Distinguishing among forms of dermatitis (eg, asteatotic eczema, atopic dermatitis, nummular eczema) may be difficult, but, fortunately, this is not necessary to make proper treatment decisions. [28] Contact dermatitis may have a pattern that approximates the manner in which the offending agent came into contact with the skin, such as a linear pattern. It may become chronic in the setting of repeated exposure, such as with chromates and formaldehyde. The patient may recall contact with an allergen, such as poison ivy.
