Eczema

The Eczemas

The terms ‘eczema’ or ‘vicharchika’are synonymous. They refer to distinctive reaction patterns in the skin , which can be either acute or chronic and due to a number of causes.
Types of Eczemas :

There are two groups of eczemas: Exogenous and endogenous. While overlap between the two groups is common, distinction between them is critical for treatment because avoidance of incriminating contactants takes precedence over other measures in the management of exogenous eczema. The box below shows the classification of the eczemas.Classification of the eczemas :
