E. Papadavid et al., STRICT ANATOMICAL COEXISTENCE OF VITILIGO AND PSORIASIS-VULGARIS - A KOEBNER PHENOMENON, Clinical and experimental dermatology, 21(2), 1996, pp. 138-140
We describe a patient who developed typical psoriatic plaques covering
completely or partly the vitiliginous areas of her skin. Her psoriasi
s was strictly limited to the vitiliginous patches with no involvement
of the normal skin. Strict anatomical coexistence of both diseases is
extremely rare and suggests a causal mechanism, possibly due to a Koe
bner phenomenon, but genetic and environmental factors may also be inv
olved.
