A 59-year-old white female with no previous health problem presented to our dermatology clinic with a lesion on the skin overlying the right scapula. It was asymptomatic, except for occasional pruritus. The size of the lesion had increased gradually from 3 mm to 30 mm over 25 years. At presentation, the lesion was a dry, annular, verrucous, brownish-pink, sharply demarcated plaque, measuring 2 x 3 cm [Figure 1]. Histological examination of punch biopsy (3 mm) specimen, after hematoxylin and eosin staining [Figure 2],[Figure 3], and immunohistochemistry [Figure 4] were done to study the characteristics of the lesion.
