The harm of sebaceous cysts is relatively small, may cause local compression, affecting aesthetics or secondary infection, etc., the prognosis is relatively good. Sebaceous cysts are benign skin diseases, mainly due to localized accumulation of sebum, and generally do not cause obvious clinical symptoms. Larger sebaceous cysts may cause localized compression of skin tissues, resulting in slight discomfort; cysts on the face and other daily exposed areas may affect the skin’s aesthetic appearance. Sebaceous cysts may be secondary to localized bacterial infections, which may cause discomfort due to localized redness, swelling, and tenderness of the skin. The prognosis of sebaceous cysts is usually good after surgical removal of the cysts. For secondary infections, anti-infective treatment should be carried out under the guidance of a physician in a timely manner, and appropriate antibiotics should be selected according to the results of the bacterial drug sensitivity. For sebaceous cysts, it is recommended to consult a doctor in a timely manner and standardize the treatment under the guidance of a professional doctor in order to avoid delaying the condition.
