Early Fibrosis/Plaque in Peyronie's Disease: Penile State for Palpation
In early (≈1 month) Peyronie's disease, fibrosis or plaque is typically NOT palpable in the flaccid state and usually cannot be felt by either the patient or clinician during routine examination of the non-erect penis. 1
Key Clinical Finding
The 2015 AUA Guideline explicitly states that in typical early presentation: "The patient and clinician usually cannot palpate any abnormalities on the penile shaft in the non-erect state." 1 This is a defining characteristic that distinguishes early active disease from later stable disease.
Understanding Active vs. Stable Disease Phases
Active Disease (Early Phase - Including 1 Month)
- Plaques may not be fully developed at this stage 1
- The patient "may or may not manifest the presence of penile induration" 1
- Pain with or without erection is the defining symptom, not palpable plaque 1
- Deformities are still evolving and dynamic 1
Stable Disease (Later Phase - After ≥3 Months)
- Plaques become palpable or apparent on ultrasound 1
- Physical findings are consistent and unchanging 1
- This is when examination in the flaccid state becomes more reliable
Clinical Examination Approach
The guideline recommends examining the stretched and palpated flaccid penis during initial assessment 1, but acknowledges this often yields negative findings early on.
For definitive plaque assessment, clinicians should perform intracavernosal injection (ICI) testing to evaluate the penis in the erect state, where plaques, deformity, and pain can be properly assessed 1. This is particularly important before any invasive intervention.
Important Clinical Pitfall
Do not dismiss Peyronie's disease based solely on negative palpation findings in early presentation. Penile curvature with pain may be diagnostic even without palpable abnormalities 1. The absence of palpable plaque in the flaccid state at 1 month is expected and normal for active disease.
Ultrasound imaging can identify early septal lesions that are not clinically palpable 2, and may represent precursor lesions or early fibrotic changes that will later become palpable plaques.
