Psoriasis associated with vulval scarring

Psoriasis is a chronic inflammatory skin disorder which is generally not associated with scarring. We report two patients with long-standing severe anogenital psoriasis, that was associated with loss of the labia minora, thus clinically mimicking the scarring associated with lichen sclerosus. Histopathological finding were however, consistent with psoriasis with no evidence of lichen sclerosus. Elastic fibres were present and there was no evidence of abnormal collagen or fibrous tissue. The association of vulval psoriasis with scarring has not been reported previously.
