The most common clinical condition that can cause a bag to grow inside the earlobe is acne, or sebaceous cyst. Sebaceous cysts are more likely to occur in patients who are obese, have high blood sugar, high blood lipids, stay up late, get irritated, eat greasy and spicy foods. In patients with earlobe powdery tumor, it is a benign lesion that is not contagious, hereditary, or malignant. Clinically, once a patient is considered to be a pink tumor, if local pain occurs, anti-inflammatory treatment with antibiotics can be administered first. In some patients, if the tumor is not very large, it may slowly absorb and become smaller as the inflammation subsides. If the swelling is no longer painful after local anti-inflammatory treatment but does not recede significantly, surgical excision can be considered. The entire cystic skin will be removed under local anesthesia to avoid postoperative recurrence.
