Melanoma Risk Assessment and Management

Rationale for Dermatology Referral

The British Journal of Dermatology recommends that patients with a first-degree family history of malignant melanoma and multiple benign nevi should be referred to a dermatologist for evaluation and ongoing surveillance 1, 2, 3
A family history of melanoma significantly increases a patient's melanoma risk, particularly when combined with the presence of multiple benign nevi, according to the British Journal of Dermatology and Genetics in Medicine 1, 2, 4
Individuals with a first-degree relative diagnosed with melanoma warrant specialist evaluation to assess their overall risk profile and determine appropriate surveillance intervals, as suggested by the British Journal of Dermatology 1, 2

Patients with multiple nevi and a family history require expert clinical and dermoscopic examination to distinguish benign nevi from atypical (dysplastic) nevi, which carry additional melanoma risk, as recommended by the British Journal of Dermatology 2, 5, 6
Dermatologists can perform baseline photography to document all lesions, enabling detection of new or changing nevi over time—a critical surveillance tool for high-risk patients, according to the British Journal of Dermatology and Praxis Medical Insights 2, 5, 6

The British Journal of Dermatology suggests that the initial dermatology visit should include a complete skin examination with documentation of all nevi, including size, location, and clinical characteristics 2, 6
Dermoscopic evaluation of any atypical-appearing lesions should be performed to assess for features concerning for melanoma, as recommended by Praxis Medical Insights 5
Baseline photography (both close-up and distant views) should be taken to facilitate future comparison, according to the British Journal of Dermatology and Praxis Medical Insights 2, 5
Patient education on monthly self-examination and the ABCDE criteria (Asymmetry, Border irregularity, Color variation, Diameter >6mm, Evolution/change) is essential, as suggested by the British Journal of Dermatology 1, 2

Patients at moderately increased risk (which includes those with family history and multiple nevi) should receive periodic dermatologic surveillance, though the exact interval should be individualized based on the number and characteristics of nevi found, according to the British Journal of Dermatology 1, 2, 3
Typical surveillance ranges from every 6-12 months for moderate-risk patients, as recommended by the British Journal of Dermatology 1

Rapid growth or darkening of any nevus requires urgent re-evaluation, as suggested by Praxis Medical Insights 5
Bleeding, ulceration, or pain in a nevus are critical warning signs that require urgent re-evaluation, according to Pediatrics and Praxis Medical Insights 5, 7
Development of nodules or color variegation in a nevus requires urgent re-evaluation, as recommended by Praxis Medical Insights 5

Diagnostic shave biopsies should not be performed on suspicious lesions, as this compromises accurate diagnosis and staging if melanoma is present, according to Praxis Medical Insights and the British Journal of Dermatology 2, 3, 6
Partial removal of nevi for diagnosis should be avoided, as this can create a pseudomelanoma picture that causes diagnostic confusion and patient anxiety, as suggested by the British Journal of Dermatology and Praxis Medical Insights 2, 6
