Clinical manifestations of scrotal eczema can be categorized into erosive and dry types.
1. Erosive type presents as acute or subacute onset. Initial symptoms include skin erythema and itching, progressing to papules and vesicles. Scratching causes profuse serous exudate, followed by crusting and desquamation.
2. The dry type manifests after the condition becomes chronic. The skin thickens, roughens, and dries out, with desquamation forming a lichenified appearance. The skin color darkens to reddish-brown or deep brown, accompanied by intense itching that worsens at night or during emotional stress.
Intense scrotal itching that cannot be scratched
Due to the delicate and sensitive skin of the scrotal region, men often experience itching when scrotal eczema develops. Itching is the primary symptom, frequently leading to the discovery of this condition. As the disease progresses, itching intensifies, and scratching fails to provide relief. Severe cases can disrupt sleep and work.
Scratching or inappropriate irritation can cause pain or secondary infections. Men should never feel embarrassed to seek help due to the sensitive location of the scrotum. Avoid self-treatment with iodine, antifungal solutions, garlic, or other disinfectants. Scratching, rubbing, hot washing, soap, salt water, or alkaline solutions are strictly prohibited.
Scrotal eczema is a stubborn and difficult-to-cure condition, making prevention essential. Eczema can appear anywhere on the body, typically in symmetrical patterns. During acute phases, it presents with redness, swelling, or blisters. Symptoms often persist long-term, progressing to chronic eczema where the rash thickens, develops papules and scaling, and paradoxically becomes "dry rather than wet."
How to Prevent Scrotal Eczema
1. Wear loose, comfortable underwear, preferably made of pure cotton. Avoid tight-fitting undergarments. Change and wash underwear promptly, especially after exercise.
2. Dietary recommendations: Increase intake of fresh vegetables and fruits. Avoid or minimize consumption of pungent and spicy foods.
3. When experiencing scrotal itching, seek prompt treatment. Avoid excessive scratching or hot washing, especially with soapy water.
