Most Likely Diagnosis: Lichen Sclerosus (LS) of the Penis with Urethral Meatal Stenosis/Stricture

How Your Symptoms Fit

What is Lichen Sclerosus?

"Lichen sclerosus affects the glans penis and foreskin of men... Men may report painful erections or erectile dysfunction as well as dysuria and spraying, dribbling, or poor flow of urine. Clinically, gray-white discoloration, purpura, and scarring can be seen, leading to phimosis, paraphimosis, or constrictive posthitis. Additional architectural changes include coronal adhesions, reduced coronal sulcus and rim, and narrowing of the urethral meatus."

Why Two Different Types of Pain?

1. Less water (concentrated urine): High acidity + salt concentration irritates the inflamed, damaged urethral tissue - chemical burning pain
2. More water (dilute urine, higher volume): Increased urine flow pushes forcefully through a narrowed meatus - obstructive/pressure pain, dribbling, spraying

What You Must Do - Urgently

1. See a urologist - for urethral meatal dilation or assessment
2. See a dermatologist - for skin biopsy (punch biopsy of the dark area) to confirm LS and rule out early squamous cell carcinoma (SCC) - LS carries a 2-6% lifetime risk of becoming penile cancer
3. Do NOT delay - you mention "many years" - longstanding untreated LS increases cancer risk significantly
4. Treatment is topical potent corticosteroids (e.g. clobetasol) applied with a cotton swab to the meatal area, or circumcision if unresponsive

Glans Hypersensitivity - How It Fits Lichen Sclerosus

1. Active Inflammation (Acute Phase)

• Thinned and atrophic (epidermis gets very thin)
• Eroded and fissured in places
• The nerve endings in the dermis sit extremely close to the surface because the protective skin layers have thinned out
• Even light touch triggers pain - this is allodynia (pain from normally non-painful stimuli)

2. Scarring and Structural Change

"The disease usually presents with pruritus, pain, and dyspareunia... Men may report painful erections or erectile dysfunction..."

⚠️ Red Flag - Please Act Now

Immediate Steps:

1. Urologist - examine urethral meatus, check for stricture, may need dilation or meatotomy
2. Dermatologist or Andrologist - punch biopsy of the dark area to confirm LS and exclude SCC
3. Treatment - Potent topical steroid (clobetasol 0.05% ointment) is first-line and can reverse early changes and reduce the hypersensitivity significantly
4. Do not use soap or any irritant directly on the glans - plain water only for washing

⚠️ This is a clinical assessment based on described symptoms. A physical examination and biopsy are essential for definitive diagnosis. Please see a doctor urgently. - Dermatology 2-Volume Set 5e, p. 1496

Treatment for Penile Lichen Sclerosus

STEP 1 - General Measures (Start TODAY)

• Apply white petrolatum (Vaseline) on the glans BEFORE urinating - this coats the sensitive skin and dramatically reduces the burning pain during urination
• Stop using soap on the glans - use plain water or a soap-free wash only
• Wear soft cotton or silk underwear - reduces friction and mechanical irritation on the hypersensitive glans
• Avoid any rubbing or scratching of the area

STEP 2 - First-Line Medical Treatment

Induction Phase (First 1-3 months)

"This alleviates symptoms in the majority of patients, often within weeks... In some patients, there is complete resolution of signs as well as symptoms, with the exception of scarring, which is irreversible."

Maintenance Phase (Long-term, ongoing)

• Clobetasol 0.05% ointment - twice weekly at bedtime (ongoing)
• OR Mometasone furoate 0.1% ointment - twice weekly
• OR Topical calcineurin inhibitor (Tacrolimus 0.1% ointment) - 2-3 times per week
  • Note: Tacrolimus can initially cause burning on application - starting after steroids reduces this

Maintenance therapy has been shown to reduce the risk of developing squamous cell carcinoma (SCC/cancer)

STEP 3 - For the Urinary Symptoms (Urologist Required)

STEP 4 - Second-Line (If Steroids Fail)

• Intralesional triamcinolone acetonide injections (monthly)
• Oral acitretin (retinoid) 10-50 mg/day for 6+ months
• Fractional CO2 laser (for hardened/thick plaques)
• Photodynamic therapy
• JAK inhibitors (newer option)

STEP 5 - Cancer Surveillance (Critical for You)

• Biopsy the dark area NOW - to rule out squamous cell carcinoma
• Yearly examination for life - any non-healing ulcer, nodule, or new lump must be biopsied immediately
• Treated LS has a significantly lower cancer risk than untreated disease

Summary Action Plan

TODAY:        Apply Vaseline before urinating | Stop soap on glans
THIS WEEK:    See a doctor - get prescription for Clobetasol 0.05% ointment
              Book urologist appointment for urethral assessment
URGENT:       Biopsy of black discoloration area to exclude cancer
LONG-TERM:    Maintenance steroid twice weekly + yearly skin check

⚠️ Do not self-medicate with antifungals or antibiotics - they will not help lichen sclerosus. The correct treatment is steroids applied to the right area. See a doctor for prescription. - Dermatology 2-Volume Set 5e, p. 1496-1497
