    Multiple benign juvenile melanomas, a rare condition in children, can appear in congenital hyperpigmentation areas. This study presents two cases, detailing the lesion's presentation and ultrastructure.

    Area of Science:

    • Pediatric Dermatology
    • Oncology
    • Dermatopathology

    Background:

    • Juvenile melanoma (JM) is a rare benign melanocytic neoplasm primarily affecting children.
    • Congenital hyperpigmentation presents as birthmarks, which can be extensive.
    • The association between congenital nevi and melanoma development is a known concern, though rare in juvenile forms.

    Observation:

    • Two cases of 3-year-old patients presenting with multiple benign juvenile melanomas.
    • The melanomas developed within areas of pre-existing congenital hyperpigmentation.
    • Distinct clinical features of these multiple lesions were observed.

    Findings:

    • Confirmation of multiple benign juvenile melanomas in pediatric patients.
    • Demonstration of JM development within congenital hyperpigmented skin.

  • Detailed description of the ultrastructural characteristics of these rare lesions.

    • Implications:

    • Highlights the importance of monitoring congenital hyperpigmentation for atypical lesion development.
    • Contributes to the understanding of juvenile melanoma pathogenesis and presentation.
    • Informs clinical management and diagnostic approaches for pediatric pigmented lesions.
