Overview

Cutaneous melanoma (CM) is the most lethal form of skin cancer, responsible for 90% of skin cancer mortality 1. Early detection and accurate diagnosis are crucial for improving patient outcomes 1.

Diagnosis

  • Clinical diagnosis of melanoma should always be confirmed by dermoscopy 1.
  • Histopathological examination is mandatory if melanoma is suspected 1.
  • Sequential digital dermoscopy and whole-body photography may aid in detecting early-stage melanoma in high-risk individuals 1.
  • Confocal reflectance microscopy can enhance clinical diagnosis in specific situations 1.
  • Melanoma staging follows the 8th edition of the American Joint Committee on Cancer classification 1.
  • For melanomas up to 0.8 mm thick, no further diagnostic imaging is typically required 1.
  • From stage IB, lymph node sonography is recommended; no other imaging is advised 1.
  • From stage IIB/C, whole-body CT or PET-CT combined with brain MRI is recommended 1.
  • From stage IIB/C and higher, mutation testing, particularly for BRAF V600 mutations, is recommended 1.
  • Management

  • (No management information provided in the abstracts)
  • Special Populations

  • (No information on special populations provided in the abstracts)
  • Key Recommendations

  • Melanoma diagnosis requires clinical assessment confirmed by dermoscopy and always followed by histopathological examination 1. (Evidence: Expert opinion)
  • For thin melanomas (≤0.8 mm thickness), no further diagnostic imaging is required 1. (Evidence: Expert opinion)
  • From stage IB, lymph node sonography is recommended, but no further imaging examinations are indicated 1. (Evidence: Expert opinion)
  • From stage IIB/C, whole-body examinations with CT or PET-CT in combination with MRI of the brain are recommended 1. (Evidence: Expert opinion)
  • From stage IIB/C and higher, mutation testing, especially for BRAF V600 mutations, is recommended 1. (Evidence: Expert opinion)
