    Summary

    This case study describes a golden yellow knee lesion resembling lichen aureus in a 29-year-old. Histology confirmed the diagnosis, noting capillary fragility but no venous issues.

    Area of Science:

    • Dermatology
    • Histopathology

    Background:

    • Lichen aureus is a rare form of localized cutaneous iron deposition.
    • Diagnosis typically relies on clinical presentation and histopathological examination.

    Observation:

    • A 29-year-old patient presented with a two-year history of a smooth, non-infiltrated, golden-yellow lesion on the left knee's interior surface.
    • The lesion's appearance was suggestive of lichen aureus.

    Findings:

    • Histopathology and Perls' coloration confirmed the diagnosis of lichen aureus.
    • The patient exhibited capillary fragility.
    • No venous incompetence or plaque anomalies were detected.

    Implications:

    • This case highlights the importance of considering lichen aureus in the differential diagnosis of unusual knee lesions.
    • Further investigation into the pathogenesis of cutaneous iron deposition may be warranted.
    • Understanding associated vascular findings like capillary fragility is crucial for comprehensive patient assessment.
