What is prurigo nodularis

First, prurigo nodularis is a chronic inflammatory skin disease characterized by itching and nodular lesions. The etiology is related to insect bite, gastrointestinal dysfunction, endocrine and metabolic disorders, and neurological and mental factors. This disease is more common in women. Skin lesions occur in the limbs, can also be seen in the waist and buttocks, generally will appear inside the leg.

In the early stage, the papules were from needle cap to rice grain, and gradually increased to be large, hemispherical, solid and uplifted papules and nodules on the surface of mung bean to soya bean. The top of the papules and nodules had obvious keratosis and verrucous appearance. The surface was rough, brown or grayish brown, scattered and isolated, and there was a very tight feeling when touched.

Finally, due to severe scratching, exfoliation, bleeding and blood scab occurred. The skin around the nodules is pigmented or thickened, showing lichen like changes. Nodules are usually found in the extremities, especially in the extensor side of the leg, occasionally in the back. It can be as few as several or as many as dozens, sometimes arranged in strips.
