Summary
Lentigo maligna, a premalignant skin condition, requires careful treatment selection based on lesion characteristics and patient factors. Mohs surgery offers the lowest recurrence rates for this melanoma in situ.
Area of Science:
- Dermatology
- Oncology
Background:
- Lentigo maligna is a premalignant melanocytic neoplasm on sun-exposed skin in older adults.
- It is considered the in situ phase of lentigo maligna melanoma, with cure as the primary treatment goal.
Purpose of the Study:
- To review treatment options for lentigo maligna.
- To inform dermatologists and surgeons about evidence-based management strategies.
Main Methods:
- Literature review of various treatment modalities for lentigo maligna.
- Comparison of recurrence rates for different treatment approaches.
Main Results:
- Surgical excision is the preferred treatment for histologic clearance.
- Mohs micrographic surgery demonstrates the lowest recurrence rates (4-5%).
- Conventional surgery, cryotherapy, and radiotherapy show good results with 7-10% recurrence.
Conclusions:
- Treatment choice depends on lesion site, size, and patient comorbidities.
- While Mohs surgery offers superior outcomes, other methods are viable.
- Further data is needed for less common treatment modalities.
