Extensive intraoral blue nevus--case report

Area of Science:

• Oral pathology
• Dermatology
• Oncology

Background:

• Nevi are congenital pigmented malformations, infrequently occurring in the oral mucosa.
• Blue nevi, a histological subtype, represent about one-third of oral nevi and possess a notable potential for malignancy.

Observation:

• A case report details a 5 cm blue nevus on the hard palate of a male patient with a history of chronic smoking.
• The management decision favored complete excision over incisional biopsy due to existing literature controversies regarding biopsy of potentially malignant pigmented lesions.

Findings:

• The patient underwent surgical excision of the blue nevus.
• A two-year follow-up revealed no evidence of lesion recurrence or malignant transformation.

Implications:

• This case supports the efficacy of primary surgical excision for large oral blue nevi, particularly when malignancy potential is a concern.
• The findings contribute to the understanding of managing rare oral pigmented lesions and highlight the importance of individualized treatment strategies.
