It is comprised of both epithelial (carcinomatous) and stromal (sarcomatous) components.

Implicated risk factors include 1:

  • advanced age
  • excess estrogen exposure
  • nulliparity
  • prior pelvic irradiation: estimated in 10-30% of cases
  • tamoxifen

Imaging features are somewhat dependent on location and are best discussed under respective sections. In general, they tend to be large bulky lesions.

They are aggressive neoplasms and lung, liver and bone are common sites of metastases.
