A 69-year-old man was admitted to the hospital because of painful cutaneous nodules, elevated lipase levels, and abnormal results on abdominal scanning.The patient had been in stable health until 15 weeks earlier, when pain developed in his feet. Two weeks later, articular examination showed firm, nonpitting edema of both ankles and pain on compression of the pedal arches bilaterally. The urine was trace-positive for glucose. The results of laboratory tests are shown in Table 1. The levels of uric acid, total protein, albumin, globulin, aspartate aminotransferase, and alanine aminotransferase were normal. The pattern on serum protein immunoelectrophoresis was normal, and the levels of IgG, IgA, and IgM were normal. A test for antinuclear antibodies was positive at 1:160, with a speckled pattern, and a test for rheumatoid factor was negative. On chest radiography, there was evidence of a previous median sternotomy; there was also stable bilateral pleural thickening, believed to have resulted from exposure to asbestos while the patient was employed years earlier aboard aging maritime ships. The lungs were clear, and the size of the heart was normal.The pain in the feet improved, but pain in all the fingers developed and was relieved to varying degrees *To convert the values for glucose to millimoles per liter, multiply by 0.05551.
