About the symptom
Erythema describes the redness of skin. It occurs with any skin infection, injury or inflammation but may also not be associated with any disease.
Possible causes
- Senile lentigo / seborrheic keratosis
Also known as "sun spots". These are caused by skin aging, particularly in areas exposed to sunlight. Some sun spots can become raised, looking like warts.
- Urticaria
An itchy, allergic rash with red bumps, also known as "hives". The causes are broad, ranging from foods and medications to viral infections and bee stings. In most cases, the rash disappears within 24 hours, however medical attention is needed if there is facial swelling or breathlessness.
- Photosensitivity
A condition in which the skin is extremely sensitive to sunlight and ultraviolet rays. It can be caused by medications and autoimmune disease (body's immune system attacking its own cells).
- Atopic dermatitis
- Actinic keratosis
- Prurigo (chronic and acute prurigo, prurigo gestationis, prurigo pigmentosa, polymorphic pregnancy rash, etc.)
- Epidermoid cyst
- Warts
- Rosacea
Viral mucositis
