Epidermal or sebaceous cysts are generally circular and elastic cysts that surface on the skin and often have a pimple in their central part. To distinguish these cysts from adenopathies, specialists examine it to see if the skin slides over the cyst. If this is not the case and the skin moves together with the cyst, it is called a sebaceous gland cyst. The epidermal cyst can vary in size by several centimetres. Most often, these cysts cannot be treated topically as they do not respond to oral medications or creams and they can be treated surgically under the following circumstances: The size of the cyst is very large. It creates a deformity in the atrial lobe. It is painful. Bothersome in everyday life. It is repeatedly swollen. In many cases,these sebaceous cysts are asymptomatic and no intervention is needed; you just need to check them from time to time to see how they develop. They can change or decrease in size, but since they are encapsulated glands, they often grow back over time.
