- Atypical spindle cells.
- Necrosis or increased mitotic activity.[1]
DDx:
- Prostatic stromal tumour of uncertain malignant potential (STUMP).
- Gastrointestinal stromal tumour.[2]
- Other sarcomas.
- Carcinosarcoma of the prostate.[3]
- Radiation changes.
- Sarcomatoid prostate carcinoma - classically has conventional prostate carcinoma, frequently postradiation treatment.
