AB |PrintSeborrheic  Dermatitis  at  a  GlanceBoth  infantile  and  adult  forms  exist.It  is  characterized  by  sharply  demarcated,  yellow  to  red  to  brown,  greasy  or  bran-like  scaling  patches  and  plaques.Lesions  favor  scalp,  ears,  face,  presternal  chest,  and  intertriginous  areas.Flares  occur  when  sebaceous  glands  are  most  active  (first  few  months  of  life,  and  post  puberty).Generalized  and  erythrodermic  forms  rarely  occur.The  etiology  is  unclear  but  there  are  associations  with  Malassezia  yeasts,  sebum  secretion  and  composition,  and  certain  drugs.May  be  a  cutaneous  marker  of  HIV  and  AIDS,  especially  when  severe,  atypical,  and  therapy-resistant.
