of the chest and on the croup, more rarely on the neck, shoulder, 

 withers or on other parts of the body (Fig. 146). They are 

 either round or semi-circular, or again irregular in shape. The 

 former have a diameter of 4-8-15 cm., and may be recognized 

 in that their periphery is formed by a ring 1-3 cm. broad, over 

 ^vhich the hair stands erect or disarranged as a result of an 

 edematous infiltration of the capillary bodies, on account of 

 ■which the ring appears darker and less glistening. Within the 

 ring the skin is not swollen, the hair is smooth, and therefore 

 this portion appears sleek and glistening like the skin outside 



of the ring. The second 

 category of the dollar 

 spots is a very irregular, 

 zigzag-shaped form, fre- 

 quently extending 15-20 

 cm. in one direction, and 

 covered with roughened 

 hair. Besides these spots, 

 lentil to bean-sized nod- 

 ules develop on the skin, 

 over which the hair is 

 also rough ; such nodules 

 are mostly observed on 

 the inner surface of the 

 thighs, in the flanks, and 

 more rarely on the sides 

 of the thorax and on the 

 shoulders. The fourth 

 form resembles urticaria 

 and the designation of 

 "dollar spots" is really 

 appropriate only for this 

 form of eruption. Sometimes on the inner surface of the thigh, 

 sometimes in the flanks, lentil to dollar-sized, uniform protuber- 

 ances appear, over v\'hicli the hair appears rough and dull. The 

 number of the dollar spots may be considerable, even exceeding 

 one hundred. They usuan}^ persist for 1 to 8 days, Avlien they 

 disappear without leaving a trace, whereupon however fresh 

 plaques soon appear on other parts of the body. All forms of 

 eruptions are painless, are not of a higher temperature, and 

 are not associated with itching.

Strausz in Mezoliegyes observed besides the dollar spots a severe 

 vesicular and crustaceous eczema on the alidomen, on the chest, also on 

 tlic croup, and at the base of the tail. The intensely itching eruption 

 ("itch disease") which caused the patients to rub and scratch severely, 

 resisted all ti'catment, hut after a time it was arrested of its owii ac- 

 cord, and finally healed ! later however hair failed to grow on the hair- 

 less spots, and if in these places the pigment of the skin had disappeared 

 the affected part of the body showed a variegated appearance.
