What should you know about impetigo on scrotum?

Impetigo on the scrotum is a contagious bacterial skin infection that needs gentle care and medical assessment, especially because genital sores can have several causes. It may begin where the skin has been scratched, irritated or broken, then form small blisters or shallow sores that leak fluid and develop a yellowish or brown crust. A clinician can check whether the appearance fits impetigo and whether another infection, dermatitis or an ulcer needs different treatment. Avoid sexual contact until the diagnosis is clear and any prescribed treatment is complete.

Impetigo commonly presents as fragile fluid-filled blisters, red patches, erosions or crusted sores. The scrotal skin may feel itchy, tender, raw or mildly swollen. Scratching can transfer bacteria to nearby skin, including the groin and upper thighs, and touching the area can spread infection to the hands or other people. Crusting skin can occur with impetigo, but crusting alone does not establish the diagnosis. A rash limited to the scrotum may also reflect irritation from soaps, moisture, friction or a pre-existing skin condition such as atopic dermatitis.

Arrange a medical appointment for new, spreading or weeping sores on the scrotum. Until then, wash your hands before and after touching the area, rinse gently with lukewarm water, pat dry and keep the skin as cool and dry as practical. Do not pick crusts, share towels or apply steroid, antiseptic or leftover antibiotic products unless a clinician advises it. Wear loose, clean underwear and change it when damp. Launder towels, underwear and bedding regularly, and avoid close skin-to-skin contact with anyone who has broken skin or a weakened immune system. Treatment may involve a prescribed topical antibiotic for a small localised area or oral antibiotic therapy when infection is more extensive; the choice depends on examination findings.

Seek prompt medical care if redness, warmth, swelling or pain is increasing, if pus is accumulating, or if sores are spreading beyond the scrotum. Get urgent help for fever, chills, marked scrotal swelling, severe pain, darkening skin, vomiting or feeling faint. These features can signal a deeper or more serious problem that is not typical of a minor surface infection. Also arrange prompt review if you have diabetes, reduced immunity, recurrent infections or a recent new sexual partner. Do not delay assessment when a sore is ulcerated, unusually painful or not improving with the treatment prescribed.

You can ask: Does this look like impetigo or another cause of genital sores? Should the area be swabbed? Which cleansing and dressing routine is suitable for scrotal skin? Do I need topical or oral antibiotics? When can I return to sexual contact, work or exercise? What changes should make me seek urgent help? Tell the clinician about new products, shaving, eczema, allergies, recent sexual contact and any medicines you have already applied.
