Abstract

  • Psoriasis accounts for 4% of all dermatoses seen in children under 16 years of age

  • Classical lesions of plaque psoriasis are well defined, round, intensely erythematous, and covered with silver white scale

  • In histology, accumulation of neutrophils within a pustule is referred to as the “spongiform pustule of Kogoj” and the accumulation of neutrophils remnants in stratum corneum surrounded by parakeratosis is called “micro abscess of Munro”

  • Auspitz sign is appearance of pin-point bleeding spots when scale is removed from plaque, caused by rupture of dilated capillaries beneath the thinned suprapapillary epidermis

  • Koebner phenomenon is characterised by formation of new psoriatic lesions in otherwise healthy skin

  • Therapeutic modalities for psoriasis are topical therapy, photochemotherapy and systemic therapy

  • Topical therapy includes corticosteroids, vitamin D3 analogues, anthralin, tazarotene, salicylic acid, coal tar and calcineurin inhibitors

  • Obesity, metabolic syndrome and higher risk for developing Crohn’s disease are complications of childhood psoriasis
