Summary
Cryosurgery offers an effective treatment for lentigo maligna, a skin condition with cosmetic and malignant potential. This method provides excellent results comparable to surgical excision, with a low recurrence rate.
Area of Science:
- Dermatology
- Surgical Oncology
Background:
- Lentigo maligna requires treatment for cosmetic reasons and to prevent malignant transformation.
- Surgical excision is standard but often limited by lesion size or location.
Purpose of the Study:
- To evaluate cryosurgery as an effective alternative treatment for lentigo maligna.
Main Methods:
- Thirty white patients with lentigo maligna lesions (1.3-4.5 cm) were treated with liquid nitrogen cryosurgery via open spray.
- Follow-up was conducted to assess recurrence and cosmetic outcomes.
Main Results:
- A low recurrence rate of 6.6% was observed over an average follow-up of 3 years.
- Two recurrent lesions were successfully retreated with cryosurgery.
- Eleven patients with over 5 years of follow-up showed no recurrence.
Conclusions:
- Cryosurgery is a highly effective treatment for lentigo maligna, offering excellent cosmetic and curative outcomes.
- The results of cryosurgery are comparable to those of excisional surgery.
