AB  - |PrintParapsoriasis  at  a  GlanceAlso  known  as  parapsoriasis  en  plaques.Parapsoriasis  occurs  worldwide  and  affects  mainly  adults.Large-plaque  parapsoriasis  (LPP)  and  small-plaque  parapsoriasis  (SPP)  are  recognized.Large  and  small  “plaque”  lesions  actually  present  as  flat  patches  rather  than  infiltrated  plaques.Lesions  are  chronic  and  favor  nonsun-exposed  skin;  LPP  may  be  poikilodermatous.Pathology  consists  of  superficial,  mostly  CD4+  T-cell  infiltrate;  dominant  clonality  is  more  common  in  LPP  than  in  SPP.LPP  appears  to  exist  on  a  continuum  with  patch-stage  mycosis  fungoides  (MF)  and  progresses  to  overt  MF  at  a  rate  of  approximately  10%  per  decade.SPP  has  minimal  risk  of  progression  to  overt  MF  in  the  experience  of  most  experts.Treatment  options  include  topical  corticosteroids;  ultraviolet  B  (UVB)  irradiation,  and  psoralen  and  ultraviolet  A  (UVA)  irradiation;  excimer  laser;  and  topical  cytotoxic  drugs.
