rasunäärmetsüstid

Rasunäärmetsüstid, also known as sebaceous cysts, are common non-cancerous growths that arise from the sebaceous glands. These glands produce sebum, an oily substance that lubricates the skin and hair. When a sebaceous gland or its duct becomes blocked, sebum can accumulate, leading to the formation of a cyst. The cyst typically appears as a small, firm lump under the skin, often with a small dark spot at its center, which represents the blocked pore.

These cysts can develop anywhere on the body where sebaceous glands are present, but they are most commonly found on the face, neck, and torso. While usually painless, they can become inflamed or infected, causing redness, swelling, and tenderness. In such cases, the cyst may rupture, leading to the discharge of thick, cheesy-smelling material.

The exact cause of blocked sebaceous glands is not always clear, but factors such as damage to the gland, genetic predisposition, or hormonal changes can contribute. They are more common in young adults. Diagnosis is usually made through a physical examination.

Treatment is not always necessary, especially if the cyst is small and asymptomatic. However, if the cyst is causing discomfort, is aesthetically undesirable, or becomes infected, it can be removed. Common treatment methods include drainage, surgical excision, or minimally invasive techniques. It is important not to attempt to squeeze or pop a sebaceous cyst at home, as this can lead to infection and scarring. Medical professionals can safely remove the cyst, often with minimal scarring.
