Differentiating Urticaria from other Diseases
- Hereditary or acquired deficiency of complment factor C1
- Cutaneous mastocytosis/urticaria pigementosa
- Malignancy
- Poison ivy contact dermatitis: The rash that develops from poison ivy, poison oak, and poison sumac contact is commonly mistaken for urticaria. This rash is caused by contact with urushiol and results in a form of contact dermatitis called Urushiol-induced contact dermatitis. Urushiol is spread by contact, but can be washed off with a strong grease/oil dissolving detergent and cool water.
- Angioedema: It is related to urticaria. In angioedema, the swelling occurs in a lower layer of the dermis than it does in urticaria.[1] This swelling can occur around the mouth, in the throat, in the abdomen, or in other locations. Urticaria and angioedema sometimes occur together in response to an allergen and is a concern in severe cases because angioedema of the throat can be fatal.
