As you can see, the tissue of the prostate is still well-differentiated (ie organised into glands and stroma) but there is a nodule in the bottom left quarter of the slide that seems to contain several gland-like structures. This is characteristic of nodular prostatic hyperplasia, where nodules of excessive growth are interspersed with normal tissue. It's not a precursor of carcinoma, but it might cause outflow obstruction of the bladder.
