This study reports a rare case of dysplastic pointillist nevus, a benign melanocytic nevus variant. The findings highlight the importance of careful dermatoscopic and histologic evaluation for accurate diagnosis.

Area of Science:

  • Dermatology
  • Pathology
  • Oncology

Background:

  • Pointillist nevus is a rare, benign melanocytic nevus characterized by variegated pigment.
  • Only three cases have been documented in existing literature.

Observation:

  • A 24-year-old male presented with an acquired melanocytic lesion featuring multiple, tiny pigmented dots.
  • Dermatoscopy showed multiple brown globules against a reddish, skin-colored background.
  • Histologic examination revealed architectural disorder and cytologic atypia.

Findings:

  • This case represents a dysplastic pointillist nevus, a previously unreported variant.
  • The combination of clinical, dermatoscopic, and histologic findings is crucial for diagnosis.

Implications:
