Psychogenic pruritis as a cause of prurigo nodularis: a case report

Prurigo Nodularis is a skin disease, secondary to a chronic scratching behavior. As multiple etiologies were said to be the cause of this condition, no clear pathophysiology has been described, and treatment is still not readily available. An elderly patient presented to the Emergency Department for confusion was found to have multiple excoriating lesions on the abdomen, back and extremities. Multiple treatment regimens were tried to manage this skin disease prior to this admission, with no improvements. This patient was eventually diagnosed with Prurigo Nodularis and treatment was initiated. In this case report we discussed the etiologies, presentation and management of Prurigo Nodularis, while focusing on the case in hand.
