Prurigo pigmentosa (PP) is a skin condition typically seen in young Asian women. This case highlights PP in a Saudi male after bariatric surgery, successfully treated with minocycline.
Area of Science:
- Dermatology
- Case Study
Background:
- Prurigo pigmentosa (PP), or Nagashima disease, is an acquired dermatosis.
- Characterized by itchy, red eruptions and hyperpigmentation in a reticular pattern.
- Etiology is unknown, but often associated with ketogenic diets.
Observation:
- A 25-year-old Saudi male developed a pruritic rash post-bariatric surgery.
- Diagnosis confirmed via skin biopsy.
- Treated with minocycline and topical corticosteroids, leading to complete resolution.
Findings:
- Presents an unusual case of PP in a non-Asian male following bariatric surgery.
- Demonstrates successful treatment with oral antibiotics (minocycline).
- Highlights PP occurrence independent of ketogenic diet adherence.
Implications:
- Expands the known demographic and potential triggers for Prurigo pigmentosa.
- Suggests bariatric surgery as a potential factor in PP development.
- Reinforces antibiotic therapy as an effective treatment for PP.
