. Histological sections stained with H & E (A) and silver stain (B) show the typical morphological features found in patients with cutaneous lacaziosis. (A) The yeastlike cells of are poorly stained with H & E and are observed as empty round structures surrounded by an area of granulomatous reaction. (B) The presence of abundant yeastlike cells in chains is the main feature in silver-stained sections. (C) Numerous yeastlike cells of in chains connected with slender tubules and containing small dancing bodies in their cytoplasm. Magnification for all panels, ×40. Panels A and B are courtesy of P.
