RT Journal A1 Schwartz R, Vickerman CE T1 MUehrcke's lines of the fingernails JF Archives of Internal Medicine JO Archives of Internal Medicine YR 1979 FD February 1 VO 139 IS 2 SP 242 OP 242 DO 10.1001/archinte.1979.03630390094033 UL http://dx.doi.org/10.1001/archinte.1979.03630390094033 AB Paired narrow transverse fingernail lines as described by Muehrcke developed in a 64-year-old woman. This patient had lung cancer and was receiving multiple cytostatic agents. Her serum albumin level was normal when this nail finding was quite prominent. There was no history of a markedly reduced serum albumin level. Accordingly, her nail alterations may represent another example of chemotherapy-induced nail changes.(Arch Intern Med 139:242, 1979)
