Last edited: 4/10/2026

Overview

Lentigo maligna melanoma (LMM) is a subtype of cutaneous melanoma. Management of cutaneous melanoma aims to homogenize treatment approaches for affected patients 1.

Diagnosis

  • Histological confirmation is required for diagnosis 1.
  • BRAF status determination is recommended for patients with stage $\ge$ III melanoma 1.
  • Management

  • Surgical treatment is indicated for stage I-III resectable melanomas 1.
  • Adjuvant treatment with immunotherapy or targeted therapy is recommended for patients with stage III melanoma 1.
  • For unresectable or metastatic melanoma, treatment with immunotherapy or targeted therapy is recommended 1.
  • The optimal sequence of immunotherapy or targeted therapy for unresectable or metastatic melanoma remains unclear 1.
  • Brain metastases require consideration for both systemic and local treatment 1.
  • Key Recommendations

  • Histological diagnosis is mandatory for melanoma 1. (Evidence: Expert opinion)
  • BRAF status determination should be performed in patients with stage $\ge$ III melanoma 1. (Evidence: Expert opinion)
  • Surgical treatment is the standard for stage I-III resectable melanomas 1. (Evidence: Expert opinion)
  • Adjuvant immunotherapy or targeted therapy is recommended for stage III melanoma 1. (Evidence: Expert opinion)
