BACKGROUND Nodular scleroderma is a rare variant of scleroderma which can occur in connection with systemic sclerosis or morphea. A biopsy from the lesion can demonstrate the scleroderma pattern, i.e., keloid pattern or mixed type. Treatment is challenging, and several treatments modalities have been reported with unsatisfactory results. MAIN OBSERVATIONS We present a case of systemic scleros...

Localized waves (LW) are nondiffracting ("soliton-like") solutions to the wave equations and are known to exist with subluminal, luminal, and superluminal peak velocities V. For mathematical and experimental reasons, those that have attracted more attention are the "X-shaped" superluminal waves. Such waves are associated with a cone, so that one may be tempted-let us confine ourselves to electr...

There are several treatment methods for localized scleroderma, but treatment is difficult when the lesion is widely distributed. We encountered a case who was treated successfully with etretinate, a vitamin A derivative. The usefulness of this agent is discussed.

Localized scleroderma is a connective tissue disorder generally involving de entire dermis and usually limited to the subcutaneous tissue; however, it may progress to large indurated plaques, growth retardation, muscle atrophy, and even to flexion deformities or poorly healing ulcers. Unilateral generalized morphea is an extremely rare variant of localized scleroderma which has seldom been repo...
