Complications
- Common blue nevi are clinically benign. Lesions tend to persist unchanged throughout life.
- Cellular blue nevi are usually clinically benign. Because of their large size, biopsy and excision tend to be performed more often on cellular blue nevi than on common blue nevi.
- Rare cases of malignant melanoma have been reported to arise in cellular blue nevi. Any change in these lesions is an indication for biopsy or excision.
Prognosis
- The prognosis of blue nevi is excellent.
