Morphea is an autoimmune condition characterized by excessive accumulation of collagen in the skin and underlying tissues. Lichen sclerosus (LS) is another connective tissue disease for which an autoimmune cause has been proposed, given the high association with other autoimmune diseases. The coexistence of morphea and lichen sclerosus has been sometimes reported in the literature, and is suggestive of a common pathogenic background between the two diseases. Among various types of morphea, generalized morphea has been associated with an increased rate of autoimmune disease, including LS. We report a case of extragenital LS during the progression of linear morphea into generalized morphea.

Cases of coexistent lichen sclerosus et artrophicus and morphea have been reported. It is controversial that both diseases are single disease-spectrum or entirely separated. We encounterd a forty five year old female with a hypopigmented firm plaque on the left neck. Its histologic feature showed compact orthokeratosis, follicular plugging, atrophy of the stratum malpighii with vacuolar alteration of basal layer, and homogenization of the collagen in the upper dermis (lichen sclerosus et atrophicus). Increased thick collagen bundles were seen in the lower dermis (morphea).

BACKGROUND: Differential diagnosis of lichen sclerosus et atrophicus( SA) and scleroderma is occasionally difficult. OBJECTIVE: The purpose of this study was to attempt differentiation between the two diseases using imrnunohistochemical stain and lectins. MEHTODS: Paraffin-embeddred sections of 4 cases of LSA and 11 cases of scleroderma were evaluated for this study. Using lectins, such as peanut agglutinin(PNA), siybean agglutinin(SBA), Ulex europaeus agglutinin-I(UEA-I) and Dolichos biflorus agglutinin(DBA) and the avidin-biotin-peroxi-dase complex(ABC) technique, differential lectin binding patterns betv een the two diseases were examined. RESULTS: In the case of LSA, PNA and SBA stained the upper and lower spinous layer of the epidermis, and UEA I also stained the spinous layer of the epidermis weakly, but no DBA was stained. In the case of scleroderma, PNA stained not only the spinous layer but also the basal layer, SBA stained the upper half of the spinous layer but not the lower half of the pinous layer of epidermis. But UEA-I stained the vascular endothelial cells of dermis instead of epidermis, and DBA stained only the basal layer of epidermis. CONCLUSION: Staining of these 4 lectins on paraffin-embedded sectians using ABC teehnique could be helpful in differenting LSA and scleroderma.

Lichen sclerosus et atrophicus (LSA) is an inflammatory disease that primarily causes anogenital lesion in middle aged women. We present here a case of facial LSA with an asymptomatic, well-demarcated, whitish to bluish, atrophic patch in a linear pattern on the forehead of a 48-year-old woman. This case showed an atypical clinical presentation and it mimicked en coup de sabre, but the histopathologic results confirmed the diagnosis of LSA.
