Facial involvement may occur in scleroderma mimics also; in addition, Raynaud phenomenon is not seen in scleroderma mimics.A variety of auto antibodies like ANA, anti-histone, anti-nucleosome, anti U3-RNP, anti fibrillin and anti cardiolipin are seen in patients with morphea.

Takehara K, Sato S. Localized scleroderma is an autoimmune disorder. Rheumatology (Oxford) 2005;44:274-9Several therapies have been used. These include topical tacrolimus, imatinib, bosentan, methotrexate, UVA, mycophenolate and retinoic acid.

Br J Dermatol 2009;160:1075-82Most commonly seen in children and adolescents. Lesions involving the face or scalp: en coup de sabre lesions. Parry-Romberg syndrome: hemi-facial atrophy of tissues below the forehead with little involvement of the skin. This disorder and linear scleroderma frequently co-exist and are often bilateral.

Atrophoderma of Pasini and Pierini is a form of morphea, with depressed hyperpigmented plaques with a sharp border and lacking inflammation.
