Answer

Because a variety of physical conditions can cause itching and then lesions, these must be excluded or, at least, established as being relatively unlikely before a firm diagnosis of excoriation disorder can be made. Such conditions include the following:

  • Renal disease

  • Cocaine use

  • Opiate use

  • Medication reactions

  • Multiple sclerosis

  • Hepatic disease

  • Lymphoma

  • Pregnancy

  • Internal cancers

  • Uremia

  • Carcinoid

  • Delirium

  • Diabetes mellitus

  • Hypothyroidism

  • Iron deficiency anemia

  • Hyperthyroidism

  • Xerosis

  • Intestinal parasitosis

  • Myeloma may be noted

  • Patients may report headache or menstrual disorders
