Hepatic sarcoidosis and renal carcinoma

Sarcoidosis is a relatively common, chronic, multisystem disease of unknown ori,ain. It most commonly affects young adults and usually manifests with bilateral hilar lymphadenopathy or pulmonary infiltrates. Alternatively, it may present with protean manifestations. It has been documented in all org ans of the body, with the exception of the adrenal gland. We describe a male patient who presented with hepatic sarcoidosis, with a s clerosing cholangitis-like picture, but without any pulmonary involvement. He was treated with prednisolone and cyclophosphamide, the latter as a ster oid-sparing agent. A few years later, renal adenocarcinoma developed. We po stulate that this could be related to cyclophosphamide treatment. We present this case history for two reasons: (1) sarcoidosis, selectively affecting the liver and lymph nodes but not the lung with its hepatic invol vement mimicking sclerosing, cholangitis, has not previously been reported; and (2) although long-term cyclophosphamide treatment is known be associat ed with malignancy, there is only one previous report of its association wi th a renal adenocarcinoma.
