THE LESIONS shown are from the left side of the neck of a 64-year-old white man (Figure 1), left midbackof a 74-year-old white man (Figure 2), and the left upper chest of a 59-year-old white woman (Figure 3) (size bar, 5 mm). All 3 of these lesions reveal a similarpattern. They have a foggy white to light tan quality with less well-defined white dots (milialike cysts). Dark pigmentation and crisp brown-black circularareas (comedolike openings) are not prominent. The underlying disease process is unknown but it clearly results in a disruption of normal keratinocyticgrowth regulation and results in cellular accumulation. Melanin does not appear to be substantially accumulated in this pattern of seborreheic keratoses.
