How well do physicians recognize melanoma and other problem lesions?

B R Cassileth, W H Clark, E J Lusk

    Journal of the American Academy of Dermatology
    |April 1, 1986

    Summary

    Nondermatologists struggle with diagnosing skin lesions like melanoma and dysplastic nevi. Improved training is crucial for early detection and reducing melanoma mortality.

    Area of Science:

    • Dermatology
    • Oncology

    Background:

    • Cutaneous malignant melanoma incidence is rising.
    • Early detection of skin lesions is vital for treatment.
    • Accurate diagnosis of malignant and precancerous lesions is challenging.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of skin lesions by dermatologists and nondermatologists.
    • To identify deficiencies in training for skin lesion diagnosis.

    Main Methods:

    • 105 nondermatologists and 48 dermatologists reviewed images of 11 cutaneous lesions.
    • Lesions included melanomas, dysplastic nevi, and benign growths.
    • Participants identified the type of skin lesion presented.

    Main Results:

    Related Experiment Videos

  • Nondermatologists showed poor diagnostic accuracy for melanomas (38% correct) and dysplastic nevi (58% unable to diagnose).
  • Only 17% of nondermatologists rated their skin lesion diagnostic training as excellent or good.
  • Dermatologists' performance data was not detailed but implied as a benchmark.

    • Conclusions:

    • Significant improvement in skin lesion diagnostic training is needed for nondermatologists.
    • Enhanced training is essential for reducing mortality from malignant melanoma.
    • Early and accurate diagnosis of skin cancer relies on physician expertise.
