What is a pyogenic granuloma?

A pyogenic granuloma is characterized as a lump of red tissue that forms, typically due to irritation, trauma, or hormonal changes. It commonly appears at the nail bed and may extend to the nail plate, often presenting as a smooth, shiny, and red bump. This condition is not caused by an infection but is a reactive growth that can occur in various parts of the body, including the fingers and toes. Understanding that pyogenic granulomas are not related to fungal infections, inflammation of the nail matrix, or conditions causing discoloration like blue fingernails helps clarify their distinctive nature and presentation in dermatological terms.
