A 27-year-old woman presented with a lifelong history of a rash on the left palm of her hand. On the medial edge of the left hand and the left fifth finger, there was a linear patch of punctate keratotic papules (Figure 1). A punch biopsy specimen was obtained from the left hand and routinely stained with hematoxylin-eosin (Figure 2).
