tumor. It can recur infrequently and there are no reports of metastasis.;
