The Koebner phenomenon, where skin lesions appear after trauma, is reported in a patient with pityriasis lichenoides et varioliformis acuta. This case highlights the Koebner response in this specific dermatosis.

Area of Science:

  • Dermatology
  • Immunology
  • Pathology

Background:

  • The Koebner phenomenon is a well-documented response in various dermatological conditions.
  • It involves the isomorphic response of skin lesions following trauma.
  • Its occurrence in pityriasis lichenoides et varioliformis acuta (PLEVA) is less commonly reported.

Purpose of the Study:

  • To document and describe the presentation of the Koebner phenomenon in a patient diagnosed with pityriasis lichenoides et varioliformis acuta.
  • To contribute to the understanding of Koebnerization in rare dermatoses.

Main Methods:

  • Case report of a male patient.
  • Clinical observation and documentation of skin lesions.
  • Diagnosis of pityriasis lichenoides et varioliformis acuta.

Main Results:

  • The patient exhibited the Koebner phenomenon, with new lesions appearing at sites of skin injury.
  • The observed lesions were consistent with the clinical presentation of pityriasis lichenoides et varioliformis acuta.

Conclusions:

  • This case confirms that the Koebner phenomenon can occur in pityriasis lichenoides et varioliformis acuta.
  • Further research may elucidate the specific immunological or inflammatory mechanisms underlying Koebnerization in PLEVA.
