  Introduction Top

Psoriasis vulgaris is a genetically determined inflammatory and proliferative disease, characterized by well-defined erythemosquamous plaques with sil­very white scales. [1] It is quite common in children but psoriasis present at birth is very rare. [2] Atherton et al [3] reported the single case of naevoid psoriasis. The natural history and evolution of our case also fits into the same characteristics.

  Case Report Top

A 1 1 / 2 year-old boy was brought to our OPD­ clinic for the complaints of skin lesions since birth. As per history the boy per se had linear red colored lesions with fine white scales involving the limbs only, gradually lesions appeared on trunk also. The lesions were asymptomatic to begin with but gradually the boy started scratching the lesions. The newer lesions appeared in the surrounding area where the boy scratched and sustained injuries. There was no his­tory of seasonal variation and family history of same ailment. There was no history of any drug intake during pregnancy by mother. On examination there were well-defined, linear, erythematous plaques with silvery white typical scales involving the limbs and over trunk. Scalp also was involved. The lesions showed Koebner's phenomenon and Auspitz's sign was positive.

Routine haemogram and blood biochemistry showed no abnormalities. The histopathology de­picted typical features of psoriasis. Naevus cells were not seen.

  Discussion Top

Congenital psoriasis is rare in occurrance. [2] The characteristic morphological pattern of linear distri­bution permits us to label it as congenital naevoid psoriasis, as done by Atherton. [3] The evolution, clini­cal picture and histopathology confirms it to be a case of congenital psoriasis not the precipitation of psoriatic process over pre-existing linear epidermal naevus. Aim of reporting this is its rarity.
