Treatment of Peutz-Jeghers Syndrome Mucocutaneous Pigmentation for Cosmetic Reasons
Patients with Peutz-Jeghers syndrome may present with distinctive mucocutaneous pigmented lesions and request treatment for cosmetic reasons. A structured evidence-based approach guides management in this specific scenario.
Clinical Scenario
Blackish brown or brown macules, 1–5 mm in diameter, located on the lips, buccal mucosa, fingertips, phalanges, and heels. The patient requests treatment for cosmetic reasons.
Treatment Approach
Laser treatment of the pigmentations is weakly recommended when the patient requests cosmetic management. Several laser modalities have been applied in this setting, each targeting the characteristic lesions.
The full regimen — including specific laser selection, parameters, and clinical decision pathway — is available in the complete protocol.
Treatment Goals
Non-recurrence of pigmentation, assessed over an observation period following treatment.

- Laser treatment of pigmentations is weakly recommended if the patient requests treatment for cosmetic reasons.
- The lesions are blackish brown or brown, 1–5 mm in diameter, and usually longitudinal in shape.
- Laser therapy for pigmentations in patients with PJS has been performed using a Q-switched ruby laser, Q-switched alexandrite laser, Q-switched Nd (YAG) laser, pulsed ruby laser, argon laser, potassium titanyl phosphate (KTP) laser, erbium (YAG) laser, carbon dioxide laser, and intense pulsed light, all of which are effective.
- There were several reports indicating that Q-switched laser irradiation was effective, and among them, the Q-switched alexandrite laser was effective in a total of 60 cases, including 14 cases in which non-recurrence was confirmed during a median observation period of 2 years.
