Area of Science:

  • Dermatology
  • Immunology
  • Pathology

Background:

  • Eosinophils possess granules with mediators implicated in skin disease.
  • Eosinophil infiltration is noted in many skin disorders.
  • Few conditions, such as Wells' syndrome, angiolymphoid hyperplasia with eosinophilia, and granuloma faciale, show eosinophil patterns central to histopathology.

Purpose of the Study:

  • To explore the role of eosinophils and their mediators in cutaneous disease pathogenesis.
  • To highlight specific skin conditions where eosinophil infiltration patterns are diagnostically significant.

Main Methods:

  • Histopathological examination of skin biopsies.
  • Immunofluorescence studies to detect eosinophil degranulation in skin lesions.

Main Results:

  • Eosinophil infiltration is a feature in numerous cutaneous diseases.
  • Specific patterns of eosinophil infiltration are characteristic of Wells' syndrome, angiolymphoid hyperplasia with eosinophilia, and granuloma faciale.
  • Immunofluorescence confirmed eosinophil degranulation in urticaria and angioedema, supporting mediator roles.

Conclusions:

  • Eosinophil mediators are significant in the pathogenesis of certain skin diseases.
  • The pattern of eosinophil infiltration is a key diagnostic feature in specific dermatoses.
  • Evidence supports eosinophil involvement in conditions like urticaria and angioedema.
