Axillary granular parakeratosis, a rare skin condition, typically flares in summer. It may be caused by an unusual reaction to antiperspirants affecting skin keratinization.

Area of Science:

  • Dermatology
  • Histopathology

Background:

  • Axillary granular parakeratosis is a rare skin condition.
  • Characterized by recurrent bilateral axillary rash during summer months.

Observation:

  • A 54-year-old woman presented with a 3-year history of recurrent summer rash in both axillae.
  • Clinical examination revealed hyperkeratotic, fissured, and cobblestone plaques in the affected areas.

Findings:

  • Skin biopsy confirmed the histological diagnosis of axillary granular parakeratosis.
  • The observed histology suggests a potential link to external factors affecting epidermal keratinization.

Implications:

  • This case suggests that axillary granular parakeratosis might be an unusual contact reaction.

  • Antiperspirants are implicated as a potential trigger, interfering with normal epidermal keratinization.
  • Further research is warranted to elucidate the specific mechanisms and confirm the role of antiperspirants.
