Prurigo Nodularis or Picker’s Nodules is a type skin disease that affects the arms and legs first, but can come on any part of the body. These are characterized by very firm Pruritic (itchy) nodules. It is usually there due to abrasion due to mechanical means (scratching). The cause for this condition are still unknown, with treatment very difficult. It is not clear if the bumps appear before scratching or come due to it. The number of bumps vary from 2-200. These nodules appear from time to time, but they may relapse leaving scars. These can cause great depression to the patients. This disease can be due to insect bite reaction, or iron deficiency anemia, gluten enteropathy and HIV infection. The initial treatment for this condition is usually with steroid creams. Antiasthamine creams (Pramoxine, Zonalon) or pills are taken for further relief. If the condition is severe, then these bumps are frozen with the help of liquid nitrogen spray, oral steroids or PUVA (Ultraviolet light therapy). It is better to not scratch as it can aggravate the condition further, but in resistant cases, a biopsy may need to be performed.
