    This study identifies a rare presentation of melanocytic dysplasia in melanoma patients, characterized by skin mottling. Recognizing this pattern is crucial for managing patients prone to multiple melanomas and for family screening.

    Area of Science:

    • Dermatology
    • Oncology
    • Pathology

    Background:

    • Primary cutaneous melanoma diagnosis and management.
    • Understanding melanocytic dysplasia and its variations.
    • High incidence of multiple primary melanomas in certain patient groups.

    Observation:

    • Described an uncommon presentation of melanocytic dysplasia in 15 patients with primary cutaneous melanoma.
    • Macroscopic appearance: diffuse mottling or 'freckling' of excised skin surrounding melanomas.
    • Clinical observation: patients often exhibit multiple moles at other sites and around the melanoma.

    Findings:

    • Histological analysis revealed melanocytic dysplasia, typically lentiginous type, in abnormally pigmented skin.
    • Dysplasia was observed in continuity with melanoma and distant from it, including excision margins.

  • Patients with this presentation demonstrated a high incidence of developing additional primary melanomas.

    • Implications:

    • Recognition of this specific melanocytic dysplasia presentation is vital for patient management.
    • Highlights the importance of prophylactic care strategies for affected individuals and their families.
    • Suggests a potential indicator for increased melanoma risk and the need for vigilant surveillance.
