Superficial morphea: 20‐year follow up in a patient with concomitant psoriasis vulgaris

Abstract

Superficial morphea, a newly described variant of morphea, manifests clinically with hypopigmented or hyperpigmented patches that lack induration. The lesions show on biopsy dermal sclerosis in the superficial to mid-reticular dermis. So far, all cases reported in the literature were skin limited. In this report, we describe a 24-year-old female patient who developed at the age of 4 years plaques characteristic, both clinically and histologically, of superficial morphea. The patient developed later on psoriasis vulgaris. Although the association of scleroderma and psoriasis is rarely reported in the literature, most reports describe a progressive systemic course of scleroderma whenever the two diseases co-exist. This is the first report to describe superficial morphea in association with psoriasis and to provide a 20-year follow-up period during which the superficial morphea remained relatively stable with no evidence of systemic involvement.
