Summary
Malignant melanoma incidence is rising, particularly in women, excluding lentigo maligna. Melanomas developing from moles are rare, indicating a need for further epidemiological research.
Area of Science:
- Dermatopathology
- Epidemiology
- Oncology
Background:
- Malignant melanomas and their precursors pose a significant public health concern.
- Understanding the epidemiology and histological characteristics is crucial for effective management.
Purpose of the Study:
- To investigate the epidemiology and histological nature of primary cutaneous malignant melanomas and their precursors.
- To analyze trends in melanoma incidence over three decades in a specific Belgian region.
Main Methods:
- Data collection by the Mosan Study Group of Pigmented Neoplasms, involving 9 dermatopathologists and 9 laboratories.
- Analysis of epidemiological and histological information on malignant melanomas.
Main Results:
- A consistent increase in primary cutaneous malignant melanomas (excluding lentigo maligna) over the past 30 years.
- Women are twice as likely to be affected compared to men.
- Malignant melanomas arising from preexisting melanocytic nevi are infrequent.
Conclusions:
- The incidence of malignant melanoma, excluding lentigo maligna, is increasing.
- There is a notable gender disparity in melanoma prevalence.
- Further research into the etiology of melanomas developing on nevi is warranted.
