Outgrowth of normal bone tissue most commonly found in the great toes. It presents as a solitary, pink or flesh-coloured, firm swelling below the nail that may attain a size of 8 to 10 mm in diameter. X-ray examination will confirm the diagnosis. Lesions usually develop in older children, adolescents, or young adults and are often precipitated by trauma, although they may also evolve spontaneously.
