Introduction

The term "egg skin" refers to the scrotal skin. Small bumps on the scrotal skin may be caused by friction, poor hygiene, genital herpes, balanitis, or sebaceous cysts, and appropriate management depends on the specific situation. When small bumps appear on the scrotal skin, patients should maintain local cleanliness, avoid scratching or squeezing the area, seek timely medical attention, and undergo targeted treatment after a definitive diagnosis.

The term "egg skin" refers to the scrotal skin. Small bumps on the scrotal skin may be caused by skin friction, poor hygiene, genital herpes, scrotal dermatitis, or sebaceous cysts. Appropriate management depends on identifying the specific cause.

1. Skin Friction: The skin of the scrotal area is relatively sensitive. When underwear is made of coarse or tight-fitting material, it can cause frequent friction against the scrotal skin, potentially leading to thickening of the skin's keratin layer and the formation of small bumps. It is recommended to choose undergarments that are soft, loose-fitting, and breathable to reduce friction.

2. Poor Hygiene: The scrotal area tends to sweat easily, and sweat, dirt, and shed skin cells can accumulate on the skin surface. If not cleaned promptly, this can lead to skin infections and the appearance of bumps. It is recommended to wash the scrotal area daily with warm water, ensuring thorough cleaning, including the folds of the scrotal skin.

3. Genital Herpes: Genital herpes is caused by infection with the herpes simplex virus and is primarily transmitted through sexual contact. The scrotal skin may develop clustered or scattered small blisters. During an outbreak, patients should rest adequately and keep the affected area clean and dry. Oral antiviral medications such as acyclovir or valacyclovir are recommended under a physician's guidance for treatment.

4. Scrotal Dermatitis: Often caused by bacterial or fungal infections, scrotal dermatitis may present with red patches, papules, scaling, and symptoms such as itching or pain. It is recommended to use topical medications such as ketoconazole cream or terbinafine cream under a physician's guidance to treat the inflammation.

5. Sebaceous Cyst: Blockage of the sebaceous gland ducts on the scrotal skin can prevent the normal drainage of sebum, leading to accumulation within the gland and the formation of a cyst. This may result in round or oval-shaped lumps on the scrotal skin. Smaller sebaceous cysts generally require no treatment. However, if the cyst is large or becomes infected or painful, consultation with a physician regarding possible surgical removal is advised.

When small bumps appear on the scrotal skin, it is important to maintain local cleanliness, avoid scratching or squeezing the area, seek timely medical evaluation, and receive targeted treatment based on a clear diagnosis.
