A Prostate Peripheral Zone Tumor refers to a growth or cancerous lesion that develops in the peripheral zone (PZ) of the prostate gland. The prostate is a walnut-shaped organ in men, responsible for producing seminal fluid, which is crucial for sperm movement. The prostate has different zones, and the peripheral zone is the largest part, located at the outer region of the gland. Most prostate cancer cases begin in the peripheral zone, making it the area most commonly affected by tumors.
Pathophysiology:
Structure of the Prostate:
The prostate is divided into different zones:
- Peripheral Zone (PZ) – The outermost part, where most prostate cancers begin.
- Central Zone (CZ) – Located at the base of the prostate.
- Transition Zone (TZ) – Surrounds the urethra and is where benign prostatic hyperplasia (BPH) occurs.
- Anterior Fibromuscular Stroma (AFS) – Contains muscle and fibrous tissue, with minimal prostate tissue.
Blood Supply:
The prostate receives its blood supply primarily from the inferior vesical artery, which branches from the internal iliac artery. The blood flow is crucial for supporting prostate function and tumor growth if cancer is present.
Nerve Supply:
The prostate is innervated by the pelvic nerve plexus. Nerves from this plexus regulate prostate function, including semen production, and are important in controlling erectile function.
Types of Prostate Tumors
- Adenocarcinoma: The most common type of prostate cancer, originating in the glandular tissue of the prostate.
- Small Cell Carcinoma: A rare and aggressive type of prostate cancer.
- Sarcoma: A type of cancer that originates in the connective tissue of the prostate.
- Neuroendocrine Tumors: These tumors are less common and may spread quickly.
- Transitional Cell Carcinoma: A rare form of cancer that can affect the prostate and the bladder.
- Prostatic Intraepithelial Neoplasia (PIN): A pre-cancerous condition that can develop into prostate cancer over time.
Causes of Prostate Peripheral Zone Tumor
