It starts as a red sore that ruptures, oozes and then forms a honey-colored crust usually occurring around the nose and mouth in children.Contact Dermatitis:
The rash develops on parts that are exposed to various allergens that come in contact with the skin during daily activities.Stevens Johnson Syndrome:
It is a rare, potentially life threatening disorder in which the skin and mucous membranes react severely to a medication or an injection. Usually, it begins with flu-like symptoms followed by a painful red or purplish rash.Candidiasis:
It is a fungal infection of the skin and mucous membranes at various sites of the body, especially in those areas that tend to remain moist.Hand, Foot and Mouth Disease (HFMD):
It is caused by the Coxsackie viruses leading the flu-like symptoms followed by rash and small blisters that ulcerate. These lesions are usually seen on the palms of hands, soles of feet, and in the mouth.Trigeminal Neuralgia:
In this condition, there are brief paroxysms of searing pain felt in the distribution of one or more branches of the trigeminal nerve in the face. Absence of vesicular eruptions easily differentiates it from shingles although the neuralgia may be similar in its distribution.Allergic Dermatitis:
It is an inflammation of the skin caused by an allergen in which the person may have complaints like redness, itching and blisters.
