title: Unusual structures in the epidermal Langerhans' cells of normal human skin.
abstract: Two unusual structures were found in the epidermal Langerhans' cells of normal human adult skin: (1) an intramitochondrial crystalline lattice structure composed of numerous electron-dense, fine particles approximately 90 A in diameter, with a lucent spacing of nearly 90 A; (2) bundles of unusual cytoplasmic tubular structures, approximately 120 A wide.
