Red papules in the coronal sulcus of the glans penis

What is the cause of corona groin papules? The importance of male reproductive organs does not need us to say more, but many men do not pay much attention to medical care in their daily lives, which makes it very easy for them to develop some diseases, such as corona groin papules. So what is the cause of corona groin papules? How to prevent it? Let the editor give you a detailed introduction.

1. What is the cause of coronal groin papules?

Coronal groin papules often occur in the vulva and anus of men and women. Because the affected areas are relatively private, they cause great psychological burden to patients and even affect their normal diet, living and learning. This kind of symptom is easily misdiagnosed and is often misdiagnosed as pseudo-warts. The papules in the coronal groin may be pearly papules. Pearly papules are attributed to genetic mutations in physiological growth and development. They are neither tumors nor genital infections. The clinical manifestations are white, skin-colored or light red papules, which are combined with each other and arranged in one or several rows along the coronal groin of the glans penis. This disease generally does not require treatment. Clinical medicine believes that it is related to long foreskin and inflammatory irritation. If it is convenient, you can go to the hospital for examination and treatment to reduce unnecessary worries.

2. What is papule?

Papules are localized protrusions above the skin, ranging from as small as a needle to as large as a soybean. They may be erect or flat, smooth or warty in structure, or have melanin the same color as the surrounding skin (those with a diameter exceeding 1 cm are called soft spots). Many skin diseases begin with papules, so papules should be closely observed and diagnosed.

3. How to prevent papules

Keep the environment, house and sanitation good to prevent the growth of insects that cause the disease; spray insecticides outdoors to kill harmful arthropods such as bed bugs, lice, mosquitoes, etc. The disease is a common disease in children in autumn and spring, especially after playing outdoor games. Pay attention to sanitation and hygiene, kill mosquitoes, fleas, lice, bed bugs, etc., and avoid eating allergenic foods to reduce the occurrence of the disease. Try not to scratch to prevent secondary infection. The rash will disappear naturally. Giving appropriate medication can improve symptoms and speed up the disappearance of the rash.

Pathogenic factors of papules

Many skin diseases can manifest as papules. Some are manifested by papules alone, while others are accompanied by other skin lesions. The lesions caused by papules are located in the epidermis or dermis, so from a pathological point of view, the mechanism of papule formation is the deposition of certain metabolites in this area; or localized proliferation of epidermal or dermal cells; or inflammatory edema and infiltration of various cells in this area can manifest as papules.

Accumulation of metabolites: For example, the papules of amyloidosis of the skin are caused by the accumulation of tapioca starch-like protein in the dermal papilla. The papules of edematous lichen are caused by the accumulation of a lot of old protein in the upper dermis. The papules of colloid miliary papules are caused by the invasion of homogeneous colloid hypoechoic areas in the dermal papillary layer. What is the cause of corona sulcus papules?

Papules caused by localized proliferation of epidermal or dermal cells, such as common warts, flat warts, and psoriasis, are all caused by excessive proliferation of epidermal cells, resulting in localized protrusions of the epidermis. Dermatofibroma and dermatofibroma are also caused by the proliferation of epidermal cells to produce papules.

Papules caused by localized edema of the epidermis are common in eczema, contact dermatitis, etc. Because papules are caused by various somatic cells invading the epidermis or dermis, they have their heterogeneity in clinical medicine. Purulent inflammatory papules are mainly infiltrated by neutrophils; diffuse inflammatory papules are mainly infiltrated by reticulocytes; papules caused by allergic factors are mainly infiltrated by eosinophils; tuberculous papules are infiltrated by epithelioid cells and reticulocytes; syphilitic papules are infiltrated by plasma cells; and xanthomatosis is characterized by foam cell infiltration. The pathogenesis of papules is related to the pathogenic factors.
