Serial photography documented a naevus spilus evolving over 12 years, showing increased macules and papules. Biopsy revealed benign melanocytic hyperplasia, supporting monitoring of changing or atypical naevi spili.

Area of Science:

  • Dermatology
  • Pathology
  • Medical Photography

Background:

  • Naevus spilus, a congenital pigmented lesion, can exhibit dynamic changes.
  • Understanding the natural history of naevus spilus is crucial for clinical management.
  • Serial documentation aids in differentiating benign evolution from concerning changes.

Observation:

  • A naevus spilus was monitored using serial photography for 12 years.
  • The lesion demonstrated a significant increase in macules and papules within the café-au-lait background.
  • A biopsy of a newly developed papule was performed.

Findings:

  • Histopathological examination of the biopsied papule revealed lentiginous melanocytic hyperplasia.
  • No signs of cellular atypia were observed in the melanocytic hyperplasia.

  • The observed changes represent a benign evolutionary pattern of naevus spilus.

    • Implications:

    • Periodic clinical photography and follow-up are recommended for large, atypical, or evolving naevi spili.
    • Biopsy indications for naevus spilus should include atypical clinical features or changes in pigmented macules/papules.
    • This case highlights the importance of vigilant monitoring for naevus spilus evolution.
