A rare papular plaque-type blue nevus, initially suspected as melanoma, was diagnosed histologically. This benign presentation highlights the importance of recognizing uncommon dermatological conditions to prevent misdiagnosis.

Area of Science:

  • Dermatology
  • Pathology

Background:

  • Rare clinical presentations of common diseases can be challenging to diagnose.
  • Understanding these variations is crucial for avoiding diagnostic errors.

Observation:

  • A 6-year-old boy presented with slowly spreading pigmented blue papules on his left foot.
  • The linear arrangement and slow extension over years raised suspicion for malignant melanoma.

Findings:

  • Histological examination of two biopsies confirmed the lesions as a common blue nevus.
  • The papular plaque-type blue nevus shares cellular characteristics with common blue nevi.

Implications:

  • This case adds to the approximately dozen reported instances of papular plaque-type blue nevi.
