Diagnosis

The distinct, large, isolated pustules, with an inflamed areola and hard base, distributed over the body, ure very distinctive of the disease. It may be confounded with impetigo sparsa, but in this disease there are rather seropustules than pustules, which are very superficial; the discharge is viscid, yellowish; these are as dark scabs, no indurated, inflamed, and painful bases.  Furunculus is deeper, it runs a slower course, and contains a central "slough" or "core," as it is called. It is more circumscribed, and there is little scabbing.
