Rhinophyma, a severe form of rosacea, is rare in Japan. Surgical excision is effective for this nasal condition, with cases typically affecting the lower nose and showing no malignancy.

Area of Science:

  • Dermatology
  • Surgical Pathology

Background:

  • Rhinophyma is an advanced stage of acne rosacea characterized by nasal tissue and sebaceous gland hyperplasia.
  • While prevalent in Western countries, rhinophyma is infrequently documented in Japan.

Observation:

  • This study details two Japanese rhinophyma cases treated with cross-shaped full-thickness excision and direct closure.
  • A comparative analysis of rhinophyma in Japan versus Western populations was conducted.

Findings:

  • Only 20 rhinophyma cases, including the two presented, have been reported in Japan.
  • Epidemiological factors for rhinophyma are similar between Japan and the West, with exceptions in tumor location, malignancy, and surgical interventions.
  • Japanese rhinophyma cases predominantly affect the lower nose and are treated via full-thickness excision with skin grafts or direct closure; none have been malignant.

Implications:

  • Understanding geographic variations in rhinophyma presentation and treatment is crucial for effective patient management.
  • The findings suggest that surgical excision is a viable and safe treatment for rhinophyma in the Japanese population.
