    Reacting perforating collagenosis (RPC) lesions are caused by superficial trauma, leading to altered collagen bundles being eliminated through the skin. This transepithelial elimination process is a key factor in RPC pathogenesis.

    Area of Science:

    • Dermatology
    • Pathology

    Background:

    • Reacting perforating collagenosis (RPC) is a rare skin condition.
    • The exact cause and mechanism of RPC were not fully understood.

    Purpose of the Study:

    • To investigate the pathogenesis of reacting perforating collagenosis (RPC).
    • To confirm the role of superficial trauma in RPC lesion development.

    Main Methods:

    • Diagnosis of seven patients with RPC between 1974 and 1982.
    • Experimental induction of skin lesions in two patients to observe the disease process.

    Main Results:

    • Superficial trauma was confirmed as a contributing factor in lesion development.
    • The pathogenesis involves transepithelial elimination of altered collagen bundles.

    Conclusions:

    • The transepithelial elimination of abnormal collagen is the primary mechanism in RPC.
    • This pathological process can be seen in various unrelated skin diseases.
