Abstract:
The incidence of lentigo maligna (LM), in situ (LM) or invasive (lentigo maligna melanoma, LMM), has increased during the last decades. Due to functional or cosmetic outcomes, optimal treatment with surgical excision may not be appropriate in some cases. We tried less invasive therapy, immunocryosurgery, as a single treatment for LM or combined with surgery for LMM, with better aesthetic results. Three patients with LM or LMM not amenable to complete surgical excision were selected. LMM patients underwent limited surgical resection of the invasive area. Subsequently, a combined treatment with topical imiquimod and cryosurgery was performed. The LM patient received immunocryosurgery directly. All of them were free of local and systemic disease at 48, 42 and 41 months after discontinuation of therapy. We consider that immunocryosurgery is an alternative option for LM or even for LMM (after removal of the invasive tissue with narrow margins) in poor surgical candidates, with good therapeutic, functional and cosmetic results.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
