Lentigo maligna: diagnosis and treatment

Area of Science:

• Dermatology
• Oncology

Background:

• Lentigo maligna (LM) is an early-stage melanoma subtype.
• It typically appears as a slow-growing pigmented lesion on sun-exposed skin, primarily the head and neck.
• Diagnosing LM can be difficult for both clinicians and pathologists.

Purpose of the Study:

• To provide an overview of current diagnostic and treatment strategies for Lentigo Maligna.
• To synthesize information from existing guidelines, reviews, and case reports.

Main Methods:

• Literature review of PubMed articles and current clinical guidelines.
• Analysis of diagnostic tools including dermatoscopy and reflectance confocal microscopy.
• Evaluation of treatment options such as surgery, radiotherapy, and topical imiquimod.

Main Results:

• Dermatoscopy and reflectance confocal microscopy assist in differentiating LM from other pigmented lesions.
• Histologic examination is the definitive diagnostic method for LM.
• Surgical excision is the primary treatment, with radiotherapy and imiquimod cream as alternatives for non-surgical candidates.

Conclusions:

• Accurate diagnosis of Lentigo Maligna relies on a combination of clinical presentation, advanced imaging, and histopathology.
• Management strategies for LM are evolving, with ongoing research into novel therapeutic approaches.
