Understanding Dermoid Cysts: Causes and Treatments

Written by Medicover Team and Medically Reviewed by Dr M Kalyan Ravi Teja , General Surgeons

Dermoid cysts are benign, slow-growing growths that develop from embryonic cells and can contain various types of tissue, such as skin, hair, sweat glands, or even teeth. They can occur in different parts of the body, including the ovaries, face, neck, and spine, and are often present from birth, although they may not be noticed until later in life.

What Are Dermoid Cysts?

Dermoid cysts are sac-like growths that may contain a variety of tissue types, including hair follicles, sebaceous (oil) glands, and even teeth or bone. These cysts are classified as germ cell tumours, originating from totipotent germ cells that have the potential to develop into any type of tissue. Most commonly, dermoid cysts are found in the ovaries, but they can also appear in other locations, such as the face, neck, and spine.

Dermoid Cysts and Ovaries

Ovarian dermoid cysts, also referred to as ovarian teratomas, are the most prevalent type. They typically occur during a woman's reproductive years and are usually discovered incidentally during pelvic examinations or imaging studies for unrelated issues. Although generally benign, these cysts can cause complications if not monitored or treated appropriately.

What are the Causes of Dermoid Cysts?

The exact cause of dermoid cysts remains a topic of research and debate within the medical community. However, it is generally believed that these cysts form during embryonic development when germ cells intended to form various tissues become trapped in the wrong part of the body. These misplaced cells then give rise to cysts containing multiple tissue types.

Genetic Factors

While the development of dermoid cysts is not typically linked to hereditary patterns, certain genetic factors might predispose individuals to these growths. Ongoing research aims to elucidate the genetic underpinnings that contribute to the formation of dermoid cysts.

When Should You See a Doctor for Dermoid Cysts?

Consulting a surgeon, gynecologist, or healthcare provider is important if symptoms develop or complications are suspected.

Early evaluation can help prevent complications and determine whether monitoring or treatment is needed.

What are the Symptoms of Dermoid Cysts?

Dermoid cysts often remain asymptomatic, especially when small. However, larger cysts can exert pressure on surrounding tissues and organs, leading to a range of symptoms:

How is the Diagnosis of Dermoid Cysts?

Accurate diagnosis is crucial for determining the appropriate treatment strategy for dermoid cysts. The following methods are commonly employed in the diagnostic process:

Imaging Techniques

Histopathological Examination

In some cases, a biopsy may be performed to obtain a tissue sample from the cyst, which is then examined under a microscope. This examination helps differentiate dermoid cysts from other types of cysts or tumours.

What is Treatment Options for Dermoid Cysts?

The treatment for dermoid cysts depends on several factors, including the cyst's size, location, and symptoms. Here are some standard treatment options:

Watchful Waiting

For small, asymptomatic dermoid cysts, especially those in non-critical areas, a conservative approach of regular monitoring may be recommended. This involves periodic imaging studies to ensure the cyst does not grow or cause complications.

Surgical Removal

Potential Complications

While dermoid cysts are generally benign, complications can arise, particularly if the cyst becomes large or ruptures. Potential complications include:
