    Summary

    This study details a 44-year-old man with acquired cutis laxa, a rare skin disorder. Findings reveal significant elastic fiber degeneration, leading to skin laxity and systemic complications.

    Area of Science:

    • Dermatology
    • Pathology

    Background:

    • Acquired cutis laxa is a rare connective tissue disorder characterized by loose, sagging skin.
    • It can affect multiple organ systems, indicating a widespread pathological process.

    Observation:

    • A 44-year-old male presented with erythema and progressive development of circumscribed lesions and erythematous plaques with loose skin.
    • Associated symptoms included restrictive ventilatory insufficiency, vocal cord elongation, and colonic diverticulosis.

    Findings:

    • Skin biopsies demonstrated diminished and degenerated elastic fibers with abnormal amorphous material and microfibrils.
    • Ultrastructural analysis revealed changes in elastic and collagen fibers, suggesting an inflammatory and degenerative process.
    • Histological findings correlated with the clinical presentation of widespread connective tissue abnormalities.

    Implications:

    • The findings suggest a complex interplay between elastic fiber degeneration, inflammation, and collagen remodeling in acquired cutis laxa.
    • This case highlights the multisystemic nature of the disorder and the importance of comprehensive evaluation.
    • Understanding these pathological mechanisms may guide future therapeutic strategies for connective tissue disorders.
