What is penile ulcer?

The incidence of penile ulcer is still very high, but many people do not know what disease causes this symptom, so they cannot take corresponding treatment measures in the early stage. In fact, the causes of this disease are quite diverse. Most of them are related to bacterial infection in the penis, which will cause inflammatory reaction.

Penile ulcers indicate the presence of balanitis. The causes of balanitis can be infectious or non-infectious. Infectious balanitis is more common in clinical practice. Infectious balanitis is often caused by unclean sexual intercourse, infection with chlamydia, trichomonas, candida albicans, mycoplasma, gonorrhea or other bacteria.

Non-infectious factors are mostly due to the foreskin being too long and not being cleaned enough. The dirt between the foreskin and the glans penis, that is, the smegma, will slowly accumulate and stimulate the local foreskin and mucous membrane to cause inflammation, leading to penile ulcers.

In case of penile ulcer, you need to pay attention to local hygiene and clean the glans and foreskin every day. If the foreskin is too long, you need to treat it in time and perform penile circumcision when necessary. At the same time, it is also necessary to clean the smegma in time.

Males aged around 20-30 years. The damage mainly occurs at the junction of the edge of the glans and the coronal sulcus and/or the frenulum. The damage is a papule of 1-3mm in size, with larger damage on both sides of the frenulum. The top of the papule is round and smooth, and some papules are hairy or thread-like. The papules are mostly unfused and densely arranged in one or more rows. They are obvious on the dorsal side of the glans and may partially or completely surround the glans. The color of the damage is mostly pearly white, a few are light red or skin-colored, and some may appear slightly red and swollen.

There is no tenderness, no rupture, and the patient has no conscious symptoms. Histopathological examination of vulvitis shows hyperkeratosis, mild to moderate hyperplasia of the epidermis, normal basal layer, slight hyperplasia and density of collagen fibers in the dermis, varying degrees of hyperplasia and dilation of dermal papillary capillaries, a small amount of lymphocyte infiltration around, and no concave cells.

The key point of differential diagnosis of penile inflammation is that the lesions in the former are limited to the edge of the glans, the number of lesions is large, they are pearly white, the surface is smooth, the lesions do not increase with the extension of the disease course, and the acetic acid test is negative; while the lesions in the latter are not limited to the edge of the glans, they are mostly single and scattered, the lesions are large, the surface is not smooth, and they are mostly cauliflower-shaped. They gradually increase with the extension of the disease course, the acetic acid test is positive, and the tissue pathological examination shows concave cells.
