Overview
Lentigo maligna (LM) is a type of melanoma in situ, typically found in sun-damaged skin, particularly on the face and neck, characterized by atypical melanocytic proliferation confined to the epidermis. 2Diagnosis
Clinical examination focusing on atypical pigmented lesions with irregular borders and variable pigmentation.
Dermoscopy can aid in distinguishing LM from benign lesions.
Histopathological confirmation via biopsy is essential for definitive diagnosis.
Awareness of illumination and flash reflex effects during photography can improve diagnostic imaging quality. 2Management
First-line treatment: Cryotherapy has shown efficacy but with notable recurrence rates. 1
Adjunctive treatments: Further cryotherapy or other interventions may be required for recurrent cases. 1Special Populations
No specific data provided regarding pregnancy, pediatrics, elderly, or comorbidities in the given abstracts. 12Key Recommendations
Cryotherapy can be considered as a first-line treatment for lentigo maligna, though close monitoring for recurrence is necessary. (Evidence: Weak) 1
Histopathological confirmation through biopsy is crucial for accurate diagnosis of lentigo maligna. (Evidence: Expert opinion) 2
Attention to photographic technique, including illumination and flash reflex, enhances diagnostic accuracy in clinical documentation. (Evidence: Expert opinion) 2References
