What is the reason for the red spot on the penis head when it is erect?

The first reason for the red spots on the glans is balanoposthitis. It is necessary to combine the symptoms to determine whether it is caused by inflammation.

If there is an infection or inflammation, it will usually be accompanied by swelling or itching, or secretion. In addition to the red spots on the glans, there will also be some milky white secretions, such as urine scale, etc. This is a factor to consider. Because some of these small red spots are due to bacterial infections, some are due to candidal infections, and other various reasons.

Therefore, it is recommended that patients go to the hospital's outpatient urology department or men's department for a specialist examination, and some may need to go to the hospital's outpatient dermatology department for an examination. In summary, if there are patients with long foreskin or prepuce, as much as possible, it is necessary to ensure that the secretions in the prepuce are cleaned every day to reduce the possibility of inflammation.

Main performance

1. Subacute atrophic glansitis

It is common in young people with active sexual life. The infection bacteria are generally the same as those of the sexual partners. At the beginning of the disease, part of the skin is red, and the active glans penis has a burning and itching sensation. Acute symptoms: When the foreskin is opened, the glans penis can be seen to have edematous erythema, erosion, exudate and bleeding. In severe cases, blisters may appear. If secondary infection occurs, ulcers may occur, covered with purulent exudate, and some pain and tenderness are obvious. Some patients may have mild systemic symptoms, such as fatigue and drowsiness. During the onset of the disease, only the inner plate of the foreskin and the coronal sulcus are red and blocky, or cracked like broken porcelain.

2. Annular rupture of glans

It may be the initial mucosal damage of Reites disease, or it may be related to the long-term irritation of urine scale. The clinical symptoms are erythema on the glans penis, which gradually expands and becomes annular or multi-annular, and then shallow ulcers may occur. The key feature of the disease is one or more annular lesions on the glans penis, with a bright red erosive surface in the middle and a white thin band on the edge, connected into a ring. If secondary infection occurs, the symptoms may be aggravated and lose its annular characteristics.

3. Trichomonas balanoposthitis

Caused by trichomonas infection, Candida albicans is the most common. Clinical symptoms include prepuce hyperplasia and erythema of the glans penis, smooth surface, a small amount of scaling nearby, scattered papules or pustules around, and slowly expanding to the periphery. Acute symptoms may present with edema erythema, erosion, and exudate. In severe cases, it may spread to the male genitals, scrotum, thigh and groin. It is mostly caused by sexual transmission, and can also be secondary to diabetes, active hepatitis, and long-term antibiotic or hormone treatment.
