Gingiva from a 3-year-old Iranian boy suffering from Papillon-Lefèvre syndrome was examined by light and electron microscopy. Deep pockets associated with predominantly Gram-negative plaque were present. The gingival lesion was dominated by plasma cells, many of which were degenerate. Russell bodies were a prominent feature. No defect of epithelium was detected.
