AB The  eczematous  reaction  pattern  encompasses  a  wide  variety  of  primary  and  associated  secondary  lesions.  Eczema  may  be  classified  morphologically  according  to  its  chronicity.  Table  8.1  lists  the  morphologic  findings  of  acute,  subacute,  and  chronic  eczema.  Acute  eczema  involves  the  constellation  of  vesicles  and/or  bullae,  erythematous  macules  and/or  plaques,  oozing,  and  crusting  (Figure  8.1).  Early  erosions  may  be  seen.  Subacute  eczema  is  defined  by  the  presence  of  scaly  erythematous  papules  and/or  plaques,  along  with  round  erosions  and/or  round  crusts  (Figure  8.2A,B).  In  chronic  eczema  there  are  scaly,  lichenified  plaques  that  may  be  hyper-  and/or  hypopigmented  (Figure  8.3).  Lichenification  connotes  thickened  skin  with  increased  skin  markings  and  this  finding  occurs  secondary  to  scratching  and  rubbing.
