Generally, based on the distribution characteristics of eczema rashes, we can divide it into localized eczema and generalized eczema. Localized eczema occurs in specific areas, such as the hands, ears, vulva, perianal area, breasts, elbow pits, popliteal fossae, and lower legs. These eczema cases generally do not spread but are relatively fixed. Generalized eczema, however, can be locally scattered or spread throughout the body. When care is improper, due to excessive scratching, scalding with hot water, failure to treat promptly or incorrectly, excessive use of steroids, or if it is accompanied by other internal diseases (such as diabetes, hyperthyroidism, etc.) that are not well controlled, then the range of the eczema rashes might spread throughout the body.
