Endometrial Stromal Sarcoma

Pathophysiology of Endometrial Stromal Sarcoma

Structure

The uterus consists of several layers:

• Endometrium: The inner lining where the embryo implants.
• Myometrium: The muscular middle layer.
• Serosa: The outer layer.

ESS originates in the endometrial stroma, the connective tissue beneath the endometrium. This tissue supports the endometrial glands and blood vessels.

Blood Supply

ESS tumors receive blood through the uterine arteries, which branch from the internal iliac arteries. Adequate blood flow is essential for tumor growth and the spread of cancer cells.

Nerve Supply

The uterus is innervated by the autonomic nervous system, including both sympathetic and parasympathetic fibers. Nerve involvement in ESS can lead to symptoms like pain? or discomfort.

Types of Endometrial Stromal Sarcoma

ESS is categorized based on its behavior and appearance under a microscope:

1. Low-Grade ESS: Grows slowly and is less likely to spread.
2. High-Grade ESS: More aggressive, grows faster, and has a higher chance of spreading.
3. Undifferentiated ESS: Rare and highly aggressive with poor prognosis?.

Causes of Endometrial Stromal Sarcoma

While the exact cause of ESS is unknown, several factors may contribute:

1. Genetic mutations
2. Hormonal imbalances
3. Long-term exposure to estrogen
4. Obesity
