Introduction
Lumps inside the earlobe are commonly caused by sebaceous cysts, folliculitis, hypertrophic scarring after ear piercing, swollen lymph nodes, or lipomas. The skin of the earlobe contains active sebaceous glands; if the glandular ducts become blocked, sebum cannot be discharged and may form a cyst. This presents as a firm, smooth-surfaced lump, usually painless. However, if secondary infection occurs, it may lead to redness, swelling, and pain.
Lumps inside the earlobe are commonly caused by conditions such as sebaceous cysts, folliculitis, hypertrophic scarring after ear piercing, swollen lymph nodes, and lipomas. The specific details are as follows:
1. Sebaceous cyst: Overactive sebaceous glands beneath the skin of the earlobe can lead to cyst formation if the gland's duct becomes blocked, preventing sebum from being discharged. This results in a firm lump with a smooth surface, usually painless. If secondary infection occurs, redness, swelling, and pain may develop. Squeezing should be avoided to prevent spreading the infection.
2. Folliculitis: Bacterial infection of hair follicles in the earlobe can cause folliculitis, leading to small red bumps that may be accompanied by mild pain or itching. A white pus-filled tip may appear at the center of the bump. It often results from inadequate skin hygiene or scratching. Symptoms typically improve with proper local cleansing.
3. Post-piercing hyperplasia: After ear piercing, localized skin overgrowth may occur due to inflammatory irritation or individual predisposition (such as having a scar-prone constitution). These lumps are firm, may appear reddish or close to skin color, and sometimes cause itching. They may gradually enlarge over time. Avoiding irritation is important to prevent worsening.
4. Swollen lymph nodes: Lymph nodes behind the ear or near the earlobe may swell in response to infections such as throat or ear inflammation. The lump is usually movable and tender to touch. Once the underlying infection resolves, the lymph node typically shrinks gradually. Treating the primary infection is essential.
5. Lipoma: Composed of fatty tissue, lipomas are soft, well-defined lumps that are generally painless and grow slowly. They form due to local fat accumulation and are usually harmless. If the lipoma becomes large enough to affect appearance, treatment options may be considered.
When a lump is detected in the earlobe, monitor its size, texture, and whether pain or other symptoms are present. If the lump continues to grow, causes significant pain, or shows signs of infection, medical evaluation should be sought promptly to determine the cause.
