• Low power view

• Prostatic urethra central, surrounded by fibrous stroma.

• Ejaculatory ducts lie in the stroma ñ this picture shows them before they have joined the prostatic urethra.

• Partial fibrous septa separate the gland into lobules.

• The TZ surrounds the first part of the prostatic urethra.

• The central zone lies posterior to the TZ and encircles the ED.

• The peripheral zone makes up the bulk of the gland.

• Carcinoma = most often in peripheral zone.

• BPH = most often in transition zone.
