Bumps growing at the base of the earlobe can be considered as sebaceous cysts or enlarged lymph nodes. 1. Sebaceous cysts: also known as acne, caused by sebaceous gland excretory tube blockage, the sebaceous gland cystic epithelium in the earlobe area is swollen by the content, which can form a slow-growing cyst, and the inside of the cyst can be seen as bean dregs-like secretion, and if it is secondary to infection, it can cause localized pain, redness and swelling. 2. Enlarged lymph nodes: when inflammation occurs in and around the ear, it can spread to the lymph nodes in the ear area, causing enlarged lymph nodes and pressure pain; if there is a malignant tumor or hematological disease and other tumor cells metastasize to the lymph nodes in the ear, it can also cause enlarged lymph nodes, which may have no pressure pain. When you find lumps at the root of the earlobe, you can consult a doctor in time to clarify the nature of the lumps, identify the cause of the disease, and then carry out targeted treatment.
