Post-traumatic eczema

Thirteen cases of eczema that followed acute cutaneous trauma were observed. On the basis of the present case series, the following conclusions may be drawn: 1. Cutaneous trauma may precipitate eczema. 2. The trauma is sufficient to cause obvious tissue damage accompanied by an inflammatory or regenerative response. 3. Eczema usually begins within a few weeks of acute injury at the site of the cutaneous trauma. 4. Eczema may occur as an isolated idiopathic reaction or as an isomorphic reaction either preceding or following the appearance of an endogenous eczematous condition in nontraumatized skin. 5. Individual lesions of post-traumatic eczema may persist or recur for long periods of time. 6. The occurrence of post-traumatic eczema following occupational injury has important medicolegal implications.
