Hansen's disease in a patient with a history of sarcoidosis

We report a rare case of concomitant Hansen's disease (HD) and sarcoidosis. Reticulin staining may be a helpful diagnostic tool in establishing the di agnosis of sarcoidosis in skin lesions. The diagnosis of HD can be establis hed despite negative polymerase chain reaction results for the detection of Mycobacterium leprae DNA. Finally, a well-established diagnosis of sarcoid osis does not preclude the development of another granulomatous disorder. H ence, when new lesions developed in a patient with sarcoidosis despite appr opriate therapy, other concurrent diagnoses should be pursued.
