A complete clinical examination is necessary for correct diagnosis and a management of your condition. It may not be possible merely on the basis of a picture. Few common differentials for your symptoms are lupus, rosacea and acne. In SLE the malar rash usually starts at the bridge of the nose as a flat or raised redness that may be itchy and scaling. This may be aggravated by sun exposure. This is usually accompanied by other criteria that will fit the picture of SLE. Rosacea on the other hand also may present as a butterfly patterned rash over the face. The skin is red and pustules (small bumps with pus) and comedones are not present. It has a symmetrical involvement over the brows, chin, cheeks nose and ears. Acne is also a possibility. Discuss your concerns with your dermatologist. Treatment will depend on the underlying cause.
Best luck and regards!
