A 66-year-old woman with a medical history of peripheral neuropathy was seen for a nonpainful, abnormal-appearing, left fifth toenail. The lesion had been present for many years. She denied a history of trauma. Examination revealed thick yellow discoloration and dystrophy of the proximal portion of the nail with underlying nonblanching erythema. The nail plate was surgically removed, revealing a soft, filiform papule (Figure 1) and cavities within the nail plate. Evaluation of routine hematoxylin-eosin–stained sections of the papule confirmed the diagnosis (Figure 2and Figure 3).
