AB Stasis  dermatitis  results  from  venous  insufficiency,  is  characteristically  distributed  on  the  distal  tibia  above  the  medial  malleolus,  and  appears  early  with  erythematous  patches.  These  can  progress  to  scaling  as  well  as  eczematous  and  weeping  plaques.  Patients  will  often  have  light  brown  pigmentation  distributed  on  the  lower  third  of  the  extremity  due  to  microvasculature  blood  extravasation  (hemosiderin  deposition  secondary  to  increased  superficial  capillary  pressure).  Varicose  veins  are  usually  present,  although  they  are  often  difficult  to  visualize  in  obese  patients.  Patients  with  heart  failure,  cirrhosis,  nephrotic  syndrome,  or  lower  extremity  trauma  are  at  increased  risk  due  to  a  chronic  edematous  state.
