A boy has small bumps on his scrotum and itches

Small bumps and itching on the scrotum may be caused by diseases such as eczema, scrotal dermatitis, tinea cruris, folliculitis or contact dermatitis. It is recommended to seek medical treatment promptly for a clear diagnosis and avoid scratching from aggravating symptoms.

1. Eczema

Scrotal eczema may be related to factors such as local moisture, sweating, allergies, etc. It manifests as red papules accompanied by severe itching. Exudation may occur in the acute phase, and the skin may become thickened and rough in the chronic phase. Topical corticosteroids such as hydrocortisone butyrate cream and mometasone furoate cream can be used as directed by the doctor. Mupirocin ointment needs to be used in conjunction with infection. It is necessary to keep the area dry every day and avoid hot water scalding.

2. Scrotal dermatitis

Long-term friction or chemical irritation may lead to scrotal dermatitis, which manifests as well-circumscribed erythema, scaling, and itching. Treatment needs to eliminate the inducements and use compound dexamethasone acetate cream as directed by the doctor. In severe cases, loratadine tablets can be taken orally for a short period of time. It is recommended to wear loose cotton underwear and avoid using alkaline detergents for cleaning.

3. Tinea cruris

Tinea cruris caused by fungal infection can spread to the scrotum and manifest as annular erythema with scaly edges and obvious itching. Diagnosis requires fungal microscopy, and topical bifonazole cream or terbinafine cream can be used. In stubborn cases, oral itraconazole capsules are required. During treatment, personal clothing must be disinfected simultaneously and avoid sharing towels with others.

4. Folliculitis

Staphylococcus aureus infection may cause scrotal folliculitis, which appears as red pustules that are tender to tenderness. For mild cases, fusidic acid cream can be used externally, and for those with multiple cases, cefuroxime axetil tablets should be taken orally. Pay attention to disinfecting shaving tools every day to avoid squeezing rashes.

5. Contact dermatitis

When you are allergic to underwear materials or detergents, dense blisters with burning and itching may appear on the scrotum. In the acute stage, wet compress with normal saline, take cetirizine hydrochloride tablets orally as directed by the doctor, and apply calamine lotion externally. It is recommended to change to hypoallergenic detergent and rinse new underwear thoroughly before wearing it.

You should choose breathable and sweat-absorbent cotton underwear for daily use to avoid sweat soaking after sitting for a long time and strenuous exercise. When taking a bath, the water temperature should not exceed 40°C, and strong scrubbing with soap is prohibited. You need to avoid spicy and stimulating foods in your diet and maintain a regular schedule. If symptoms persist or symptoms such as ulceration and pus discharge appear, you must seek medical attention from a dermatologist immediately.
