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.
