Physical urticarias involve skin reactions like hives and swelling triggered by physical factors. This case study details a patient with multiple physical urticaria conditions, including solar urticaria and exercise-induced anaphylaxis.

Area of Science:

  • Dermatology
  • Allergology
  • Immunology

Background:

  • Physical urticarias encompass a spectrum of mucocutaneous conditions.
  • These disorders manifest as whealing and/or angioedema.
  • Symptoms are specifically induced by physical stimuli.

Observation:

  • A case report of a 24-year-old Caucasian male is presented.
  • The patient exhibits ultraviolet A-induced solar urticaria.
  • Additional conditions include food-dependent exercise-induced anaphylaxis and symptomatic dermographism.

Findings:

  • The patient presents with a complex phenotype of physical urticarias.
  • Co-occurrence of solar urticaria, exercise-induced anaphylaxis, and dermographism is noted.
  • Allergic rhinoconjunctivitis is also diagnosed in this individual.

Implications:

  • This case highlights the heterogeneity of physical urticaria presentations.
  • Understanding co-existing conditions is crucial for accurate diagnosis and management.
  • Further research into the underlying mechanisms of multiple physical urticarias is warranted.
