Key Points

To review the genetic pathways involved in the development of cutaneous melanoma and outline practical molecular testing recommendations for pathologists under the 5th edition WHO classification.
Reviewed the 5th edition World Health Organization (WHO) classification system for melanocytic tumours.
Evaluated the role of cumulative sun damage and molecular genetic alterations across distinct melanoma subtypes.
Synthesized diagnostic guidance and best practices for integrating molecular testing into routine histopathological assessments.
Cutaneous melanoma comprises nine distinct clinicopathological entities defined by specific molecular genetic pathways rather than representing a single uniform disease.
Identified melanoma subtypes demonstrate substantial differences in their biological behaviour and therapeutic responsiveness to medical interventions.
Established practical testing recommendations to help pathologists select appropriate molecular assays alongside standard histopathological classification.

Review outlines nine distinct genetic pathways in cutaneous melanoma, highlighting the necessity of molecular testing for precise tumor classification.

Abstract

Histopathological assessment of melanocytic proliferations remains the gold standard for their correct classification. The most recent 5th edition of the World Health Organization (WHO) classification of melanocytic tumours incorporates cumulative sun damage and, in particular, molecular genetic changes to achieve this task, and recognizes nine different genetic pathways leading to melanoma development. Melanoma is therefore not a single disease genetically, but rather represents nine different well-defined clinicopathological entities that differ in terms of biological behaviour and their response to various treatment modalities. In this article, genetic pathways in the development of cutaneous melanoma are reviewed, and practical recommendations for pathologists with regards to molecular testing are provided.
