A 74-year-old man presented with a several-year history of nodules on the bilateral soles that had never been treated and were asymptomatic. The patient's medical history was positive for quiescent psoriasis vulgaris and tinea pedis but was otherwise unremarkable. Findings from a review of systems were negative.

Physical examination revealed well-demarcated firm, erythematous to violaceous nonblanching nodules with verrucous, cerebriform-fissured centers on the bilateral arched soles (Figure 1). The nodules were without scale and were nontender. There were no other skin lesions of concern. A punch biopsy was obtained from the right sole (Figure 2 and Figure 3).
