Lichen Simplex Chronicus
Symptoms and Signs of Lichen Simplex Chronicus
Lichen simplex chronicus is characterized by pruritic, dry, scaling, hyperpigmented, lichenified plaques (single or multiple) in irregular, oval, or angular shapes. It involves easily reached sites, most commonly the legs, arms, neck, upper trunk, and genital region. It does not occur in areas of the skin that the patient cannot reach, such as the mid back (unless patient uses a back-scratching tool). Prurigo nodularis is a related condition, likely a more prominent manifestation. In this disorder, skin lesions (nodules) are thicker and typically multiple.
