A 65-year-old man presented with 2 slowly enlarging skin lesions on his abdomen (Figure 1). The upper, darkly pigmented, warty lesion was diagnosed as a typical seborrheic keratosis and removed by curet and cautery. The lower, pearly pink, slightly warty lesion was excised, and the specimen was stained with hematoxylin-eosin (Figure 2).
