title: Ultrastructural identification of Langerhans cells in seborrheic keratoses.
abstract: Lesions of seborrheic keratoses studied by transmission electron microscopy showed an unusually large number of Langerhans cells in the epidermis. The role of Langerhans cells in the development of these lesions needs further study.
