ABSTRACT
BACKGROUND: We report a case of leprosy observed in a French woman who had lived in Africa 30 years earlier. The clinical presentation was misleading, suggesting connective tissue disease. CASE REPORT: A 69-year-old woman was hospitalized in April 1996 for inflammatory joint disease. The first manifestations had developed three years earlier and the patient had been on systemic corticosteroid therapy associated with anti-malarials since 1993. The clinical presentation progressively included neurological and skin manifestations. Histology examination gave the diagnosis of lepromatous leprosy. Three-drug anti-leprosy treatment in one oral dose was initiated. DISCUSSION: Chronic Mycobacterium leprae infection usually leads to overt leprosy with neurological and cutaneous involvement. Rheumatological forms are less common and found almost exclusively during leprous reactions. The association of inflammatory join pain with neurological and skin manifestations wrongly suggested vasculitis. In addition, the general corticosteroid therapy certainly was implicated in disease activation and progression to a purely lepromatous form.
