Lymphatic Spread carcinoma Prostate

MCQ on Most Common Lymph Node Involved in Prostate Carcinoma
Q) Most common lymph node involved in carcinoma prostate is
Answer: A. Obturator

🔍 Explanation:
The most common lymph node involved in **prostate carcinoma** is the **obturator lymph node**.

Lymphatic spread may occur via lymphatic vessels that pass to the **obturator fossa**, along the sides of the rectum to the lymph nodes near the **internal iliac vein** and in the hollow of the sacrum.

Additionally, lymphatics pass over the **seminal vesicles** and follow the **vas deferens** for a short distance to drain into the **external iliac lymph nodes**.

From the retroperitoneal lymph nodes, the **mediastinal nodes** and occasionally the **supraclavicular nodes** may become implicated.

🧠 Key Point: **Obturator lymph nodes** are the first to be affected in prostate cancer due to the nature of lymphatic drainage from the prostate.
