Geographic, polygonal, light-brown scales and fluorescent bright-blue margins: Characteristic dermoscopic clues for granular parakeratosis

Key Points

• Light-brown geographic scales and bright-blue margins are effective diagnostic clues for granular parakeratosis.
• Clues from dermoscopy and UVFD provide non-invasive ways to identify granular parakeratosis with accuracy.
• The reliable diagnostic potential emphasizes the importance of using these specific dermoscopic features.
• Further validation may enhance accuracy in identifying granular parakeratosis through these observed clues.
