- Lentigo maligna (LM) is a subtype of cutaneous melanoma in situ that develops on chronically sun-damaged skin in elderly individuals.
- Diagnosis and management of LM are challenging due to slow progression, occurrence on cosmetically sensitive areas, and subclinical peripheral extension.
- The International Dermoscopy Society formulated evidence-based and expert consensus-driven recommendations for LM management.
- Non-invasive skin imaging techniques like dermoscopy and reflectance confocal microscopy aid in diagnosis, biopsy orientation, and monitoring.
- Multiple partial biopsies help confirm diagnosis and rule out invasion.
- Complete surgical excision is the first treatment option, with margin-controlled techniques preferred for large or ill-defined lesions.
- Topical imiquimod and radiotherapy are effective alternatives when surgery is unsuitable.
- Blind destructive methods should be avoided, and close clinical and imaging follow-up is necessary.
- Patient-centred care, shared decision-making, and a multidisciplinary approach are critical for optimal outcomes.
