A sudden and rapid growth of a comedo is usually indicative of severe localized signs of infection and requires prompt anti-infective treatment or surgical removal. Pink tumors are usually sebaceous cysts. If rapid growth occurs within a short period of time, it is necessary to consider the presence of secondary infection at the site of the cyst. Need to use erythromycin ointment, erythromycin capsules and other drugs for external or internal antibacterial drug treatment. If the sebaceous cyst grows too fast or has caused pressure damage to the surrounding connective tissues, it is recommended to perform surgical resection after anti-inflammatory treatment as soon as possible, which can quickly remove the cysts and the surrounding infected lesions, and thus provide a radical cure. After the abnormal growth of acne, it is necessary to consult a doctor in time and choose the appropriate treatment method and medicine under the doctor’s guidance.
