Sertoli-Leydig cell tumours (SLCTs) are rare ovarian tumors that develop from sex cord-stromal cells. They are most commonly found in women of reproductive age and can produce hormones like androgens, leading to various symptoms. This guide provides a detailed overview of SLCTs, including their definitions, pathophysiology, types, causes, symptoms, diagnostic tests, treatments, prevention strategies, and frequently asked questions.

A Sertoli-Leydig cell tumour is a rare type of ovarian cancer that originates from sex cord-stromal cells. These cells are responsible for producing hormones like testosterone. SLCTs are often found in women between the ages of 15 and 35 but can occur at any age. They can produce excess androgens, leading to symptoms such as irregular menstrual periods, excessive hair growth, and other masculinizing effects.

Pathophysiology

Structure

SLCTs arise from Sertoli and Leydig cells, which are part of the ovarian stroma. Sertoli cells support and nourish developing sperm cells in males, while Leydig cells produce testosterone. In females, these cells contribute to hormone production and follicle development.

Blood Supply

SLCTs receive blood supply through the ovarian arteries. Adequate blood flow is essential for tumor growth and survival.

Nerve Supply

Like other ovarian tumors, SLCTs have nerve endings that can cause pain and discomfort as the tumor grows.

Types of Sertoli-Leydig Cell Tumours

SLCTs are categorized based on their degree of differentiation:

1. Well-Differentiated: These tumors resemble normal Sertoli and Leydig cells and tend to grow slowly.
2. Moderately Differentiated: They show some abnormalities in cell structure and growth patterns.
3. Poorly Differentiated: These are more aggressive, with cells that look very different from normal cells and tend to spread quickly.

Causes of Sertoli-Leydig Cell Tumours

While the exact cause of SLCTs is unknown, several factors may contribute to their development:

1. Genetic mutations
2. Family history of ovarian cancer
3. Hormonal imbalances
4. Environmental factors
5. Exposure to certain chemicals
6. Previous history of ovarian tumors
7. Age-related changes
8. Lifestyle factors
9. Immune system disorders
