Vulval carcinoma metastasizes to which lymph group :
**Core Concept**
Vulval carcinoma is a type of cancer that originates in the vulva, which is the external female genital area. The lymphatic drainage of the vulva plays a crucial role in the spread of this cancer. Understanding the lymphatic pathways is essential for determining the most likely site of metastasis.
**Why the Correct Answer is Right**
The correct answer is related to the lymphatic drainage of the vulva. The vulva drains into the inguinal lymph nodes, which are located in the groin area. This is because the lymphatic vessels of the vulva converge to form larger lymphatic trunks that ultimately drain into the inguinal lymph nodes.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately represent the primary lymphatic drainage site for vulval carcinoma.
**Option B:** This option is also incorrect as it is not the primary site for metastasis of vulval carcinoma.
**Option C:** Similarly, this option does not correctly identify the primary lymph node group involved in the metastasis of vulval carcinoma.
**Option D:** This option is incorrect as well, as the question is about the primary site of lymphatic metastasis.
**Clinical Pearl / High-Yield Fact**
It's crucial to remember that the inguinal lymph nodes are the primary site for lymphatic drainage and metastasis of vulval carcinoma. This knowledge is vital for the clinical management and staging of the disease.
**Correct Answer:** C. Inguinal lymph nodes.
