Rash on penis

The penis is the male reproductive organ. If a rash appears on the penis, there are many reasons. It may be genital warts, balanitis, or pearly rash. Since the affected area is relatively special, it is best to go to the hospital for relevant examinations. After the cause is found out, symptomatic treatment should be given. Do not take it indiscriminately, otherwise it will aggravate the condition.

What are the symptoms of balanitis?

1. Acute superficial balanitis

Edema, erythema, erosion, exudation and bleeding, and blisters may appear in severe cases. If secondary infection occurs, ulcers may form, covered with purulent exudate. Conscious pain and tenderness. Some patients may have mild systemic symptoms, such as fatigue, weakness, low fever, and enlarged inguinal lymph nodes.

2. Annular ulcerative balanitis

It may be the early mucosal damage of Reites disease or it may be related to the long-term irritation of smegma. The clinical manifestations are erythema on the glans penis, which gradually expands and becomes ring-shaped or multi-ring-shaped, and may later form shallow ulcers. Secondary infection may worsen symptoms and cause the ring to lose its ring-like characteristics.

3. Candidal balanitis

Caused by Candida infection. The clinical manifestations are erythema, smooth surface, slight desquamation around, scattered papules or pustules around, which slowly expand to the surrounding areas. In the acute phase, edema, erythema, erosion, and exudation may occur.

4. Plasma cell balanitis

It is more common in middle-aged patients. The glans penis develops localized, infiltrative, dark reddish-brown patches with clear boundaries and a smooth surface. There are many small red spots or erosions that bleed easily but do not form ulcers. Histopathology is diagnostic and is characterized by a band-like infiltration of inflammatory cells in the superficial dermis, interspersed with a large number of plasma cells.

5. Amebic balanitis

When the foreskin and glans become inflamed, the barrier function of the epithelium is lost, making it easy for amoeba infection to occur. The clinical manifestations are glans erosion, shallow ulcers, obvious tissue necrosis and pain.

6. Mica and keratotic pseudoepitheliomatous balanitis

The rash is infiltrated and hypertrophic, with local hyperkeratosis and mica-like crusts, which are silvery white. The glans penis loses its normal elasticity and gradually shrinks.

7. Trichomonas balanitis

It is a mild, temporary erosive glans inflammation caused by Trichomonas infection. Initially, erythema and papules appear on the glans penis with clear boundaries and gradually expand in scope. There may be small blisters ranging in size from needle tips to millet grains on the erythema. The blisters may expand and fuse with each other to form a mild erosive surface.
