We have gathered clinical and historical data implicating fluoride dentifrices as an important etiologic factor in this dermatosis. The following two cases support this observation.
Report of Cases.—Case 1.—
A 63-year-old woman developed PD in mid-1971 that persisted for 24 months. There were exacerbations and remissions even though she was initially treated for one month with 0.025% fluocinolone acetonide cream and then intermittently with a mixture of 1% hydrocortisone, coal tar, and diiodohydroxyquin (Cor-Tar-Quin) and 250 mg of tetracycline hydrochloride four times a day. In August 1973, it was ascertained that she had been using a fluoride dentifrice for as long
