title: Renal failure, paraproteinemia, and lung squamous cell carcinoma.
abstract: A 66-year-old man presented with gastrointestinal symptoms and acute renal failure. He had paraproteinemia and tested positive for antinuclear antibodies. There was no evidence for autoimmune disorder or amyloidosis, and bone marrow biopsy was not consistent with multiple myeloma. Three months later he presented with diffuse lymphadenopathy and right lung mass, and lymph node histology revealed metastatic squamous cell carcinoma. This association of paraproteinemia and nonlymphatic neoplasia is unusual and still very rare. A review of the literature is presented.
