The primary cause of sebaceous cysts lies in the blockage or damage to the sebaceous glands. These glands are responsible for producing an oily substance called sebum, which lubricates the skin and hair. When the duct of the sebaceous gland becomes blocked, such as due to trauma, infection, or excessive production of sebum, it leads to the formation of a cyst. Hormonal changes, genetic predisposition, and certain medical conditions, such as acne or basal cell nevus syndrome, can also contribute to the development of sebaceous cysts.
The symptoms of a sebaceous cyst usually include a small, round, or oval-shaped lump beneath the skin that is smooth to the touch. It can range in size, from a few millimeters to several centimeters. The cyst may be white or yellowish and appear filled with a thick, cheesy material called keratin. In some cases, the cyst may become tender, red, and inflamed, indicating an infection. If the cyst ruptures, it can cause pain, swelling, or a foul-smelling discharge.
Fortunately, most sebaceous cysts do not require treatment unless they cause discomfort or are cosmetically bothersome. However, it is crucial to avoid squeezing or attempting to pop the cyst at home, as this can increase the risk of infection and scarring. If the cyst is causing pain or becomes infected, seeking medical attention is recommended.
Treatment options for sebaceous cysts vary depending on the severity and location of the cyst. In cases where the cyst is not infected and causing no discomfort, a watchful waiting approach may be recommended. In such situations, it is important to monitor the size and appearance of the cyst for any changes and report them promptly to a healthcare professional.
If the cyst becomes inflamed or infected, the primary treatment involves incision and drainage. A healthcare provider will make a small cut on the cyst and drain the contents, relieving the discomfort and reducing the risk of infection. Oral antibiotics may be prescribed to treat any existing infection or prevent any potential ones.
In recurring or chronic cases, surgical removal of the cyst may be recommended. During this procedure, the entire cyst sac is carefully excised to reduce the chances of the cyst reoccurring. It is important to note that self-attempted removal or home remedies, such as applying heat or topical creams, should be avoided, as they are ineffective and can increase the risk of complications.
In conclusion, sebaceous cysts are common skin growths that develop due to blockage or damage to the sebaceous glands. While usually harmless, they can cause discomfort and concern for some individuals. If a sebaceous cyst becomes infected or causes pain, seeking medical attention is crucial. Treatment options vary depending on the severity of the cyst and can range from watchful waiting to incision and drainage or surgical removal. Importantly, self-attempted removal or home remedies should be avoided to prevent complications. Consulting with a healthcare professional is necessary to determine the most suitable treatment approach for each individual case.
