Sand Red spots on the glans may be related to factors such as allergic reactions, infectious factors, physical irritation, local skin diseases, or balanitis. The symptoms can be relieved by keeping clean, applying topical or oral medications, avoiding irritation, or seeking medical treatment.
1. Allergic reaction
Contact with chemicals such as detergents, condoms or underwear materials may cause skin irritation on the glans. Typical manifestations are scattered red papules with itching, and edema may occur in severe cases. It is recommended to immediately stop using the suspected allergen, wash with warm water and apply mometasone furoate cream topically. Wearing breathable cotton underwear can help reduce friction and irritation.
2. Infectious factors
Candida albicans infection is common in patients with diabetes and manifests as glans erythema accompanied by white cheese-like discharge. Microscopic examination of secretions is required for diagnosis, and clotrimazole cream combined with fluconazole capsules can be used as directed by the doctor. Bacterial infection may cause purulent changes, and it is necessary to conduct pus culture and then select sensitive antibiotics such as cefixime dispersible tablets.
3. Physical stimulation
Mechanical damage may occur from excessive cleaning, strenuous sex, or external friction. This type of red dot is distributed in a dot-like manner with clear borders and usually has no secretion. After suspending sexual intercourse, cold compress with 0.9% sodium chloride solution can relieve symptoms. If symptoms persist for 3 days, the possibility of infection must be ruled out.
4. Skin diseases
Skin diseases such as psoriasis and lichen planus may cause special-shaped red spots on the glans. If there are silvery white scales on the surface of psoriasis skin lesions, calcipotriol ointment can be used ； Lichen planus manifests as purple-red polygonal papules and needs to be diagnosed through skin biopsy and treated with triamcinolone acetonide and econazole cream.
5. Balanitis
People with excessive foreskin are prone to secondary foreskin balanitis, which manifests as annular erythema with burning sensation. In the acute stage, it is necessary to soak in 1:5000 potassium permanganate solution and apply compound ketoconazole ointment. For recurrent cases, the authors recommend circumcision after infection control, and screening for underlying diseases such as diabetes.
Daily care should be taken to keep the perineum clean and dry, avoid using alkaline lotions, and choose fragrance-free hygiene products. Wear loose, breathable cotton underwear to reduce local friction, change underwear every day and wash in boiling water. Eat less spicy food and drink an appropriate amount of water to promote metabolism. If the red spots do not subside for 3 days, expand in area, or are accompanied by ulcer exudation, you should go to a dermatology or urology department in time, and do not use hormonal ointments on your own for a long time.
