INTRODUCTION

KEY POINTS

  • Contact dermatitis can commonly occur in many body areas including periorally, periocularly, periumbilically, and on the extremities with morphology varying from vesicular and bullous to patches and even plaques in chronic disease.

  • In lighter skin, active contact dermatitis is typically pink or red, while in darker skin, it can vary from magenta to violaceous and brown. Often, features of active and chronic disease can be seen simultaneously.

Light-pink to salmon-colored large, scaly, confluent patch along the forehead, with sparing along the hairline and above the eyebrows. This is secondary to para-pheylenediamine.

Dark-brown confluent vesicular plaque along the hairline and on the forehead, with areas of overlying pink macules and brown crusting. On the central forehead are several scattered skin-colored to brown pinpoint papules. Note the intensity of the black hair dye along the hairline. This is secondary to para-phenylenediamine.
