The old name for this affection is pityriasis versicolor. It consists in an eruption of slightly elevated, irregularly shaped, yellowish, or brownish spots, most often found upon the chest. This is also a parasitic disease. The microscopic appearance of the fungus peculiar to it is shown in Fig. 347. It is often mistaken for "liver spots." It is contagious; may last any length of time.

The Treatment of Tinea Versicolor

Wash the parts and the whole body thoroughly every day with soap and water, and then apply any of the remedies recommended for ringworm. It is not difficult of cure; but treatment should be continued for some time after the eruption disappears, in order to insure a permanent cure.
