title: Seborrheic keratosis with possible central regression.
abstract: We describe a case of suspected superficial-type basal cell epithelioma. However, it showed the histologic features of pigmented seborrheic keratosis and, on the basis of the clinical and histologic findings and the developmental course, was presumed to have undergone central regression. Mononuclear cell inflammation was considered to be involved in the regression.
