Introduction
Painful yellow pustules and ulceration on the lips are usually caused by folliculitis, cheilitis, or angular cheilitis, and appropriate medication should be selected based on the specific condition. Besides these common causes, other factors such as herpes simplex, herpes zoster, or hand-foot-and-mouth disease may also be responsible. In such cases, patients should seek medical attention promptly to avoid delaying treatment.
Yellow pus-filled blisters with ulceration on the lips are usually caused by folliculitis, cheilitis, or angular cheilitis, and treatment should be selected based on the specific condition. Detailed analysis is as follows:
1. Folliculitis
When hair follicles in the lip area become infected, red rashes appear locally, often with pus heads, accompanied by symptoms such as pain, pus discharge, and exudation. This condition is typically related to bacterial infection. In such cases, topical medications like erythromycin ointment or mupirocin ointment should be used under a doctor's guidance to alleviate symptoms.
2. Cheilitis
Cheilitis refers to inflammatory lesions affecting the skin and mucous membranes of the lips, commonly associated with bacterial infection. Patients may develop pustules on the lips, accompanied by ulceration, scaling, and pain. It is recommended that patients take medications such as amoxicillin capsules or cefixime capsules under medical supervision.
3. Angular Cheilitis
This is typically an inflammatory condition occurring at the corners of the mouth, often related to bacterial or viral infections. Patients may develop pustules at the mouth corners, accompanied by pain, dryness, and cracking of the lips. Treatment may include oral tetracycline tablets or vitamin B2 tablets under a doctor’s guidance.
In addition to the common causes mentioned above, other factors such as herpes simplex, herpes zoster, or hand-foot-and-mouth disease may also be responsible. Patients should seek timely medical care to avoid delays in treatment.
