Prostatic stromal tumour of uncertain malignant potential, usually abbreviated STUMP,[1] is a rare lesion of the prostatic stroma which cannot be definitively classified as benign or malignant.
It is also known as prostatic stromal proliferation of uncertain malignant potential (abbreviated PSPUMP').[2]
