Sebaceous cysts are commonly known as "powder tumors". They are mostly distributed in the skin or subcutaneous tissues of the head, trunk, or genitals. They have a complete capsule before they are ruptured and have adhesions to nearby tissues, but they can be pushed. Mainly because the sebaceous gland excretory duct is blocked, the sebaceous gland cystic epithelium is swelled by the increasing content of the retention cyst. It is a slowly growing benign lesion. There are white okara-like secretions in the sac. Sebaceous cysts protruding from the surface of the skin generally have no conscious symptoms, such as pain and suppuration in secondary infections. Patients with a long course of disease may also develop cancer. Treatment should be surgical resection. Surgical resection should try to remove the cyst and the capsule completely. If the capsule is incomplete, it is easy to recur.
