"Diaper Dermatitis" from Allergens Excreted in Urine

Discussions of "diaper dermatitis," although recognizing several categories, seem never to separate it into the pubic-perineal type as distinct from the peri-anal, belt-line, or generalized types. This topographical classification gives important clues as to its etiology and treatment. In 1952 a little 1-month-old baby girl who was entirely breast fed, developed an unusually severe pubic-perineal "diaper dermatitis" which was refractory to any form of local treatment, including exposure to warm dry air without a diaper.
