Fig. 20. Tinea glabrosa (circulate type) due to M. lanosum. A, B and C reveal dissemi- 

 nated lesions with a tendency to coalescence and double rings (an interesting immunologic 

 phenomenon). D, common location for this type of ringworm. E, a dog belonging to the patient 

 shown in D; these lesions yielded M. lanosum on culture. F. lesions of impetigo contagiosa. 

 The ringed lesion on the forehead is suggestive ol tinea, but there wire typical trusted lesions 

 elsewhere.
