Pathology Report for Cancerous Neoplasm

Could you please provide me with information if there is malignancy in this Renal Neoplasm pathology report:

The bulk of the tumor is comprised  of mature adipose tissue with foci of necrosis associated with macorphages and giant cells.   The smooth muscle component is comprised of smooth muscle cells with elongated nuclei.  NUCLEAR PLEOMORPHISM, RARE MITOTIC FIGURES, NUCLEAR ENLARGEMENT AND BIZARRE NUCLEI ARE SCATTERED.  Immature smooth muscle cells with ROUNDED NUCLEI AND CLEAR CYTOPLASM are noted, some of which are arranged in palisades around a certral arteriole.

If malignancy is present, what type of cancer?  I appreciate your time and assistance.

Thank you.
