What is to be said about the distribution of the simple erythemata?

The idiopathic rashes, as inferred from the nature of the causes, are usually limited.

The symptomatic erythemas are more or less generalized; desquamation sometimes follows.

Describe the treatment of the simple erythemata.

A removal of the cause in idiopathic rashes is all that is needed, the erythema sooner or later subsiding. The same may be stated of the symptomatic erythemata, but in these there is at times difficulty in recognizing the etiological factor; constitutional treatment, if necessary, is to be based upon general principles. Intestinal antiseptics are useful in some instances.

Local treatment, which is rarely needed, consists of the use of dusting-powders or mild cooling and astringent lotions, such as are employed in the treatment of acute eczema (q. v.).
