  8. 8. LSC / Neurodermatitis • Is the end effect of itch-scratch cycle • Lichenified skin has low threshold for itch • Seen in atopics or other itchy skin conditions
  9. 9. NUMMULAR ECZEMA • Also called discoid eczema • Cause is unknown • But unrelated to atopic diathesis • Incidence peaks in winter, when xerosis is maximal
  10. 10. Dyshidrotic eczema • Also known as Pompholyx • Affects the margins of the fingers and feet . • Lesions are erruptive vesicles and or bullae • About half the patients have an atopic background. • Emotional stress is possibly a precipitating factor • There is no evidence that sweating plays a role in the pathogenesis
  11. 11. Asteatoic eczema • Also ‘xerotic eczema • Winter itch • Eczema crackle • Dehydrated skin showing redness, scaling,and fine crackling resembling cracked porcelain or fissures in the bed of dired lake • Nummular lesions could occur , but Xerotic nummular lesoins are less weepy than classic nummullar eczema

  14. 14. Pathogensis • Pityrosporium ovale is said to play a role in the pathogenesis • Increased sebum production (especillay in infants ) • SD has bimodal age occurecne • During infancy ( peak = 3/12) • Beyond puberty (peak = 4-7 decade) • Treatment • Topical antifungals / topical steroid • Systemic fluconazole
  15. 15. Treatment • ‘’If the lesion is wet , Dry it and if it is dry wet ‘’it . • ‘’Wet for wet and Dry for Dry lesions’’ • Acute eczema – Soak the lesions with antiseptics and drying agents like potassium permanganese 1 : 40000 – Topical steroids lotions /creams
