Summary
Radiotherapy (RT) effectively treated melanotic freckles (MF), also known as Hutchinson's freckles or lentigo maligna, in five patients. The treatment showed minimal toxicity, excellent local control, and favorable cosmetic outcomes, suggesting RT as a viable therapeutic option.
Area of Science:
- Dermatology
- Radiation Oncology
Background:
- Melanotic freckles (MF), or lentigo maligna, often present treatment challenges with high recurrence rates and potential malignant transformation.
- Limited data exists on the efficacy and safety of radiotherapy (RT) for MF management.
Observation:
- A retrospective review of five patients with seven MF lesions treated with RT was conducted.
- Patients were assessed 8 to 37 months post-treatment for local control, cosmetic results, and toxicity.
Findings:
- All patients achieved complete local control of their MF lesions following RT.
- Favorable cosmetic outcomes were observed in all treated cases.
- Treatment-related toxicity was minimal, indicating a good safety profile.
Implications:
- Radiotherapy (RT) demonstrates significant potential as a safe and effective treatment modality for melanotic freckles (MF).
- Dose recommendations suggest 44 Gy in 11 fractions or higher for optimal outcomes.
- Further research into RT for MF is warranted given its promising results compared to other treatments.
