The exact rate of<unk> s is unknown. The multiple variant is rare, accounting for less than 10% of all cases. Sex Solitary<unk> s, particularly subungual lesions, are more common in females than in males. Multiple lesions are slightly more common in males. Age Solitary<unk> s are more frequent in adults than in others. Multiple<unk> s develop 11–15 years earlier than single lesions; about one third of the cases of multiple tumors occur in those younger than 20 years. Congenital<unk> s are rare; they are plaguelike in appearance and are considered a variant of multiple<unk> s.
