REPORT OF A CASE
A 52-year-old white man presented with a 2-cm, slightly hypopigmented, firm annular lesion with a slightly elevated border (Figure 1 and Figure 2). The lesion had been present on the right cheek for more than 20 years and had gradually enlarged. In addition, an 8-mm tan-pink nodule that had grown over 6 months was present on the dorsum of the right second toe. Two punch biopsy specimens of the lesion on the cheek were taken to assure a representative sample. A specimen was also taken from the nodule on the toe.A biopsy specimen of the facial lesion is shown (Figure 3 and Figure 4).What is your diagnosis?
HISTOPATHOLOGIC FINDINGS AND CLINICAL COURSE
