Summary
Most melanoma patients do not link trauma to their condition. While some patients report trauma, scientific evidence does not support single or persistent traumatic events as a cause of melanoma.
Area of Science:
- Dermatology
- Oncology
- Pathogenesis Research
Background:
- The link between mechanical trauma and malignant melanoma development is poorly understood.
- Traumatic events are sometimes anecdotally linked to melanoma induction, raising medico-legal concerns.
Purpose of the Study:
- To investigate the association between single or recurrent traumatic events and melanoma characteristics.
- To explore patient-reported trauma history in relation to melanoma formation.
Main Methods:
- A retrospective questionnaire study was conducted.
- Data were collected from 369 patients diagnosed with melanoma.
Main Results:
- Over 91% of patients (337/369) denied any association between trauma and melanoma.
- Only 8.7% of patients (32/369) believed trauma was likely linked to their melanoma.
- Among those who reported trauma, some described single events, persistent irritation, or irritation of pre-existing nevi.
Conclusions:
- The study found no evidence supporting single or persistent traumatic events as a causative factor for melanoma.
- Acral melanoma and melanomas on extremities may be more frequently associated with trauma history, warranting further investigation at these sites.
