Definition / general
- 2% of all leiomyomas; combination of leiomyoma and mature adipocytes with benign behavior (Int J Gynecol Pathol 2006;25:239)
- Also includes neoplasms composed entirely of mature adipocytes
- May be due to adipose metaplasia in leiomyomas; does not appear to be degenerative, since adipose tissue has low proliferative activity by Ki67 staining
- May give rise to liposarcoma (Am J Surg Pathol 2011;35:221)
