ALLERGIC ECZEMATOUS DERMATITIS DUE TO DYES IN NYLON STOCKINGS - CROSS-SENSITIZATION OF PARAPHENYLENDIAMINE

[摘要] In 10 cases of stocking dermatitis the skin tests revealed that the allergy was due to certain yellow and red dyes and not to the nylon fiber, the finishes, softeners and certain other dyes used in the manufacture of the stockings. These yellow and red dyes are azodyes. Sensitization to these dyes was in all our cases of stocking dermatitis associated with cross-sensitization to paraphenyl-enediamine, probably on the basis of group hypersensitivity to compounds of quinone structure as reported by R. L. Mayer (Arch. Dermat. u. Syph. 156: 312. 1928; Klin. Wochschr 7: 1958. 1928; Arch. Dermat. u. Syph. 158: 266. 1929).
