Is it normal for eczema patches to develope hard, firm nodules?

Prurigo Nodule: Nodular prurigo can occur at all ages but mainly in adults aged 20-60 years. Both sexes are equally affected. The individual prurigo nodule is a firm lump, 1-3 cm in diameter, often with a raised warty surface. The early lesion may start as a smaller red itchy bump. Crusting and scaling may cover recently scratched lesions. Older lesions may be darker or paler than surrounding skin.
