Recalcitrant leg ulcer due to mixed connective tissue disease.

We present a 28-year-old woman with mixed connective tissue disease (MCTD) complicated by a recalcitrant longstanding leg ulcer, which responded to complex therapy with local polydine, systemic ciprofloxacin, iloprost, enoxaparin and aspirin. Cyclophosphamide pulse therapy and corticosteroids controlled the systemic inflammation but failed to heal the leg ulcer. We considered a rationale of complex therapy for the leg ulcer on a basis of pathogenesis and complications of MCTD.
