Contact dermatitis from clotrimazole.

A 47-year-old man has been presented with acute perianal dermatitis due to Cl+Me-isothiazolinone-containing moistened toilet tissue. The European standard series remained negative except for Cl+Me-isothiazolinone. Three months later, the patient developed a presternal plaque of seborrhoeic dermatitis. A cream containing 1% hydrocortisone in Canestene® cream, mixed with Beeler cream in equal proportion, has been prescribed. Two weeks later, he had an exacerbation of his dermatitis. Patch tests were found positive with the cream and clotrimazole, its active ingredient.
