Treatment of Penile Itching
For penile itching without visible lesions or suspected dermatitis, start with topical hydrocortisone cream applied 3-4 times daily for symptomatic relief, while simultaneously investigating the underlying cause through clinical examination and targeted testing. 1
Initial Diagnostic Approach
The cause of penile itching must be identified to guide definitive treatment, as the differential diagnosis is broad and includes infectious, inflammatory, allergic, and neoplastic etiologies 2, 3:
- Examine for visible lesions: Look for erythema, scaling, ulceration, plaques, or white patches on the glans, prepuce, and shaft 2
- Assess for phimosis: This can harbor moisture, yeasts, and bacteria leading to chronic inflammation 4
- Obtain sexual history: Recent exposures suggest sexually transmitted infections (STIs) 5
- Check for systemic conditions: Diabetes increases risk of candidal balanitis; immunocompromise predisposes to fungal and atypical infections 4
Treatment Based on Specific Diagnoses
Candidal Balanitis (Most Common Infectious Cause)
Male sex partners of women with vulvovaginal candidiasis who have balanitis benefit from topical antifungal agents including clotrimazole cream or miconazole cream applied twice daily for 7-14 days 5. The itching is typically accompanied by erythematous patches on the glans with pruritus or irritation 5.
Contact or Irritant Dermatitis
- Eliminate irritants: Condoms, lubricants, soaps, detergents, and restrictive clothing are common culprits 1, 6
- Apply topical hydrocortisone: Use 1% hydrocortisone cream 3-4 times daily to affected areas 1
- Restore barrier function: Keep area clean and dry; avoid excessive washing 6
Lichen Sclerosus
First-line treatment is a potent topical corticosteroid applied to the affected white atrophic patches on the glans and foreskin 5. This chronic inflammatory condition commonly causes phimosis in uncircumcised men and carries a 2-9% risk of progression to squamous cell carcinoma, requiring long-term monitoring 5.
Psoriasis
Genital psoriasis often lacks the typical silvery scale due to moisture and maceration, appearing as smooth red plaques 2. Treatment involves topical corticosteroids, though the atypical appearance may delay diagnosis 2.
Sexually Transmitted Infections
If STI is suspected based on sexual history or examination findings:
- For suspected gonorrhea/chlamydia: Ceftriaxone 250 mg IM once PLUS doxycycline 100 mg orally twice daily for 10 days 7
- For herpes genitalis: This is the most common infectious cause of genital ulceration and may present with itching before ulcers develop 2
Scabies or Pediculosis
The penis and scrotum are favorite locations for scabious lesions transmitted through skin-to-skin contact 2. Treatment involves topical permethrin or oral ivermectin, though the latter requires special approval 2.
Definitive Treatment Considerations
Role of Circumcision
Circumcision is the definitive treatment for recurrent or refractory balanitis, especially when associated with phimosis 5, 4. Meta-analyses show circumcised males have 68% lower prevalence of balanitis compared to uncircumcised males 4. However, circumcision does not guarantee protection against all penile dermatoses, and lichen sclerosus may Koebnerize in the circumcision scar 5.
Critical Pitfalls to Avoid
- Do not assume benignity: Plasma cell balanitis, erythroplasia of Queyrat, and Bowen's disease can appear clinically benign but require biopsy to exclude squamous cell carcinoma in situ 2
- Biopsy persistent lesions: Any lesion not responding to appropriate treatment within 2-4 weeks warrants biopsy 5, 2
- Avoid topical calcineurin inhibitors as first-line: Despite some efficacy data, tacrolimus and pimecrolimus have unclear long-term safety profiles and potential neoplastic risk in a disease with premalignant potential 5
- Screen for diabetes: Recurrent candidal infections should prompt blood glucose testing 6
When Symptoms Persist
If itching persists after 2 months of appropriate treatment or recurs, the patient requires re-evaluation with consideration of biopsy 5. Persistent symptoms may indicate:
