What causes red scar lumps on the chest?

In general, the appearance of red scar nodules on the chest may be caused by factors such as keloid-prone constitution, improper wound care, folliculitis, acne, or herpes zoster. Patients can receive symptomatic treatment based on the specific cause. Detailed analysis is as follows:

1. Keloid-prone constitution: Individuals with a keloid-prone constitution may develop scar nodules after skin injury on the chest. Patients can visit a reputable medical facility to remove red scar nodules through laser therapy.

2. Improper wound care: Incorrect or delayed wound care may lead to wound infection and worsened inflammation, resulting in red scar nodules on the chest. Under a doctor's guidance, patients may use medications such as mucopolysaccharide polysulfate cream or recombinant human basic fibroblast growth factor gel.

3. Folliculitis: Folliculitis is an inflammatory reaction around hair follicles, usually caused by bacterial infection. If it affects the skin of the chest, it may lead to scarring, presenting as red scar nodules. Under medical guidance, patients may use topical medications such as mupirocin ointment or fusidic acid sodium cream.

4. Acne: Infection with *Propionibacterium acnes* on the chest may trigger an inflammatory response leading to acne, which in turn causes red scar nodules. Patients may use medications such as tretinoin cream or sulfur ointment under a doctor’s supervision.

5. Herpes zoster: Infection with varicella-zoster virus may cause rashes. If the rash is not promptly treated, it may result in red scar nodules. Under a doctor’s direction, patients may use medications such as compound dexamethasone cream or vitamin E lotion.

If red scar nodules appear, prompt medical consultation is recommended to avoid delays in treatment.
