Background: A variety of treatment modalities have been proposed to treat keloid scars, but outcomes are often disappointing. Intralesional cryosurgery may significantly reduce these scars.
Objective: To evaluate the clinical safety and efficacy of intralesional cryosurgery to treat keloid scars. Feedback from patients on pain, pruritus and aesthetic discomfort was recorded before and after treatment.
Methods: A total of 10 patients with 14 keloid scars resistant to conventional treatments were enrolled in a retrospective study between October 2007 and October 2013. The efficacy of this treatment was evaluated by measuring the reduction in scar surface.
Results: Scar surface was reduced by an average of 58.5% after intralesional cryosurgery treatment for all scars (average pre-operative keloid scar surface: 874.6 ± 954.1 mm2; average post-operative keloid scar surface: 505.8 ± 1,024.7 mm2; p = 0.002). Pain and aesthetic discomfort were significantly decreased after treatment in all patients (p = 0.008 and p = 0.012, respectively).
Conclusion: Our data suggest that intralesional cryosurgery is an effective treatment for keloids.

Article Synopsis
- The study investigates a new treatment approach for patients with stage III melanoma that avoids traditional surgery, proposing to combine cryoablation with immunotherapy.
- Fifteen patients underwent a specific treatment protocol that involved administering immunotherapy followed by cryoablation and further injections, all without any procedure failures reported.
- Results indicate that this combination is feasible with manageable side effects, and over half of the patients showed significant positive responses to the treatment.

Article Synopsis
- Cutaneous squamous cell carcinoma (cSCC) is a common skin cancer that can be serious, especially in older adults, with potential for local progression and metastasis.
- Surgery is the usual treatment, but alternative intralesional therapies may be suitable depending on specific patient factors and clinician expertise.
- This review covers both traditional treatments (like methotrexate and cryosurgery) and cutting-edge options (such as intralesional immunotherapy and oncolytic viruses) that are currently being explored.
