Dermatologic stereoview card. Front of card depicts a person with Favus. The reverse of the card describes the dermatologic conditions as well as the diagnosis and treatment. Favus is a contagious disease caused by a fungus, the achorion Schonleinii, which grows upon the skin in almost pure cultures and forms peculiar pin head to pea sized, cup shaped colonies called scutula, or sometimes larger, irregular, grayish yellow masses of dry, friable, mortar like material. The earliest lesion is a patch of hyperemia or superficial inflamation from which there may be a slight desquamation of thin gray scales. Then the colonies become visible as bright yellow specks at the mouth of hair follicles. Favus may also be known as Tinea favosa or Porrigo favosa. more...
