Chickenpox, characterized by the appearance of erythematous vesicular rash and itchy blisters on the skin, has a high likelihood of leaving scars. In severe cases, areas of skin on the body, particularly the face, may develop pitted or deep scars, which can significantly impact the individual's appearance.

Facial shingles can cause a range of complications, depending on the location of the rash on the patient’s face.

Hand, foot, and mouth disease is a condition that commonly occurs during the summer and autumn, coinciding with other skin conditions and skin lesions in the form of blisters, so it is necessary to differentiate it from diseases caused by Herpes simplex virus infection or chickenpox and shingles.
