Abstract
We experienced a case (an 81-years-old woman) of malignant lymphoma with uveitis, interstitial pneumonia, interstitial nephritis and elevation of serum angiotensin converting enzyme (ACE) and lysozyme level. Though sarcoidosis was suspected, she was diagnosed by autopsy as having malignant lymphoma (peripheral T cell lymphoma, unspecified). It was speculated that uveitis and tubulointerstitial nephritis could be attributed to malignant lymphoma, elevation of serum ACE level to cholestatic jaudice, and interstitial pneumonia to pneumocystis carinii and cytomegalovirus infection. This complicated case of malignant lymphoma is important for clinicians who are concerned with the medical care of sarcoidosis, so we present it here from the point of the differential diagnosis between sarcoidosis and malignant lymphoma.
