We have confined our discussion of perinephric abscesses in this paper to those of hematogenous origin. In these cases there is usually an antecedent history of skin infection. The disease comes on suddenly in an otherwise perfectly healthy individual, in whom generally there has not been previous disease of the kidney or surrounding organs.
We have used the term "acute hematogenous perinephric abscess" because of the close similarity between this disease and acute hematogenous osteomyelitis. We have for years noted the similarity of these two apparently widely dissimilar diseases. They both follow pyogenic skin infections. This infection may take the form of an eczema or some slight injury to the skin surface which has become infected or, as is most frequently the case, may follow boils or carbuncles. These infections of the skin may be of slight moment, and unless a careful history is taken may easily be overlooked by
