Pictures of tinea on the penis

Ringworm is a very common skin disease that can be divided into many types and distributed in many parts of the human body. Some men have noticed that they have ringworms on their male genitals, and they are definitely concerned about the cause. So, what is the cause of ringworms on male genitals?

There are two main types of tinea in male genital skin. One is tinea corporis, which is caused by bacterial infection. The main manifestation is the appearance of annular macules on the glans penis, with significant inflammation at the edges, relief of inflammation in the middle, and gradual spread. It can be treated with topical antifungal creams, such as sodium cyanide miconazole ointment, terbinafine hydrochloride gel, etc.

Symptoms of ringworm

Because there are many types of pathogenic bacteria that cause tinea corporis, and each patient has different physical constitutions and immunity, as well as different living habits, the clinical manifestations of tinea corporis vary.

When highly pathogenic bacteria invade the thin stratum corneum on the surface of the body, it can cause mild inflammation, resulting in lesions such as erythema, papules, and blisters, followed by scaling, often in a ring shape, so it is also called ringworm or ringworm. At the beginning, the lesions are separated and spread, and when they gradually expand, they can combine and overlap with each other, and sometimes even spread to the whole body, especially for some patients with immunodeficiency or who use immunosuppressants, corticosteroids, anti-tumor drugs, etc., the skin lesions can be very common. Due to the function of the body's defense, the center of the ring-shaped lesion can be smooth and flaky, the edge is raised in a ring shape, there will also be active erythema, papules and blisters or scaling, and the center is flat and flaky or has pigmentation.

The second is psoriasis, which is an inflammatory disease. The actual cause of the disease is unclear. The clinical symptoms are bright red macules on the male genital skin with silvery scaling on the surface. It can be treated with topical application of calcipotriol cream.

Psoriasis symptoms

Initially, it is an inflammatory red papule, about the size of millet to mung bean, and then gradually expands or coalesces into a reddish-brown soft plaque with clear boundaries, inflammatory reddish surroundings, obvious base infiltration, and a double layer of dry gray or silvery scaling on the surface. Gently shave off the surface scaling, and gradually a layer of dark red shiny transparent film will appear, which is called the film state. If the film is scraped off again, small blood spots will appear, which is called the punctate bleeding state. White scaling, shiny film and punctate bleeding are the key features of confirmed psoriasis, which are called the triad. Skin lesion shapes: dot-shaped, coin-shaped, topographical, ring-shaped, strip-shaped, generalized, seborrheic dermatitis-like, eczema-like, shell-shaped, lichen planus-like, diffuse hypertrophic, wart-like, etc.
