Dermoid cyst

A Dermoid cyst, also known as a teratoma, is a benign tumor that typically originates from germ cells, the cells responsible for developing into all the different types of tissues in the human body. These cysts are encapsulated, meaning they are enclosed in a membrane, and can contain a variety of tissue types, including skin, hair, teeth, and fat.

Formation

Dermoid cysts are usually present at birth and grow slowly. They can occur anywhere in the body, but are most commonly found in the ovaries, testes, and at midline structures of the body, such as the head, neck, and spinal cord. The exact cause of dermoid cysts is unknown, but it's believed they form from embryonic cells, the cells present when a baby is developing in the womb.

Symptoms

The symptoms of a dermoid cyst depend on its location. If it is in the skin, it may be a noticeable lump. If it is in the ovaries, it can cause abdominal pain, bloating, or changes in menstrual cycle. When it is present in the brain or spinal cord, it may cause seizures, headache, or other neurological symptoms.

Diagnosis and Treatment

• Dermoid cysts are usually diagnosed through imaging studies, such as ultrasound, CT scan, or MRI. A biopsy, where a sample of the cyst is removed for examination under a microscope, may also be performed.
• The primary treatment for a dermoid cyst is surgical removal. If the cyst is left untreated, it can grow, causing discomfort or complications, and in rare cases, can become malignant.
