The possible causes are as follows: 1. Penile glans inflammation. There may be erythema of various shapes on the glans penis. If it is a bacterial infection, there may be erythema with unclear boundaries, most of which are accompanied by pain and exudation. If it is a bacterial or trichomonal infection, during the onset of the disease, erythema of fixed shape can be seen, and the boundaries around the erythema are clear. There is no exudation in non-acute symptoms. However, acute symptoms may have changes in pain and exudation, and may be accompanied by more milky white secretions in some areas. It is necessary to carry out corresponding examinations of secretions. After confirming the cause of the disease, symptomatic treatment is required.

2. Fixed drug rash. It is more common in drug allergy, and is a local manifestation after systemic reaction. In addition to the erythema on the glans penis, it can also be seen on the genitals, or on the skin of the whole body, and erythema in other parts of the body, which may be accompanied by itching. Relevant tests are needed. If it is clearly caused by allergy, anti-allergy treatment is necessary.

Due to long-term long foreskin and prepuce, bacterial infection may gradually occur in some parts. At this time, erythema with clear borders on the glans penis will appear. Acute symptoms may include pain and exudation. However, the onset of the disease may be accompanied by a lot of secretions, generally without obvious pain or itching, and milky white or cheese-like milky white secretions can be seen on the surface. It is recommended to conduct a bacterial test. If bacterial infection is confirmed, further treatment is required. 2. Fixed drug rash, due to allergic reactions caused by taking some drugs orally, fixed erythema may appear in many parts of the human body. Sometimes it can also be mainly manifested on the genitals, with clear erythema, often with a confirmed history of taking allergic drugs, and accompanied by itching or erythema in other parts of the body. It is recommended to go to the dermatology department for further medical treatment to determine whether there is a fixed drug rash caused by drug allergy.

It is recommended to conduct relevant etiological tests. After diagnosing glansitis, anti-infective treatment is required, and local environmental hygiene must be maintained and regular cleaning is performed. 2. Fixed drug rash.

It can recur, sometimes without any active symptoms, but sometimes with itching or local exudation, etc., and can also be accompanied by erythema in other parts of the body. Anti-allergic treatment is required after diagnosis. 3.
