The lesions shown are from the hypogastrium of a 55-year-old white man (Figure 1), the face of 54-year-old white woman (Figure 2), and the thorax of a 39-year-old white man (Figure 3) (size bar, 2.5 mm). All 3 lesions reveal a similar pattern: a polylobular, white-yellow, amorphous structure in the center with a surrounding crown of vessels that do not cross the centers of the lobules. This pattern is caused (1) by inverted lobules of hyperplastic squamous epithelium that expands into the underlying dermis separated by fine septae of compressed dermis and (2) by vessels in this dermis. The recognition of this pattern is very helpful in the clinical diagnosis of molluscum contagiosum in adulthood.
