Nevocellular nevus presenting as a pigmented area with increased hair growth. It is present at birth but may continue to develop during infancy. Usually, the light brown to black coloured lesions are raised, and deeper nodules may occur. The lesions vary in size from approximately 1 cm in diameter to large expanses, occasionally covering an entire trunk or leg (so-called giant or garment nevi).. Associated abnormalities such as meningeal involvement, spina bifida and club-foot may occur when the nevus is situated over the vertebral column or a limb.
