Granulosa Cell Tumor

Granulosa cell tumors are rare ovarian cancers that arise from granulosa cells, which are responsible for producing estrogen and supporting the development of eggs in the ovaries. This guide provides an in-depth look at granulosa cell tumors, covering their definition, pathophysiology, types, causes, symptoms, diagnostic tests, treatments, prevention, when to seek medical attention, and frequently asked questions.

A granulosa cell tumor is a type of ovarian cancer that originates from granulosa cells. These cells play a crucial role in the reproductive system by producing estrogen and nurturing the eggs within the ovaries. Granulosa cell tumors are part of a broader category called sex cord-stromal tumors and are considered rare, accounting for approximately 2-5% of all ovarian cancers.

Key Points:

• Origin: Arises from granulosa cells in the ovaries.
• Function of Granulosa Cells: Produce estrogen and support egg development.
• Rarity: Makes up a small percentage of ovarian cancers.

Pathophysiology

Understanding the pathophysiology of granulosa cell tumors helps in comprehending how these tumors develop and affect the body.

Structure

Granulosa cell tumors are composed of granulosa cells that form structures resembling the ovarian follicles. These tumors can be classified based on their appearance:

• Adult Granulosa Cell Tumors: More common in adult women and have a slow growth rate.
• Juvenile Granulosa Cell Tumors: Occur in younger females and tend to grow more rapidly.

Blood Supply

These tumors develop their own blood supply through a process called angiogenesis, which allows them to receive nutrients and oxygen to support their growth.

Nerve Supply

Granulosa cell tumors can invade nearby nerves, leading to pain and other neurological symptoms. The extent of nerve involvement can influence the severity of symptoms and the complexity of treatment.

Types of Granulosa Cell Tumors

Granulosa cell tumors are primarily categorized into two types:

1. Adult Granulosa Cell Tumor (AGCT)
   • More prevalent in adult women.
   • Generally slow-growing.
   • Often diagnosed at a later stage due to subtle symptoms.
2. Juvenile Granulosa Cell Tumor (JGCT)
   • Occurs in younger females, including children.
   • Tends to grow faster than AGCT.
   • May present with more pronounced symptoms early on.
