What does it mean if a hard lump develops below the earlobe?

Generally, a hard lump under the earlobe may be related to factors such as allergies, scar hypertrophy, folliculitis, sebaceous cysts, or swollen lymph nodes. It is recommended that patients promptly visit a hospital for examination and receive symptomatic treatment under a doctor's guidance. Specific explanations are as follows:

1. Allergy: When the skin below the earlobe comes into contact with allergens, such as cosmetics, jewelry materials, or cleaning products, an allergic reaction may occur, causing redness, swelling, itching, and possibly the formation of a hard lump.

2. Scar hypertrophy: Previous trauma or surgery below the earlobe may cause connective tissue proliferation and the formation of scar tissue. Generally, no specific treatment is required, but surgical excision may be considered if the scar affects appearance or causes discomfort.

3. Folliculitis: Bacterial infection of the hair follicles on the earlobe may cause inflammation, resulting in a hard, swollen, painful lump, which may be accompanied by itching. It is recommended that patients use medications such as mupirocin ointment, fusidic acid sodium ointment, or compound polymyxin B ointment under a doctor's guidance to relieve symptoms.

4. Sebaceous cyst: Blockage of the sebaceous gland duct may lead to accumulation of sebum, causing the cystic epithelium to expand and form a cyst, which may be accompanied by redness and pus discharge. Patients should take medications such as amoxicillin capsules, cefuroxime axetil tablets, or roxithromycin dispersible tablets as advised by their doctor to aid recovery.

5. Swollen lymph nodes: When the body experiences infection or inflammation, lymph nodes may swell, causing a hard lump near the earlobe, possibly accompanied by systemic symptoms such as fever and fatigue. Patients should promptly follow medical advice to take medications such as erythromycin tablets, prednisolone tablets, or ibrutinib capsules for treatment.

In daily life, it's important to develop healthy habits, avoid long-term smoking and staying up late, and ensure proper skin cleansing.
