Rheumatic complications are common in leprosy (Hansen's disease) and can be the primary complaint delaying accurate diagnosis.
Objective:
Such a case is reported here: a 61-year-old woman with indeterminate leprosy presented with symmetric arthritis and purpura. Despite biopsy and evaluation by several physicians, leprosy was not suspected. After 2 years of progressive symptoms, a second biopsy revealed lepromatous leprosy.
Conclusion:
In this case, lack of clinical suspicion and unfamiliarity with the histology of indeterminate leprosy delayed diagnosis and treatment. Leprosy should be considered in the differential diagnosis of patients presenting with unusual rheumatic and persistent cutaneous manifestations.
