Prurigo Nodularis
Prurigo Nodularis (pronunciation: proo-ri-go no-dew-lar-is) is a chronic dermatological condition characterized by itchy nodules which usually appear on the arms or legs. Patients often have a history of notable itching and scratching.
Etymology
The term "Prurigo Nodularis" is derived from the Latin words "prurigo" meaning "itch" and "nodularis" meaning "nodular".
Symptoms
The primary symptom of Prurigo Nodularis is the presence of hard, itchy lumps (nodules) on the skin. These nodules are typically found on the extremities, particularly the arms and legs. Other symptoms may include dermatitis, eczema, and intense itching that may worsen at night.
Causes
The exact cause of Prurigo Nodularis is unknown. However, it is often associated with other skin conditions such as atopic dermatitis, eczema, and psoriasis. It may also be triggered by certain systemic diseases, including HIV and hepatitis C, or mental health conditions such as anxiety and depression.
Treatment
Treatment for Prurigo Nodularis typically involves managing the symptoms, particularly the itching. This may include topical treatments, such as corticosteroid creams, as well as systemic treatments like antihistamines and immunosuppressants. In severe cases, phototherapy may be used.
